A’s Notes: Diaz, Miller, Jimenez
The A’s are planning to recall infield prospect Jordan Diaz, as first reported by Daniel Álvarez-Montes of El ExtraBase (Twitter link). The 22-year-old infielder has spent the year on optional assignment to Triple-A Las Vegas.
Díaz debuted in the big leagues late last season. The Colombian-born infielder got into 15 games, hitting .265/.294/.327 through his first 51 plate appearances. He only struck out seven times but walked just twice and has yet to connect on an MLB homer. Díaz had posted excellent numbers between Double-A Midland and Las Vegas prior to his promotion, combining to hit .326/.366/.515 in 120 minor league games.
After 11 more contests in Triple-A, Oakland is bringing Díaz back up the majors. He’ll add a bat-first infielder to a mix that also includes Aledmys Díaz, Jace Peterson, Tony Kemp and Kevin Smith. The #12 prospect in the system according to Baseball America, Díaz will look to hit enough to offset questions about his ideal defensive home.
Díaz isn’t the most notable forthcoming prospect promotion for the A’s. Oakland announced earlier today they were promoting pitching prospect Mason Miller to make his big league debut. General manager David Forst subsequently informed the club’s beat that the A’s were planning to keep Miller in the rotation from here on out (relayed by Martín Gallegos of MLB.com). With the revelation it’s not simply a spot start for the 24-year-old, Oakland will have to either turn to a six-man starting staff or bump someone from the rotation.
None of Oakland’s starters has fared especially well thus far. JP Sears has the lowest ERA in the group at 4.60. Each of Shintaro Fujinami, Ken Waldichuk and James Kaprielian has allowed more than a run per inning. Opening Day starter Kyle Muller sports a 7.23 ERA with a modest 15.1% strikeout rate.
Everyone in the group still has minor league options remaining. That could lead to one of them being demoted to Las Vegas, but it’s also possible the club looks into a bullpen or swing role for a struggling starter. The A’s were dealt a hit to the relief corps this afternoon, as righty Dany Jiménez went on the 15-day injured list with a shoulder strain.
Jiménez operated as the club’s primary closer at points last season. He’s picked up the team’s only save thus far in 2023, though his overall results have been rough. The 29-year-old has walked six with only four strikeouts over 6 2/3 innings. He’s allowed four runs and seen sharp dips in his swinging strikes and velocity. It seems clear he has not been operating at full strength. The team hasn’t provided a return timetable, though a shoulder strain prematurely ended his 2022 campaign in late August.
Mets Place Carlos Carrasco On Injured List
The Mets announced this evening that starter Carlos Carrasco is headed to the 15-day injured list, retroactive to April 16, due to inflammation in his throwing elbow. New York recalled reliever Jeff Brigham from Triple-A Syracuse to take the active roster spot. The club also announced that reliever Dennis Santana cleared waivers and was outrighted to Syracuse after being designated for assignment over the weekend.
Manager Buck Showalter told the team’s beat that Carrasco will head back to New York to undergo imaging (relayed by Tim Healey of Newsday). It’s not yet clear what the issue is or how severe it might be, but it’s a concerning development for a 36-year-old pitcher. Carrasco has spent time on the IL in each of his first three seasons as a Met. He lost a chunk of the first half in 2021 to a hamstring strain and missed a bit of time last year with an oblique issue. He’s generally avoided elbow concerns in recent years, though he did undergo Tommy John surgery over a decade ago while playing for Cleveland.
The start to the season hasn’t gone well for the veteran righty. He’s been tagged for 13 runs in 13 2/3 innings over his first three starts. Carrasco has eight strikeouts and walks apiece and has already surrendered a trio of home runs. He’s also battled a velocity dip. Carrasco’s average fastball speed has checked in at 91.3 MPH; that’s down nearly two ticks from last season’s 93.2 MPH average. He certainly hasn’t appeared to be at full strength and the IL stint reflects that.
Carrasco joins Justin Verlander and José Quintana as expected rotation members on the shelf. Quintana won’t be back until midseason but Verlander should be able to make his team debut before too long. Verlander is tentatively scheduled to throw a live batting practice session on Sunday, tweets Anthony DiComo of MLB.com. He’ll be on a five-day throwing program from that point, with a minor league rehab start the anticipated next step. That points towards a potential MLB return in the first week of May if all goes as planned.
