Emerson Hancock

Mariners Recall Emerson Hancock, DFA Seby Zavala

By | at

The Mariners have promoted right-handed pitcher Emerson Hancock from Triple-A, the team announced this afternoon. To make room on the active roster, Seattle designated catcher Seby Zavala for assignment.

Hancock will take the ball this evening against the Rangers, filling in for an injured Luis Castillo. Castillo landed on the 15-day IL with a Grade 2 left hamstring strain following his start last Sunday. After officially placing Castillo on the IL on Tuesday, the Mariners did not need to add another starting pitcher to the active roster until today, so they selected Zavala’s contract instead. He did not appear in a game. Presuming Zavala passes through waivers, he will most likely accept an outright assignment to Triple-A Tacoma, considering the Mariners have already outrighted him twice this season. Indeed, this is the second time Seattle has DFA’d Zavala to make room for Hancock on the major league roster.

The 25-year-old Hancock is back for his fourth stint with the big league club this season. Over nine starts, he has pitched to a disappointing 4.76 ERA and 5.14 SIERA in 45 1/3 innings pitched. Unfortunately, the young right-hander hasn’t looked much better at Triple-A. He has a 4.66 ERA and 5.78 FIP in 10 starts (56 IP) since his most recent demotion. As was his biggest problem last year, he has had tremendous difficulty earning strikeouts against Triple-A and MLB competition, and he isn’t limiting walks or hard contact as much as needs to if he’s going to survive with such a low strikeout rate.

Hancock still has all the potential that made him one of the Mariners’ top pitching prospects from the moment he was selected with the sixth overall pick in 2020 to his graduation from prospect status this season. However, he has yet to turn that potential into results. Presumably, he’ll get a couple more chances to prove himself in the majors this season while Castillo is on the IL.

Zavala, 31, came to the Mariners last November as part of the trade that sent Eugenio Suárez to the Diamondbacks. He is a strong defensive catcher thanks to above-average framing and blocking skills, but his career .205/.271/.342 slash line is precisely why he has been unable to hold down a job in the majors this season. It hasn’t helped that he is 19-for-101 (.188) with a 79 wRC+ at Triple-A this year. Presumably, he will finish the season at Triple-A Tacoma, sticking around as additional catching depth in case one of Cal Raleigh or Mitch Garver suffers a late-season injury.

Mariners Designate Seby Zavala For Assignment

By | at

The Mariners announced that catcher Seby Zavala has been designated for assignment.  In the corresponding move, right-hander Emerson Hancock has been called back up from Triple-A to start today’s game against the Blue Jays.  Zavala’s DFA also creates an opening on Seattle’s 40-man roster.

This is the second time in the last three weeks that Zavala has been designated, and his previous trip to DFA limbo saw him clear waivers and then outrighted to Triple-A Tacoma.  Because Zavala had previously been outrighted in his career, he could’ve rejected that assignment and instead become a free agent, but he opted to remain with the M’s and report to Triple-A.  Zavala is out of minor league options, so Seattle has been forced to designate the catcher and thus expose him to the waiver wire in order to move him to Triple-A.

Zavala could very well pursue the same path this time around, given that the Mariners selected his contract back onto the 26-man roster in pretty short order after his previous outright.  That move (just earlier this week) came after Mitch Garver was dealing with a sore wrist, and thus the Mariners wanted some extra catching depth if Garver was strictly limited to DH duties or perhaps needed to visit the injured list.  Since Garver appears to be okay, the M’s apparently now feel comfortable enough with the situation to again remove Zavala from their 40-man.

With Cal Raleigh handling the starting catcher duties and Garver also getting some part-time work behind the plate, Zavala has gotten into just 18 games this season, and is hitting .154/.214/.282 over 43 plate appearances.  Even considering that Zavala is known as a defensive specialist, the Mariners have decided to go with the bat-first approach with their catching corps, which isn’t surprising given how Seattle has been hurting for offense all season.

