- The Athletics had a bit of a scare regarding right-hander Austin Adams earlier today in their game against Houston when he was removed from the game due to a bout of left neck tightness. Fortunately, manager Mark Kotsay told reporters (including Martin Gallegos of MLB.com) after the game this evening that Adams is day-to-day and probably could have pitched through the issue if necessary, though the club preferred not to risk it. One of several journeymen making the most of their time in Oakland, Adams has been excellent for the A’s this season as he’s pitched to a 2.65 ERA with a 3.01 FIP across 23 appearances with a whopping 32.9% strikeout rate. Adams has acted as the primary set-up man to star closer Mason Miller this season, and the 33-year-old is controlled through the end of next season, a fact that could make him a particularly attractive target at the trade deadline this summer if he can stay healthy and effective.
Athletics Rumors
Athletics Place Ross Stripling On 15-Day IL, Designate Brandon Bielak
The A’s announced that right-hander Ross Stripling has been placed on the 15-day injured list due to a strained right elbow. Right-hander Brandon Bielak has also been designated for assignment, opening up a 40-man roster spot for Jack O’Loughlin, whose promotion was reported earlier today. In addition to selecting O’Loughlin’s contract from Triple-A, the Athletics also called up righty Tyler Ferguson from Triple-A to take the other 26-man roster spot.
Stripling allowed six runs over 3 2/3 innings in yesterday’s 6-3 loss to the Astros. Even if it is fair to assume that the elbow strain impacted Stripling’s performance in some fashion, it was another in a string of tough outings for the veteran, as he has a 5.82 ERA across 55 2/3 innings and 11 starts for Oakland. His SIERA is a somewhat more palatable 4.66 and Stripling hasn’t enjoyed any batted-ball (.359 BABIP) or strand rate (56.4%) luck, plus his .328 xwOBA is well below his .364 wOBA. The righty’s 4.8% walk rate has been excellent and he has done a very good job of limiting hard contact, though his 13.9% strikeout rate ranks in only the seventh percentile among all pitchers.
Even if the results have been spotting, Stripling has been able to take the ball every fifth day, which is the kind of stability the A’s were hoping to receive when they acquired him in an offseason trade with the Giants. It was widely expected that the Athletics would also be shopping Stripling in advance of the trade deadline, yet this injury now casts doubt on that scenario, and potentially Stripling’s availability for the remainder of the season. More will be known about the severity of the elbow sprain soon, though it is worth noting that Stripling underwent a Tommy John surgery back in 2014 when he was pitching in the Dodgers’ farm system.
The more immediate impact of Stripling’s injury is that Oakland is now down yet another starting pitcher. Paul Blackburn (stress reaction in his right foot), Alex Wood (rotator cuff tendonitis), and Joe Boyle (lower back strain) are already all on the 15-day IL, meaning that of the five A’s pitchers who have made the most starts in 2024, JP Sears is the only fit hurler of the group. O’Loughlin has been a regular starter at Triple-A Las Vegas and will join Sears, Mitch Spence, Joey Estes, and Aaron Brooks in the makeshift rotation. The Athletics have off-days on each of the next two Mondays to allow for some flexibility in figuring out the pitching staff, and in perhaps buying time until at least one of their injured starters is healthy.
Given the short-handed rotation, it seems surprising that the A’s are parting ways with Bielak just nine days after acquiring the righty in a trade with the Astros. Bielak has a 3.18 ERA over 5 2/3 relief innings since coming to the Athletics, and while he has worked exclusively as a reliever over 13 total appearances for Oakland and Houston this season, he started 13 of his 15 games with the Astros in 2023.
Bielak’s Statcast numbers have been troubling in each of the last two seasons, so he might be fortunate to have even the 4.11 ERA he has posted over 103 innings since Opening Day 2023. Still, for a team that is so thin on starting pitching at the moment, designating a swingman with MLB experience puts even more pressure on the Athletics’ internal arms to pick up the slack. The A’s weren’t able to simply move Bielak to Triple-A since he is out of minor league options, and it is possible another team might again look to work out a trade or just claim Bielak in his latest trip to DFA limbo.