In the meantime, the Mets will have to plug another rotation vacancy. Injuries to Verlander and Quintana forced the team to call upon David Peterson and Tylor Megill. The likes of José Butto and Joey Lucchesi project as the next line of defense. Butto was already called up for a spot start against the A’s over the weekend. He was promptly optioned out and has to spend 15 days in the minors unless he’s replacing someone who lands on the IL. Considering he wasn’t the corresponding promotion with Carrasco’s placement, that might point towards Lucchesi getting a call later this week.
Santana lost his roster spot as part of the shuffling to accommodate Butto’s promotion last Saturday. The sinkerballer has bounced around via trade or on waivers since the start of the offseason. He’d made seven appearances for the Mets this year, allowing six runs over 7 2/3 frames. Santana has over three years of major league service time and has the right to refuse an outright assignment. Doing so would require forfeiting his $1MM salary, however, so it’s likely he’ll report to Syracuse and try to pitch his way back onto the MLB radar. He’d reach minor league free agency at season’s end if he’s not first added to the 40-man roster.
Lack Of Offense Puts Royals In An Early-Season Hole
The Royals entered 2023 in a tricky spot. They’ve already rebuilt but haven’t progressed to the point where the organization and its fanbase had surely envisioned. While Kansas City went into last year as a dark horse pick to hang in the Wild Card mix, they stumbled to a 65-97 record that led to changes at the top of baseball operations and in the manager’s office.
Kansas City had a relatively quiet offseason. They added Jordan Lyles, Ryan Yarbrough and Aroldis Chapman while retaining Zack Greinke, looking for veteran stability on a pitching staff that hasn’t gotten expected contributions from a handful of highly-regarded young arms. The offseason attention on the pitching staff apparently left little room in the budget to attack an offense that ranked 24th in the majors in run scoring.
Franmil Reyes, Jackie Bradley Jr. and Matt Duffy — each of whom broke camp after signing minor league contracts — are the only new faces in the Royals’ position player group. (K.C. also shipped out center fielder Michael A. Taylor to the Twins.) While it’s still very early, the Royals are feeling the effects of that lack of offseason attention to the lineup.
Entering play Tuesday, the Royals sit 28th in the majors in runs scored (54). They’re dead last in all three triple slash stats with a .202/.264/.326 team batting line. Only the Giants have a higher strikeout rate than Kansas City’s 26.5% clip and they’re 25th in walk percentage. With that kind of offense, it’s not a surprise the Royals have been outscored by 32 runs and limped to a 4-13 start.
As one would expect given the extent of their struggles, the Royals aren’t getting much production virtually anywhere in the lineup. Duffy has been solid in a limited role. First baseman Vinnie Pasquantino has been excellent and is somewhat quietly making a case for himself as one of the sport’s best young hitters. Shortstop Bobby Witt Jr. has been adequate. Beyond that trio, the offense has been almost completely unproductive.
Ten of the 13 Kansas City hitters with 20+ plate appearances are off to below-average starts. The second base/third base duo of Michael Massey and Hunter Dozier hasn’t hit. Things have arguably been even more worrisome on the grass. Royals’ outfielders are hitting .178/.241/.256 over 195 combined trips to the dish. That’s the worst output in the league by a wide margin; the second-worst start by an outfield, by measure of wRC+, is the .207/.263/.337 production from the Diamondbacks’ group.
Outfield was a major question mark for K.C. heading into the year. It’s a group comprised mainly of players in their mid-20s who haven’t yet established themselves at the MLB level. Catcher/outfielder MJ Melendez has power but questions about his swing-and-miss and his best defensive fit. Edward Olivares has paired interesting physical tools with an aggressive approach resulting in a meager .302 career on-base percentage. It’s a similar story with Kyle Isbel, who has been productive in the upper minors but not yet translated that against big league pitching. Nate Eaton had a big 2022 season in Triple-A; he’s already 26 and was never an especially highly-regarded prospect though.
Drew Waters, who has been on the shelf all season with a left oblique strain, has power and an excellent defensive profile but concerns about his strikeout totals. Bradley and Reyes have been very good MLB players in the past but fallen on hard times offensively in the last couple seasons.
It’s too early in the season to write off any specific player, particularly the younger options who have gotten scattershot playing time over the past couple years. As a collective, however, it’s an unencouraging start. Even if someone like Melendez or Olivares takes a step forward, the overall outfield looks like a below-average group. Perhaps 2022 first-round pick Gavin Cross can solidify a spot in the long run, but the Virginia Tech product is still in High-A and looks unlikely to be an MLB factor this year.