As for Hancock, he is set to make his ninth start of the season after delivering a 4.79 ERA in his first 41 1/3 innings of the season.  The former top prospect has gotten another look with Bryan Woo on the 15-day IL, but since Woo is expected back relatively soon, Saturday’s outing will likely be just a spot start for Hancock.  It could also potentially be an unofficial audition for potential trade suitors, if the Mariners look to deal from their rotation depth to upgrade their lineup at the deadline.

Mariners Select Kirby Snead

By | at

The Mariners announced a series of roster moves today, selecting the contract of left-hander Kirby Snead and reinstated right-hander Eduard Bazardo from the injured list. In corresponding moves, left-hander Tayler Saucedo was placed on the 15-day IL due to right knee hyperextension and right-hander Emerson Hancock was optioned to Triple-A Tacoma. To open a 40-man spot for Snead, righty Matt Brash was transferred to the 60-day IL.

Snead, 29, signed a minor league deal with the Mariners in the winter. He reported to Triple-A and has made 12 appearances at that level so far this year with a 2.92 earned run average. That’s supported by a 27.7% strikeout rate, 4.3% walk rate and a huge 63.3% ground ball rate.

The southpaw has had some encouraging results in the minors before, but has struggled in the majors. He currently has a career ERA of 5.20 in the big leagues, tossing 64 innings over the previous three seasons between the Blue Jays and Athletics. He was outrighted by Oakland in October, which led to his deal with the Mariners.

With Saucedo going on the IL, Snead will step in as the club’s second lefty reliever alongside Gabe Speier. Snead is out of options and can’t be easily sent back down to the minors down the line. However, he has less than two years of service time and could therefore be cheaply retained into the future if he holds onto his roster spot all year.

Hancock, 25 this month, came into the year as the club’s sixth starter behind Luis Castillo, George Kirby, Logan Gilbert, Bryce Miller and Bryan Woo. But Woo began the year on the injured list due to right medial elbow inflammation, which opened a rotation spot for Hancock.

Through seven starts, Hancock has a 5.24 ERA with a tepid 15.4% strikeout rate. Woo has been on a rehab assignment of late, having already made three starts with the most recent one being a five-inning outing on Saturday. Hancock’s option appears to pave the way for Woo to be reinstated at some point in the near future.

As for Brash, he’s been on the 15-day IL all year due to right elbow inflammation. This transfer is backdated to his initial IL placement, meaning he can’t be reinstated until late May. That doesn’t seem to be a possibility anyway, as he was shut down at the end of April and there haven’t been any substantive updates on his condition since then.

Mariners Notes: Urias, Woo, Miller

By | at

Mariners infielder Luis Urias exited last night’s game after taking a 94 mph fastball of his left wrist, but the Mariners announced that he’s been diagnosed with a contusion. X-rays on the wrist were negative, per MLB.com, and he’ll be considered day-to-day for the time being.

The 26-year-old Urias has gotten out to a .160/.300/.400 start this season, striking out 11 times in 30 plate appearances (36.7%) — an uncharacteristically high rate for a player who entered the season with a career 21.6% strikeout rate.

The Mariners entered the season envisioning a platoon of the righty-swinging Urias and lefty-hitting Josh Rojas — a more contact-oriented pairing than the more boom-or-bust nature of since-traded third baseman Eugenio Suarez. Rojas has been one of the team’s bright spots, hitting .311/.392/.422 (148 wRC+) in 51 trips to the plate thus far. Only four of those plate appearances have come against lefties, but if Urias is sidelined for a bit, Rojas could get some more reps against southpaws. Seattle doesn’t have many lefty opponents on the immediate horizon, though they’re slated to face Andrew Heaney on Thursday.

Elsewhere on the injury front, the M’s are getting closer to welcoming righty Bryan Woo back to the staff. The right-hander made his first minor league rehab appearance with Triple-A Tacoma last night, and as broadcaster Mike Curto points out, pitched three perfect innings while fanning five of his nine opponents.