A’s To Promote Jack O’Loughlin
The A’s are set to call up left-hander Jack O’Loughlin, The Athletic’s Ken Rosenthal reports (via X). The corresponding move isn’t yet known.
O’Loughlin is a veteran of six minor league seasons, all in the Tigers’ farm system prior to his minor league deal to join the Athletics this past winter. The 24-year-old Adelaide native has also played in parts of four seasons in the Australian Baseball League, and pitched on Australia’s roster during the last World Baseball Classic. This unique career path has now taken O’Loughlin to Oakland and to the doorstep of his Major League debut.
His time in Detroit’s farm system never resulted in any big league call-ups, as O’Loughlin’s 4.78 ERA over 86 2/3 innings with Triple-A Toledo last season wasn’t enough to catch the Tigers’ attention. Somewhat unusually, O’Loughlin has never played any Double-A ball, as the Tigers promoted him from high-A West Michigan to Toledo last season without a stop in between. After catching on with the Athletics this past offseason, O’Loughlin has pitched exclusively at Triple-A Las Vegas, posting a 5.12 ERA over 38 2/3 innings, starting eight of his 10 appearances.
As always with Pacific Coast League numbers, a deeper look is required given the league’s hitter-friendly nature. O’Loughlin hasn’t been helped by a .371 BABIP or a 17.5% home run rate, and the latter statistic stands out as particularly PCL-generated considering that O’Loughlin has done a pretty good job of keeping the ball in the park earlier in his career. His 9.3% walk rate isn’t anything special but he has missed bats to the tune of a 25.6% strikeout rate.
It seems likely that the A’s will give O’Loughlin a look as a starting pitcher, given how Oakland is trying to navigate several injuries within the rotation. Paul Blackburn, Alex Wood, and Joe Boyle have all been placed on the 15-day IL within the last three weeks, resulting in starts for journeyman Aaron Brooks as well as rookie Mitch Spence and Joey Estes. There would appear to be plenty of opportunity here for O’Loughlin to stick around in the majors if he pitches decently well and eats enough innings until the Athletics start to get some of their personnel back.
What’s Mason Miller Worth On The Trade Market?
To say Mason Miller's start to the season has the baseball world buzzing would be an understatement. The second-year A's hurler, whom Oakland selected with the No. 97 overall pick in 2021, has emphatically asserted himself into the conversation for baseball's top reliever. Standing at 6'5" and averaging a comical 101.3 mph on his heater, Miller is the quintessential power pitcher. He's burst out of the gates with a 2.05 ERA in 22 innings, going 9-for-9 in save opportunities and striking out an outrageous 51.9% of his opponents on the year. Eighty-one hitters have had the misfortune of facing Miller. Forty-two of them have gone down on strikes.
Miller allowed two runs in his first outing of the season and was just finally scored upon again yesterday, yielding three earned runs in 1 2/3 frames. Between those two appearances? The right-hander pitched 19 1/3 shutout innings with a 40-to-4 K/BB ratio, fanning an impossible 60.6% of his opponents.
Unsurprisingly, between his dominant performance and the current state of the Athletics, he was quickly speculated upon as a trade candidate -- despite entering the year with six full seasons of club control remaining. As one would expect, teams have inquired. And as you'd also imagine, the asking price is reported to be stratospheric. Miller is going to generate considerable buzz between now and the July 30 trade deadline. Given the massive amount of club control he has remaining, it's a stretch to call him a "likely" trade candidate, but it's a guarantee that teams are going to try. The big question will be how much Oakland will need to be offered to genuinely consider moving him.
Before we dive too far in, let's be clear: this is an exercise without a clear answer. There's no precedent for a pitcher -- or a player -- with this level of early-career dominance and a nearly full slate of six years of control even being available. That we're even talking about it underscores the current state of the A's: a rebuilding team in the midst of relocation whose rebuild has stalled because of nearly universal misses on returns for their top stars. If Oakland were competitive right now or at least seeing enough encouraging returns in the rebuild to think they could be a Wild Card club in 2025-26, this wouldn't even be as serious a topic of discussion.