The Royals’ offense assuredly won’t be this bad all season. Salvador Perez is going to snap out of an early-season rut. Witt should post a better line than his current .262/.314/.415 mark. There’s essentially nowhere for the outfield to go but up. Yet even with some amount of forthcoming positive regression, it’s hard to see the Royals climbing back towards competitiveness. They entered the season as a projected bottom five to ten team at FanGraphs and Baseball Prospectus. They’ve promptly dug themselves a nine-game hole just to get back to .500. Despite playing in one of the game’s weaker divisions, the Royals are trending towards deadline sellers.
We’re not yet at that point. General manager J.J. Picollo and his front office are unlikely to consider any serious roster subtractions before late June at the earliest. Barring a dramatic reversal of fortunes in the next two months, though, there’s likely to be a fair amount of deadline chatter about possible trade candidates on the K.C. roster. Closer Scott Barlow is off to a rough start but would draw plenty of interest if he can rediscover his 2021-22 form, particularly with an extra season of arbitration control. The Chapman signing has looked good in the first couple weeks, as the fireballing lefty has punched out 12 of 22 opposing hitters. He’s an obvious midseason trade candidate as a one-year free agent pickup. Starter Brad Keller and lefty reliever Amir Garrett are impending free agents off to decent starts.
The coming months will determine how many of those players change uniforms midseason. The club’s lack of hitting through the year’s first three weeks has put them behind the eight ball if they’re to avoid trading veterans who are getting closer to the open market.
Dodgers Select Luke Williams, Transfer Daniel Hudson To 60-Day IL
The Dodgers announced they’ve selected the contract of utility player Luke Williams. He’ll take the active roster spot of infielder/outfielder Mookie Betts, who has been placed on the paternity list. To open a spot for Williams on the 40-man roster, right-hander Daniel Hudson was transferred to the 60-day injured list. Jack Harris of the Los Angeles Times reported that Williams was with the club prior to the official announcement.
Williams could be in position to make his team debut. Initially claimed off waivers from the Marlins at the start of last offseason, he was promptly non-tendered. The Dodgers circled back to re-sign him to a minor league deal, assigning him to Triple-A Oklahoma City to open the year. The right-handed hitter has been on a tear through his first couple weeks in OKC, hitting .375/.455/.696 with seven walks and only ten strikeouts through 66 plate appearances.
Initially a third-round pick of the Phillies, Williams has briefly appeared for three teams at the MLB level. He’s a .240/.299/.316 hitter across 244 big league plate appearances. He’s up to a more impressive .307/.378/.455 line in 60 Triple-A contests split through a trio of seasons. Williams brings a fair bit of defensive flexibility to the bench, as he has ample experience at the three infield spots to the left of first base and each outfield position.
That versatility takes on some immediate importance in L.A., as Chris Taylor has been bothered by side soreness. The utilityman told reporters he’s not scheduled for imaging and hopes he can avoid an injured list stint (via Fabian Ardaya of the Athletic). He’s out of tonight’s game though, thinning the depth behind Miguel Rojas at shortstop.
It seems Betts could factor into that mix as well. He’s expected to rejoin the team tomorrow — Williams still has a pair of minor league options and could easily be sent back to Oklahoma City — and skipper Dave Roberts implied Betts could get some starts at shortstop (relayed by Juan Toribio of MLB.com). Betts has never started a professional game at shortstop, so it’s unlikely he’ll offer the plus defense there that Rojas provides. Betts has experience at second base, however, and he’s obviously a far better hitter than Rojas. The glove-first veteran is off to a meager .129/.182/.161 start to his Dodger tenure.
As for Hudson, he’s now officially ruled out through late May. The IL placement backdates to the start of the regular season. The veteran reliever has been delayed by left knee soreness as he works back from last season’s ACL tear. Roberts said today that Hudson has battled patellar tenditis in the joint. The Dodgers are targeting a June return, so there’s little reason not to place him on the 60-day IL (Ardaya link).
Jeffrey Springs Expected To Have Tommy John Surgery
Rays left-hander Jeffrey Springs is expected to have Tommy John surgery, reports Marc Topkin of the Tampa Bay Times. That will put an end to his 2023 campaign and cause him to miss the start of the 2024 season as well. Earlier today, the club had placed him on the 15-day injured list with right-hander Taj Bradley recalled to take his place on the roster.