Woo’s fastball ranged from 91-95 mph, per Curto, which is down from last year when he averaged 95.2 mph on his heater. That said, it’s also the first rehab start for a right-hander who’s yet to pitch this season while waiting for some elbow inflammation to calm down, so that’s not necessarily a massive red flag just yet. It’d be natural if he built closer to that velocity as he continued to ramp up over what could be multiple rehab starts between now and his activation.

In place of Woo in the rotation, Seattle has been relying on former top-10 pick Emerson Hancock, who’s posted a 6.10 ERA through four starts, although the vast majority of the damage came in one tough outing against the Brewers. Hancock has yielded a combined seven earned runs through 17 1/3 innings in his other three appearances but was lit up for an eight spot in just 3 1/3 innings that day. He’s sporting a well below-average 16.7% strikeout rate but also an exceptional 3.3% walk rate. Hancock is the least established arm in Seattle’s rotation, trailing Luis Castillo, George Kirby, Logan Gilbert and Bryce Miller — so he’s likely to be the odd man out if everyone’s healthy when Woo returns.

Miller, in particular, has impressed the Mariners this year. He’s pitched to an electric 1.85 ERA with a 26.1% strikeout rate and 7.6% walk rate in 24 2/3 innings. Miller recently chatted with Adam Jude of the Seattle Times about his incorporation of a new splitter into his repertoire — a pitch that’s been flat-out dominant for the 25-year-old righty so far. Miller has thrown his new pitch at a 19.4% clip this season, finishing off 24 plate appearances with the pitch. Those 24 plate appearances have resulted in 21 outs — eight of them strikeouts — and yielded only three singles. Both Gilbert and Kirby began throwing splitters last season, and Miller has leaned on his teammates for advice and guidance when looking to master his new pitch.

“It kind of has a mind of its own sometimes, but I’ve been able to command it really well,” Miller tells Jude of his new weapon. “So, I’m really happy with it and I think it’s opened up a lot of things for me [against] lefties and righties.”

Mariners Still Exploring Infield, Bullpen Markets

By | at

It’s been an active two weeks for the Mariners, who’ve recently signed Mitch Garver to a two-year deal and shipped out Robbie Ray and Jose Caballero in trades that brought Mitch Haniger, Anthony DeSclafani and Luke Raley back to Seattle. President of baseball operations Jerry Dipoto said this weekend that while his team feels more complete now than at any point this offseason, he’s still open to subsequent additions (link via Ryan Divish of the Seattle Times).

More specifically, Ken Rosenthal of The Athletic reports that the Mariners are still hoping to acquire an infielder to make the club less reliant on the uncertain tandem of Luis Urias and Josh Rojas, who are currently projected to start at third base and second base, respectively. Seattle would also like to add a reliever, per Rosenthal, which Dipoto alluded to in his comments to Divish and others.

An infield upgrade is a sensible target for the M’s, given the volatility presented by both Urias and Rojas (and to a lesser extent, first baseman Ty France, who’s coming off a down season). From 2021-22, both Urias (.244/.340/.426, 111 wRC+) and Rojas (.266/.345/.401, 106 wRC+) were above-average performers at the plate, due in no small part to walk rates approaching 11%.

Rojas saw his walk rate drop to 7.7% in 2023, however, as he batted just .240/.303/.338 in 350 plate appearances. Urias maintained his walk rate but watched his hard-hit rate and exit velocity plummet en route to a middling .194/.337/.299 slash in 155 trips to the plate. Both players saw their strikeout rates tick up to near identical marks of 23.2% and 23.1% — slightly higher than league average but also well south of the 30%-plus rates of some names they shipped out in trades.