That's not the world we live in, though. The A's have MLB's fourth-worst run differential and fifth-worst winning percentage. Their farm system ranks near the bottom of the league even after trading Matt Olson, Matt Chapman, Frankie Montas, Sean Murphy, Sean Manaea, Chris Bassitt, Lou Trivino, Sam Moll and more. The A's have painted themselves into a corner that's problematic enough that their juggernaut closer is already being floated as a trade candidate despite barely having a year of service time.
So maybe this is indeed an exercise in futility, but let's take a look at some of the most recent trades for big-name relievers and see what we can glean.

Rob Manfred Discusses Mizuhara, Fletcher Investigations; A’s Stadium Plans
MLB commissioner Rob Manfred spoke to reporters (including Evan Drellich of The Athletic) regarding the league’s ongoing investigations into allegations of illegal sports betting against Ippei Mizuhara and David Fletcher. Mizuhara had worked as Shohei Ohtani’s interpreter during his time with the Angels and joined him in heading to the Dodgers this offseason but was fired on Opening Day amid reports connecting Mizuhara to an illegal gambling operation in California, while Fletcher was connected to that same operation by reporting last week.
As noted by Drellich, MLB’s department of investigations has largely been deferential to federal authorities over the course of the investigations. Manfred suggested that this deferential approach was a necessary one, noting that federal authorities have “a lot more tools” at their disposal than the league does with which to conduct investigations in this situation. Drellich explains that while league investigations regarding legal gambling can be assisted by regulators and alerts received by the league’s central office, no such avenues are available in cases of illegal gambling.
“We have no way to know what an illegal bookmaker is doing,” Manfred said, as relayed by Drellich. “…by definition, in most cases we’re going to be chasing, usually a press report or a criminal investigation.”
Manfred went on to suggest that a more proactive approach to the investigations could risk “interfer[ing] in an unproductive way,” prompting the league’s decision to move slowly in its investigations of these cases while following reporting based on investigations from the news media and federal authorities. Reporting earlier this month suggests that Mizuhara is pleading guilty to charges of bank fraud and subscribing to a false tax return in relation with his alleged theft of more than $16MM from Ohtani to fund his gambling habit.
Aside from his comments on the ongoing investigations, Manfred also discussed the impending relocation of the Athletics from Oakland to Las Vegas and their temporary move to Sacramento following the 2024 campaign while they await the construction of their new stadium in Nevada. Manfred notes that Sutter Health Park in Sacramento, which is the current home of the Triple-A Sacramento River Cats, is set to undergo significant renovations in preparation for the A’s arrival next season. Per Manfred, an entirely new home clubhouse will be constructed for the A’s while the visiting clubhouse will be renovating, the field will have new artificial turf installed, and the stadiums cameras will be upgraded to accommodate big league broadcasts.
In addition to discussing the upgrades being made to the club’s temporary ballpark in Sacramento, Manfred noted that the timeline for construction on the club’s permanent ballpark in Las Vegas is a relatively tight one if the club is to begin playing there in 2028, as previously expected. According to Drellich, Manfred indicated that the A’s would need to break ground in Las Vegas in April 2025 if they’re to be ready for Opening Day 2028. That gives the club less than a year to gather private funding for the stadium project, of which they are reportedly seeking $500MM, and reach an agreement with the Las Vegas Stadium Authority regarding a plan for the club to meet its $1.1 billion in commitments toward the construction of the stadium.
A’s Designate Jordan Diaz For Assignment
The A’s announced a series of roster moves Thursday, placing outfielder Esteury Ruiz on the 10-day injured list with a left wrist strain, selecting the contract of Daz Cameron from Triple-A Las Vegas and designating infielder Jordan Diaz for assignment to open 40-man space for Cameron.
Diaz, 23, was an international signing out of Colombia and eventually jumped onto Baseball America’s list of top 30 prospects in the Oakland system in 2019, the first of five straight years he was featured on that list. He was added to the club’s 40-man roster in November of 2021, keeping him out of the Rule 5 draft. That roster spot came to Diaz after he hit 13 home runs in 90 High-A games that year, slashing .288/.337/.483 overall.