The news comes as a devastating blow to what had previously been a feel-good story. Springs, 30, was a 30th round draft pick of the Rangers and didn’t draw a lot of fanfare as a prospect. He got to the big leagues with Texas in 2018 and 2019, but posted an uninspiring 4.90 ERA through his first 64 1/3 innings. He was traded to the Red Sox but then put up a 7.08 ERA in the shortened 2020 season.
A trade to the Rays seemed to turn things around for him. He made 43 appearances in 2021 with a 3.43 ERA, 35.2% strikeout rate, 7.8% walk rate and 34.3% ground ball rate. Last year, the club gradually stretched him out to a starter’s workload over the course of the season. He eventually posted a 2.46 ERA in 135 1/3 innings, striking out 26.2% of batters faced while walking just 5.6% and getting grounders on 40.9% of balls in play. The Rays believed in that breakout enough to give the southpaw a four-year extension with a $31MM guarantee and plenty of incentives.
He was looking to build off that breakout campaign and was off to a strong start here in 2023. He had already tossed 16 innings with a tiny 0.56 ERA, though that will now seemingly go down as the entirety of his work this year. Rehab from Tommy John surgery typically takes 14 months or longer, meaning Springs won’t be an option for the club until midway through 2024 at the earliest.
The Rays had started the season with a strong rotation, even though there were a few injuries of note. Shane Baz had his own Tommy John surgery late last year and will likely miss all of the 2023 season. Tyler Glasnow also suffered an oblique strain in the spring and has yet to make his season debut. But Springs, Shane McClanahan, Drew Rasmussen, Zach Eflin and Josh Fleming formed a solid front five, helping the Rays jump out to a 13-0 start and a current 14-3 record.
Now the club will have to navigate the rest of the season without Springs. Eflin is also on the injured list but is expected to be back this weekend after a minimum stay. Bradley made his MLB debut in a spot start for the club last week and will now seemingly get a longer audition to stick around.
Nationals Release Yadiel Hernandez
The Nationals released outfielder Yadiel Hernandez on Monday, per the transactions log at MiLB.com. He’d opened the season as a non-roster player with their Triple-A club but was cut loose after a .205/.225/.256 start to his season through a small sample of 40 plate appearances.
The 35-year-old Hernandez was a regular presence in the Nationals’ lineup from 2021-22, logging a combined 616 plate appearances while batting .271/.320/.411 with 18 home runs, 24 doubles, a triple and five steals (in six tries). Hernandez wasn’t a well-rated defender in the outfield corners but was a roughly league-average bat (100 wRC+) who lacked glaring platoon splits; he hit fellow lefties slightly better than righties during his time with the Nats. Washington designated Hernandez for assignment when setting its roster ahead of 2022’s Rule 5 Draft and successfully passed him through outright waivers.
Hernandez didn’t make his Major League debut until 2020, having spent the bulk of his prime years playing professionally in Cuba, where he was a lifetime .324/.450/.487 batter in 2167 plate appearances for los Cocodrilos de Matanzas. Hernandez defected from Cuba in 2015 but wasn’t declared a Major League free agent until 2016. He signed for a $200K bonus with the Nats late in the ’16 season and spent the 2017-19 seasons between Double-A and Triple-A.
In a total of 1564 minor league plate appearances, all coming between Double-A and Triple-A, he’s a .298/.379/.499 hitter with 68 home runs, 65 doubles and three triples. Given his age, slow start in Rochester this season and relatively limited big league track record, Hernandez isn’t likely to jump right onto an MLB roster but could be a candidate for a minor league deal with another team in need of outfield depth or perhaps could garner some interest abroad.
Athletics To Promote Mason Miller
The Athletics are planning to promote pitching prospect Mason Miller, reports Matt Kawahara of the San Francisco Chronicle. It seems possible that Miller will join the team today and could make his major league debut tomorrow. He’s not yet on the 40-man roster and will require a corresponding move.
Miller, 24, was selected by the A’s in the third round of the 2021 draft, making his professional debut with a few Complex League outings shortly after that draft. He logged just six innings there, but Baseball America ranked him the #16 prospect in the system going into 2022, largely based on his work in college. He was then limited by a shoulder strain in 2022, not making his season debut until late August. He made one appearance in the Complex League, three in High-A and then two in Triple-A. He finished the year with a combined 3.86 ERA in 14 innings over those games.