Both Rojas and Urias come with platoon issues of note, as well. The lefty-swinging Rojas has extremely similar rate stats against lefties and righties, with identical 93 wRC+ marks against each, but his production against lefties is contingent on a .361 average on balls in play that’s not likely to hold up. Rojas has punched out at an ugly 28.3% clip against southpaws compared to a 21% mark against righties and hit for more power when holding the platoon advantage as well (.098 ISO versus lefties, .122 versus righties). It’s the opposite for the right-handed Urias, who’s smacked southpaws at a .276/.353/.442 pace in his career but carries a .219/.326/.365 slash against right-handers.

Rojas and Urias are both capable of playing either second or third base, so there’s a potential platoon setup between the two. Alternatively, if the M’s succeed in adding a second or third baseman and prefer to go with one true starter at the other slot, both Rojas and Urias could profile as a potential utility option off the bench.

Because of the defensive flexibility the current group possesses, the Mariners could look for options at either second base or third base. Dipoto typically operates more on the trade market than on the free-agent market, though both provide myriad avenues to fill the team’s needs. Whit Merrifield stands as the top free agent at second base. The Mariners aren’t going to meet Matt Chapman’s asking price at third base, but Gio Urshela and Justin Turner would represent much more affordable alternatives. Any of that trio would meet the Mariners’ previously stated goal of improving the club’s contact rate (which hasn’t exactly been strictly adhered to, when looking at the acquisition of Raley in particular).

On the trade market, Minnesota’s Jorge Polanco is a natural target who could step in at second base (speculatively speaking, to be clear). The Twins are deep in controllable young infielders and looking to slightly scale back payroll due to the RSN collapse that’s impacting budgets around the league (including the Mariners). The switch-hitting Polanco is earning $10.5MM this season and has a $12MM option for the ’25 campaign. The Reds, Orioles, Cardinals and Guardians are also deep in infield talent and could be intrigued by Seattle’s stock of young arms. That said, Dipoto cast significant doubt on his willingness to move a controllable starting pitcher with his weekend comments.

“We did a lot of groundwork on what it might look like if we did trade one of those young starters, and we never liked the way it looked,” Dipoto said (via Divish). He called retaining his stock of young arms (e.g. Logan Gilbert, George Kirby, Bryce Miller, Bryan Woo, Emerson Hancock) “Plan A” this offseason.

Within that same media session, Dipoto maintained an openness to further additions to the roster, speculatively rattling off the possibility of making “a fun addition in the bullpen” or more generally “an upgrade somewhere on the field that we don’t really have.” The Mariners have an imposing late-inning trio of Andres Munoz, Matt Brash and Justin Topa, but they’re relatively light on lefty options — with 28-year-old Gabe Speier and 30-year-old Tayler Saucedo as the only options on the 40-man roster. Both were solid in 2023, but neither had found any real MLB success prior to last season.

Dipoto has said previously that the Mariners’ 2024 payroll could increase over its 2023 levels, although a substantial increase hasn’t looked likely all winter. Ownership has rather clearly placed some fiscal constraints on Dipoto, GM Justin Hollander and the rest of the front office, as they’re among the many teams in the game facing financial uncertainty due to their own RSN situation.

Roster Resource currently projects a payroll of around $132MM for the Mariners, which sits about $8MM shy of last year’s end-of-season mark. Divish writes within his column that the Mariners want to leave some wiggle room for in-season additions, but there’s of course still some room beneath last year’s budget and the possibility that additional trades could further alter the current payroll outlook.

Mariners Sign Luke Weaver To Major League Deal, Transfer Emerson Hancock To 60-Day IL

By | at

The Mariners announced a series of roster moves today, reinstating right-hander Bryan Woo from the injured list and signing righty Luke Weaver to a major league deal. To open two active roster spots, they optioned righties Eduard Bazardo and Darren McCaughan. To open a 40-man spot for Weaver, righty Emerson Hancock has been transferred to the 60-day injured list.

It’s a belated birthday present for Weaver, who just turned 30 years old yesterday. He was recently released by the Reds, who had signed him to a one-year, $2MM deal in the offseason. Unfortunately, his 21 starts for Cincinnati resulted in him allowing 6.87 earned runs per nine innings. His 7.6% walk rate was solid but he only struck out 19% of batters faced. Home runs were a particular problem as he allowed 24 balls to sail over the fence in that time, easily a career high for him.