Unfortunately, the results since then haven’t been quite as impressive. He’s hit ten home runs in his 344 major league plate appearances but walked just 5.5% of the time, leading to a line of .227/.276/.358. That production translates to a wRC+ of 79, indicating he’s been 21% worse than league average.
His minor league production was still strong in the past two years but has fallen off a cliff here in 2024. He hit .321/.363/.513 on the farm over 2022 and 2023 but his line is just .204/.288/.327 so far this year. His 9.9% walk rate in 2024 is actually an improvement for him but he has just two home runs in 111 trips to the plate and the batting average is clearly not ideal.
He is now in his final option year, so there was a sort of ticking clock in the background for him this year. Since he’s gotten out to such a poor start, the A’s have nudged him off the roster now in order to open up a spot. They will have a week to try to trade Diaz or pass him through waivers. Perhaps a rival club looking for infield depth will be interested based on his previous seasons. Diaz can play the three non-shortstop infield positions and has even received very brief looks at catcher and left field. He can be kept on optional assignment for the rest of the year and has less than a year of service time at the moment.
Bumping Diaz off the 40-man opens a spot for Cameron, who will replace Ruiz in the club’s outfield rotation. The 27-year-old Cameron signed a minor league deal with the A’s in the offseason and been playing very well in Triple-A this year. He has drawn a walk in 16.4% of his 165 plate appearances and also hit six home runs, leading to a .307/.424/.577 batting line. Even in the hitter-friendly Pacific Coast League, that’s still 46% better than league average. He’s also stolen eight bases in ten tries.
Cameron has impressed in the minors before but has struggled in his attempts to carry that kind of production over to the majors. He received 244 plate appearances with the Tigers over the 2020-22 period but hit just .201/.266/.330 in that time, striking out at a 31.6% clip.
He exhausted his option years in that time and has been in the minors since then, with the Orioles last year and with the A’s so far this year. If things click for him in the majors this time, he can be kept around by the A’s since he has less than two years of service time. For now, he’ll join the club’s outfield mix alongside JJ Bleday, Brent Rooker, Seth Brown and Tyler Nevin.

Tigers Claim Easton Lucas, Designate Ty Adcock
The Tigers and Athletics have both announced that Detroit has claimed left-hander Easton Lucas off waivers. Lucas will be optioned to the Tigers’ Triple-A affiliate in Toledo. In the corresponding move, the Tigers have also designated right-hander Ty Adcock for assignment.
It was a quick stay on the waiver wire for Lucas, as the Athletics only just designated him for assignment two days ago. The 27-year-old has only nine MLB appearances since debuting last season with Oakland, and the results have been rough even within that small sample size. Lucas has a 10.45 ERA in his 10 1/3 career innings, with an ungainly 12.1% walk rate and only a decent 22.4% strikeout rate. The A’s chose to outright Lucas after last season, and he remained in the organization after clearing waivers.
While the numbers in the Show haven’t been much to look at, Lucas does have a 4.37 ERA in 45 1/3 career frames at the Triple-A level. That ERA is quite solid considering that Lucas has spent most of that Triple-A with the Athletics’ affiliate in the hitter-friendly Pacific Coast League, and he has been particularly impressive with a 2.87 ERA in 15 2/3 Triple-A innings in 2024. His strikeout totals since arriving in Triple-A have been below average, after Lucas recorded many more whiffs in the lower minors.
To make room for Lucas, Detroit has moved on from Adcock just a month after claiming him off waivers from the Mariners. Adcock was an eight-round pick for Seattle in the 2019 draft, and he made his MLB debut in 2023 with 15 2/3 innings of 3.45 ERA ball over 12 appearances out of the Mariners’ bullpen. Adcock has yet to allow a walk at the big league level and he had good base-on-ball numbers in the minors prior to this season, when his walk rate suddenly spiked up to 13.63% in 8 1/3 innings with the Tigers’ and Mariners’ Triple-A affiliates.