It was a very limited sample, but he did rack up 25 strikeouts, exactly half of the 50 batters he faced, while keeping his walks down to a 6% rate. He was then sent to get some extra work in the Arizona Fall League, tossing 16 2/3 innings there with a 3.24 ERA, racking up another 20 punchouts. Based on that strong-but-limited showing, BA bumped him to #4 in the system coming into this year. FanGraphs was perhaps even more bullish, giving Miller the #98 spot on their preseason list of the top 100 prospects in the league. Both outlets highlight Miller’s velocity, with his fastball able to hit triple digits, while also complimenting his slider and changeup. BA adds that he was planning to re-introduce a cutter in 2023, a pitch he had been avoiding as part of his rehab.
This year, Miller started out with a Double-A appearance, allowing two earned runs over 3 2/3 innings, but striking out eight opponents. He then got bumped to Triple-A, where he tossed five shutout innings with 11 punchies. By all accounts, Miller clearly has electric stuff and great results, but in very small samples. His entire professional career consists of 28 2/3 innings in the minors and those 16 2/3 frames in the AFL, adding up to 45 1/3. He did log 239 innings in college, but it’s still unusual for a club to fast-forward a player’s rise through the minors like this. That being said, Miller seems to have excellent stuff and might be ready to get big league hitters out right now.
The A’s have been toying with using a six-man rotation this year, in part to help Shintaro Fujinami adjust from the once-a-week pitching schedule preferred in Japan to the five-day rotation that’s more common in North America. He’s been joined by Kyle Muller, JP Sears, James Kaprielian, Ken Waldichuk and Adam Oller so far, though Oller made two long relief outings before getting his first start of the year last week. He was rocked for seven earned runs in just 2 1/3 innings in that start and was optioned to the minors shortly after. It seems his struggles have perhaps opened an opportunity for Miller to make his MLB debut. The A’s weren’t expected to compete this year and are off to a 3-14 start, giving them little reason not to see what they have in Miller.
Now that Opening Day has moved into the rearview mirror, it won’t be possible for Miller to reach a full year of service time. A baseball season is 187 days long but a player needs just 172 days on the active roster or injured list to accrue a full year. With the season now 20 days in, Miller would come up just shy of that one year mark even if he stays up for good. The new collective bargaining agreement has a path for players to get a full year of service time anyway, though that only applies to those who cracked two of the preseason top 100 lists at Baseball America, MLB Pipeline or ESPN. Miller made the FanGraphs list but none of those other three, meaning he doesn’t have a path to a full service year in 2023.

Brewers Claim J.B. Bukauskas From Mariners
The Mariners announced that right-hander J.B. Bukauskas has been claimed off waivers by the Brewers. The M’s had designated him for assignment last week. To make room for Bukauskas on their 40-man roster, the Brewers have transferred infielder Luis Urías to the 60-day injured list, per Todd Rosiak of the Milwaukee Journal Sentinel. Bukauskas has been assigned to Triple-A Nashville, per Rosiak.
Now 26 years old, Bukauskas was the No. 15 overall pick by the Astros back in 2017. The ‘Stros traded him to the D-backs as part of the four-prospect package that brought Zack Greinke to Houston, but Bukauskas battled injuries and never got much of a big league look in Arizona. The Diamondbacks gave him just 17 1/3 innings in the Majors, during which time he was tagged for 15 earned runs on 24 hits and seven walks with 14 strikeouts.
A flexor strain in 2021 and a teres major strain in 2022 limited Bukauskas to just 52 1/3 innings combined between those two seasons. The Diamondbacks designated him for assignment back in January when opening a roster spot for the re-signing of Zach Davies, at which point the Mariners claimed him. Seattle successfully passed him through outright waivers a few weeks later but selected Bukauskas back to the big league roster early in the season when Andres Munoz hit the injured list.
While he’s had a rough start to his season, Bukauskas posted strong Triple-A numbers in a small sample of 20 1/3 innings last year. Overall, he carries a 3.96 ERA, 26.3% strikeout rate and 6.9% walk rate in 38 2/3 innings at that level. Bukauskas has averaged 94.5 mph on his four-seamer in the big leagues, and in his lone look with the Mariners this year he was relying on a sinker in place of that four-seamer. Dating back to his prospect days, he was touted for a plus or better changeup. He’s in his final minor league option year, so if he sticks on Milwaukee’s roster, he can give them some flexible bullpen depth for the remainder of the season.
Braves Claim Nick Solak From White Sox
The Braves announced that they have claimed infielder/outfielder Nick Solak off waivers from the White Sox and optioned him to Triple-A. The latter club had designated him for assignment on the weekend. Atlanta had an open roster spot due to losing left-hander Richard Lovelady off waivers to the Athletics last week.