The small sample size caveat applies again, and it should be noted that this is Adcock’s first time in Triple-A, as the Mariners promoted him from Double-A Arkansas last season without the benefit of any exposure at the top of the minor league ladder. With an 8.64 ERA in Triple-A thus far, obviously Adcock has some adjustments to make, but those could possibly come in yet another organization if the righty is claimed again.
A’s Sign Robert Dugger To Minors Contract
The Athletics have signed right-hander Robert Dugger to a minor league deal, according to Dugger’s MLB.com profile page. Dugger has been assigned to the team’s Arizona Complex League affiliate, indicating that Dugger could be undergoing a mechanical overhaul or simply be getting some Spring Training-esque ramp-up before his next assignment higher up the minor league ladder.
Dugger returns to North American baseball after a brief and unsuccessful stint in the Korea Baseball Organization. After signing a one-year, $750K deal with the SSG Landers over the offseason, Dugger posted a 12.71 ERA over six starts and 22 2/3 innings before being released at the end of April.
Despite those rough numbers, the 28-year-old Dugger could now provide the A’s with some rotation depth, given his more recent track record in the Pacific Coast League. The righty had a 4.31 ERA over 146 1/3 Triple-A innings with the Rangers’ top affiliate in 2023, which stood out as a particularly solid number in a very hitter-friendly league. A 22.6% strikeout rate and 9.5% walk rate weren’t overly impressive, but providing quality innings in the PCL is no small feat, and the Athletics surely have interest in seeing what Dugger can do at their own PCL team at Triple-A Las Vegas.
Dugger is a veteran of four Major League seasons, posting a 7.17 ERA across 86 2/3 innings with the Marlins, Mariners, Rays, and Reds from 2019-22. Never a hard thrower or a big strikeout pitcher, Dugger has relied on control to get good results, though his walk rates have been pretty modest over his last three minor league seasons.
Journeymen Taking Advantage Of Playing Time With Athletics
Opportunities in the big leagues can be fleeting. Jackson Holliday of the Orioles came into this year considered the best prospect in all of baseball. Despite being just 20 years old, the Orioles called him up to the majors this year. But after just 10 games, during which he struck out in half of his plate appearances, he was sent back down to the minors.
Ken Rosenthal of The Athletic recently took an interesting look at the struggles of several young players, including Holliday, but also Colt Keith, Kyle Manzardo, Henry Davis, Jackson Chourio and Wyatt Langford. Several people in the game seem to agree that the gap in quality between Triple-A and the majors is widening.
There are various theories for why that might be happening. J.D. Martinez suggests that the new rules about smaller rosters in the minor leagues are squeezing out some veteran pitchers, reducing the overall quality of arms on the farm. Guardians manager Stephen Vogt views it similarly. Orioles general manager Mike Elias suggests that the scouting in the majors is so advanced that players will have their weaknesses attacked to a much larger degree than in the minors. Rays manager Kevin Cash told the Baseball Isn’t Boring podcast (video on X) that minor league pitchers might be more worried about developing their skills as opposed to results, whereas MLB pitchers will be the inverse.
The reality may be a combination of those factors and more. But whatever the cause or causes, there seems to be a growing consensus among people in the game that the jump to the big leagues is bigger than ever before. For a team like the Orioles that is in a battle in the American League East, this puts them in a tough position. Do you let a player like Holliday learn on the job, improving your team in the long run, even if there’s short-term pain? Or do you construct your roster for the best chance of success today?
For a rebuilding club, the choice is much easier. With a low chance of short-term success, the long-term play is the obvious one. This is one silver lining of not being a competitive club: there’s plenty of playing time for both prospects and former prospects.
This is perhaps something that will become even more important in the current era of baseball. With the recent introduction of the lottery system, rebuilding teams have less access to the top of the draft. For instance, the White Sox have the fifth pick in this summer’s draft. That means they can’t pick higher than tenth next year, even though they are one of the worst teams in baseball right now.
Which brings me around, finally, to the Athletics. Apologies to any inverted pyramid traditionalists who have been pulling their hair out to this point, but I thought all that preamble was interesting framing.
The A’s have been trading away all their best players in recent years and now are naturally giving a lot of playing time to their prospects, either the homegrown variety or the ones they traded for. But they’ve also given some playing time to several former prospects that have bounced around and struggled in other uniforms but are now finding success in green and gold. If these players can keep it up, they could be a part of the next good Athletics’ club or perhaps be traded for yet more prospects, good for the club either way. Let’s take a look at them…
Now 29 years old, Rooker was drafted by the Twins in 2017 and made his major league debut with that club in 2020. In April of 2022, he was traded to the Padres alongside Taylor Rogers in a deal sending Chris Paddack and Emilio Pagán the other way. The Friars mostly kept him on optional assignment and then flipped him to the Royals at the deadline for Cam Gallagher. The Royals also gave him more playing time at Triple-A than in the majors before putting him on waivers in November.
Rooker had continued hitting well at Triple-A but not in the majors. He had received 270 major league plate appearances through the moment he was put on waivers, scattered over three seasons and for three different teams, with a batting line of .200/.289/.379. But in 632 Triple-A plate appearances over 2021 and 2022, he hit 48 homers and walked at a 13.3% clip, leading to a .271/.383/.614 line and 149 wRC+.
The A’s put in a claim and have given Rooker plenty of playing time in the past year-plus. He has been making the most of it, to put it mildly. In 663 plate appearances since the start of last year, he has punched out at a 32.4% clip but also launched 40 home runs. His batting line of .253/.336/.509 translates to a 137 wRC+. He isn’t considered a strong defender, even in an outfield corner, but the A’s surely don’t mind as long as he keeps mashing like this. He plays designated hitter most of the time and has produced 3.5 wins above replacement since coming to Oakland, per FanGraphs.
He came into this year with a service time count of two years and 59 days. He will qualify for arbitration for the first time this winter, and the A’s can control him through 2027, their planned final year in Sacramento. They could keep him around and in the lineup for that time or they could trade him whenever they get an enticing offer, depending on how their view the timeline on their return to contention.
Toro, now 27, was drafted by the Astros back in 2017 and was up in the majors with them by 2019. The trilingual Québécois infielder got limited playing time in Houston and was traded to the Mariners in 2021 alongside Joe Smith, with Kendall Graveman and Rafael Montero going the other way. He got regular playing time with Seattle in 2022 but struggled. Prior to 2023, the M’s flipped him to the Brewers with Jesse Winker, acquiring Kolten Wong and cash in return. The Brewers mostly kept Toro in the minors, only putting him into nine major league games last season. He was traded to the A’s in November of last year.
At the time of the deal, Toro had strong results in the minor leagues, slashing .294/.387/.480 on the farm from 2021 to 2023 for a 119 wRC+. But he had produced a line of just .211/.282/.354 in 934 major league plate appearances.
However, in 165 trips to the plate for Oakland this year, he’s hit four home runs while slashing .288/.339/.444 for a wRC+ of 130. He’s also stolen a couple of bases while bouncing between the three non-shortstop infield positions. He already has 1.0 fWAR on the year. He qualified for arbitration this past winter, making $1.275MM this year, and has two more passes before he’s slated for free agency after 2026.
Nevin is just a couple weeks away from his 27th birthday. He was drafted by the Rockies in 2015 but never made it to the majors in Colorado. In 2020, the Rox acquired Mychal Givens from the Orioles, sending Nevin, Terrin Vavra and a player to be named later to Baltimore. He got bits of playing time with the O’s in 2021 and 2022 but didn’t do much.
He was designated for assignment by Baltimore and flipped to the Tigers for cash, just before the calendar flipped over to 2023. He didn’t hit much in the majors for the Tigers and spent most of the year on optional assignment, exhausting his final option year in the process. That left him out of options going into 2024, which caused him to ride the transactions carousel for a bit. He was designated for assignment by the Tigers in January of this year and flipped back to the Orioles for cash. He didn’t make Baltimore’s Opening Day roster, which put him into DFA limbo again, this time getting claimed by the A’s.