Solak, 28, has spent the past four seasons in the Rangers organization. Once regarded as a polished bat with a questionable defensive outlook, the former second-round pick hit .293/.393/.491 in 135 plate appearances as a rookie in 2019 but hasn’t found much success at the plate since.
Dating back to 2020, Solak is a .246/.317/.354 hitter in 839 trips to the plate. He’s spent the bulk of his time in the Majors at second base but also has experience in left field (324 innings), in center field (108 innings) and at third base (97 innings). Defensive metrics have panned his glovework at all four spots, however.
Solak may not have much big league success, but he has a sharp .289/.369/.503 batting line in parts of four Triple-A seasons, has played multiple infield and outfield positions, and has a minor league option remaining. That’s caused him to bounce around the league this year, as several clubs have picked him up since his original DFA with the Rangers in hopes of being able to pass him through waivers themselves, thus retaining Solak as a non-roster depth option in Triple-A.
Texas initially traded Solak to Cincinnati in exchange for cash back in November. When the Reds designated him for assignment in late March, the Mariners sent cash to the Reds to acquire Solak. Current outright waiver priority is still dependent on last year’s regular-season standings and, contrary to popular belief, is not league-specific. (That only applied to now-defunct August trade waivers.) As such, Solak falling to Atlanta means that the vast majority of the league passed on him, with only the Astros and Dodgers having lower priority than the Braves at present. Atlanta could well try to pass Solak through waivers in the coming days, but for now he’ll head to Gwinnett and hope to play his way into an opportunity on the big league roster.
MLB To Experiment With Designated Pinch Runner In 2023 Atlantic League Season
Major League Baseball announced today that it will experiment with various rule changes in the Atlantic League this season, which begins April 28. Since 2019, the Atlantic League and MLB have had a partnership whereby the latter uses the former to test out rule changes before they are brought to the majors, with the general goal being a better pace of play and more game action.
This year’s season will be testing the following rules, with direct wording from the MLB release:
- New to the Atlantic League this season will be the use of a Designated Pinch Runner. Each club will list a player who is not otherwise in the starting lineup as a designated pinch runner. That player may then be substituted at any point into the game as a baserunner. The player who is substituted for, as well as the pinch runner, may then return to the game without penalty.
- Unlike the new MLB rule which allows a pitcher to disengage from the pitching rubber twice during an at-bat, the Atlantic League will permit only a single disengagement per at-bat in 2023.
- The ALPB will continue the use of the “Double-Hook” DH rule, which allows clubs to use the designated hitter throughout the game provided that the club’s starting pitcher has completed at least five innings. If the starter fails to make it through the fifth, the club then loses the DH for the remainder of the game.
Of these three changes, the first one is clearly the most significant. The “Double-Hook” rule is not in place in the majors, but was previously attempted in the Atlantic League in 2021. Initially, a team would lose its designated hitter as soon as the starter was removed from the game. Last year, that was modified so that a team could keep its DH if the starter lasted five innings, with that modification continuing into 2023. The goal here seems to discourage creative pitcher usage, such as deploying openers or bullpen games. This would also increase the importance of strong starting pitching, something that has waned with time as teams rely more and more on relievers to finish games. Even if this rule were to ultimate make it to the major leagues, it wouldn’t be a drastic change, as it would simply revert certain teams to pre-DH rules on a temporary basis. The universal DH only became permanent a year ago with the new Collective Bargaining Agreement.
The disengagement rule is already in place at the major league level, with this just being a slight modification of it. The goal there is to increase action by having more base stealing attempts. Along those same lines, we have this new designated runner rule. It’s easy to see how this would lead to increased action on the bases, with the league having many players who can hit but who lack speed, or vice versa. Pinch running is obviously not new to baseball, but it has traditionally involved the removed runner also being removed from the game entirely. This new rule would allow a pinch running specialist to repeatedly ply their trade throughout the game, whereas a slower player could be removed early in a game but continue to hold their place in the lineup.
Like all proposed rule changes, the intended goals will be tested to see if they actually work, while many will debate whether the changes are worth it. Some baseball fans are resistant to any change whatsoever, while even some who don’t consider themselves traditionalists might still have problems with certain proposals.
It’s worth stating that it’s not a given that a rule tested in the Atlantic League will inevitably make it to the majors. Some changes have made the jump, including the three-batter minimum for pitchers, the bigger bases, defensive shift restrictions and others. But there are also changes that were tried and ultimately abandoned, such as moving the pitching rubber back one foot.