Nevin’s output this year hasn’t been quite as strong as that of Rooker or Toro, but it’s a similar step forward from a guy who has always hit in the minors and is now improving in the majors. From 2022-23, Nevin hit 22 home runs in 576 Triple-A plate appearances, also drawing walks at a 10.2% clip. That created a combined batting line of .315/.394/.522 and a 134 wRC+. But his major league work over those same two years resulted in a line of just .198/.302/.282.
Oakland has given him 130 plate appearances so far this year, and he’s launched four home runs. His 8.5% walk rate is just a hair below this year’s 8.6% league average. His .235/.315/.365 batting line leads to a 103 wRC+, indicating his offensive output has been 3% above league average overall. As mentioned, it’s not as emphatic as the jump from Rooker or Toro, but it’s still miles ahead of what Nevin did in the last two years. He’s also provided the club with some flexibility, having lined up at all four corner spots, allowing them to rotate their prospects into the lineup with ease. Nevin came into 2024 with just over a year of service time, meaning he still won’t be arbitration-eligible after this year and can potentially be retained through 2028.
The A’s have also needed plenty of innings covered on the pitching side, and there are interesting developments there as well. The 33-year-old Adams has been bouncing around the big leagues for years. He debuted with the Nationals back in 2017 and has since pitched for the Mariners, Padres and Diamondbacks. Apart from his 2021 season in San Diego, he’s never topped 32 innings in the majors.
That’s partly due to injuries but also due to a significant lack of command. He finished 2023 with 114 1/3 major league innings under his belt with a 4.17 earned run average. He had always been able to punch guys out, carrying a 33.1% strikeout rate into the season — but also a 14.6% walk rate. Additionally, he’d plunked 31 batters, garnering attention in 2021 when he somehow hit 24 batters, leading the league despite throwing far fewer innings than dozens of starting pitchers.
Adams was outrighted by the Diamondbacks at the end of last year and elected free agency. He initially landed with the Mets on a split deal, holding a roster spot for a few months before they outrighted him. Since he had less than five years of service time then, rejecting the outright assignment would have meant forfeiting the remainder of the money on his contract, so he stayed. The Oakland bullpen took a hit when Trevor Gott required Tommy John surgery, so they sent cash to the Mets for Adams just a few days before the season started.
So far, the move to Oakland is working out brilliantly. Adams has a tidy 1.23 ERA through 19 appearances, striking out 32.8% of opponents. More importantly, his 8.2% walk rate is a bit lower than average and much better than his previous career work. He’s also getting ground balls on 51.6% of balls in play. He won’t be able to strand 84.2% of baserunners forever, but his 2.23 FIP and 2.31 SIERA suggest he would have been posting good results even with neutral favor from the baseball gods. With Mason Miller locking down the closer’s role, Adams has become a key setup arm, with 11 holds already this year.
Adams is making just $800K this season, per the Associated Press, which is barely above the $740K league minimum. He came into this year with four years and 150 days of service, meaning he’s slated to finish the season at 5.150, just shy of the six-year mark required for automatic free agency. That means he can be retained for 2025 via arbitration, which could increase the attraction for a club looking for bullpen upgrades at the deadline.
It might be a stretch to call Erceg a “journeyman” in the common use of the word, since he only played for one other club before coming to the A’s. He was drafted by the Brewers in 2016 and was with them until May of 2023. But he has nonetheless taken a circuitous route to where he is today.
He was initially drafted as a third baseman but didn’t hit much in the minors and transitioned to pitching. His first official action on the mound was in 2021, pitching in Double-A. He threw 47 2/3 innings with a 5.29 ERA. As one would expect for someone new to pitching at a relatively high minor league level, control was an issue. Erceg walked 16.4% of batters faced that year, but his 21.1% strikeout rate was reasonable and he also induced grounders at a strong 56.8% rate.
In 2022, he tossed 61 1/3 innings between Double-A and Triple-A with a 4.55 ERA. His 13.1% walk rate and 24.4% strikeout rate were both gradual improvements over the prior season’s marks. He started 2023 back at Triple-A and was posting similar numbers when the A’s traded for him in May, sending cash to the Brewers. Oakland added him to the roster just a couple days later, and he stayed up with the big league club the rest of the season. Erceg logged 55 big league innings with a 4.75 ERA, 27.1% strikeout rate and 14.3% walk rate in 2023.
He seems to have taken a big step forward so far in 2024, with a 3.18 ERA through 17 appearances. His 11.4% walk rate is still high but better than what he showed last year. He’s also punched out 34.3% of batters faced, a huge jump, while keeping 44.4% of balls in play on the ground. He’s earned a couple of saves and seven holds already this year. His fastball has been averaging 98.5 miles per hour, and he’s also thrown a changeup, sinker and slider.
What to do with Erceg will be an interesting decision for the A’s. On the one hand, he came into this season with less than a year of service time. That means he’s still nowhere near arbitration and can be retained through 2029. He also has a full slate of options.
They could hold onto him to be a part of their next competitive window and part of the team that debuts in Las Vegas. On the other hand, his unusual path means that he’s now 29 years old, with an uncertain future on account of his strange circumstances. Given the volatile nature of relievers and the fact that Erceg has essentially just been a windfall for them, they might be tempted to make him available in trades and try to secure players with more stable paths forward.
Kelly, 31, was drafted by the Padres way back in 2011. Since then, he has bounced to the Orioles, Astros, Phillies and Guardians, mostly in the minor leagues. He was also in indie ball in 2019 and missed the 2020 pandemic year, before resurfacing in affiliated ball in 2021.
He was a starter for most of the early parts of his minor league career but transitioned to the bullpen more recently. In the Astros’ system in 2021, he tossed 50 innings between Double-A and Triple-A with a 2.70 ERA. He struck out 29.5% of batters while walking 8.6%.
Kelly was with the Phillies in 2022 and had a 5.29 ERA in 51 Triple-A innings, but he still struck out 29.1% of batters faced along with a 10.6% walk rate. He got to make a brief major league debut with Philly that year, tossing four innings in June and July before being outrighted off the roster.
He signed a minor league deal with Cleveland last year and ended up having a fine season: 16 2/3 innings of major league work resulted in a 3.78 ERA, 22.5% strikeout rate and 12.7% walk rate. Those walks were obviously on the high side, but Kelly didn’t allow a home run in that time. He also threw 39 2/3 innings in the minors with a 3.40 ERA.
Nevertheless, Kelly was designated for assignment in November and claimed by the A’s. He’s tossed 24 innings for Oakland so far this year with an ERA of exactly 3.00. His 16.2% strikeout rate is well below average, but he’s limited walks to a 7.1% rate and kept 42.3% of balls in play on the ground. He also seems to be doing a good job of limiting damage done by opponents. Per Statcast, his average exit velocity, barrel rate and hard hit rate are all in the 92nd percentile or better. He’s thrown his sweeper more than 50% of the time both this year and last year. It’s not leading to huge strikeout numbers, but hitters seem to be struggling to square it up.
Kelly came into this season with less than a year of service, meaning he can be retained well into the future. He still has a couple of minor league options as well, meaning he can be easily sent down to the minors if his results take a turn. The A’s could potentially just hang onto him for years to come but would also likely be open to trades, given Kelly’s age and that he was just a waiver claim.
________________________________________
Small-sample caveats need to apply to all of this, as we’re still quite early in the season. But for the rebuilding A’s, it would be a nice victory if even a few of the names in this group could maintain their strong starts. The club traded away Matt Olson, Matt Chapman, Chris Bassitt, Sean Manaea, Sean Murphy and others in recent years, with most of the players coming back in those deals having been fairly unimpressive thus far. If they hit the jackpot on a couple of guys in this group from waiver claims and small trades, that would soften the blow of whiffing on those bigger deals. As previously mentioned, rebuilding is mostly painful — but giving shots to journeymen like this is one silver lining, and the A’s have seen some positive results there so far.