The Mariners were planning to utilize a six-man rotation when Woo returned from the injured list, joining Hancock, Luis Castillo, George Kirby, Logan Gilbert and Bryce Miller, but Hancock’s injury threw a wrench in those plans. He landed on the injured list yesterday due to a shoulder strain and it seems the club isn’t expecting him back soon. Today’s transfer makes him officially ineligible to return until the middle of October. His season is now effectively over unless the club goes on a World Series run and he gets healthy enough in the next two months to put himself in position to rejoin the roster. Daniel Kramer of MLB.com reports that his recovery will take at least four to six weeks.

The club could simply go with a five-man rotation, though there are reasons why they might still prefer six. Both Miller and Woo are rookies who are pushing towards uncharted territory in terms of innings pitched in a season. Last year was Miller’s first full professional season and he was able to toss 133 2/3 frames. This year, between the majors and minors, he’s up to 117 1/3 already. Woo, meanwhile, tossed 67 2/3 last year and is already up to 99 innings this year between Double-A and the majors. Kirby was a rookie last year and logged 130 major league innings plus another 26 2/3 in the minors, and is at 150 2/3 this year.

Going with a six-man rotation would soften some of the workload concerns and the potential for fatigue down the stretch. Perhaps that is why they have brought Weaver aboard. Though his results haven’t been good this year, a change of venue would likely help him to some degree. Looking at Statcast’s park factors, the Mariners have one of the more pitching-friendly home parks while the Reds are on the other end of the spectrum, especially when it comes to home runs.

It’s also possible that the Mariners are planning to implement Weaver out of the bullpen, a role in which he’s showed some encouraging signs in the past. With the Diamondbacks and Royals last year, he had an ERA of 6.56 overall, but that included one start in which he allowed nine earned runs. As a reliever, he had a 4.78 ERA and may have deserved even better. He had a 21.7% strikeout rate, 7.9% walk rate, 40.4% ground ball rate and didn’t surrender a home run at all. But a .404 batting average on balls in play and 64.9% strand rate pushed some extra runs across the plate, with his 2.46 FIP suggesting he was perhaps better than his ERA would indicate.

Regardless of his role, it’s a low-risk move for the M’s financially. Since the Reds released Weaver, they remain on the hook for what’s left of his $2MM salary, while the Mariners will only have to pay him the prorated league minimum for any time spent on the roster. That amount will be subtracted from what the Reds pay.

Mariners Place Emerson Hancock On Injured List

By | at

2:17pm: The Mariners announced that Hancock has been placed on the 15-day IL due to a shoulder strain. A timeline hasn’t yet been provided. Seattle has also reinstated shortstop J.P. Crawford from the injured list, recalled righty Darren McCaughan from Triple-A Tacoma and optioned infielder/outfielder Sam Haggerty to Tacoma.

12:20pm: Mariners righty Emerson Hancock left yesterday’s game — just the third start of his big league career — after two shutout innings due to what the team announced as a right shoulder strain. Ryan Divish of the Seattle Times writes that Hancock is likely headed to the injured list with a lat injury of some degree. The team hasn’t yet formally announced that move.

Hancock, 24, looked like he was breezing through his first two innings, holding the Astros scoreless and yielding just two hits with two strikeouts on 31 pitches. Manager Scott Servais told Divish and others after the game that Hancock felt something “grab” in his shoulder/lat during that second frame, however.

An injury to Hancock all but derails the Mariners’ plans to move to a six-man rotation before the arrangement ever got underway. Right-hander Bryan Woo is expected to return from the injured list this week, but his activation will now simply push Seattle back to five starters. He’ll join Luis Castillo, George Kirby, Logan Gilbert and Bryce Miller in Servais’ starting five.

The advent of a six-man rotation might have allowed the Mariners to more organically manage the workloads of young starters like Hancock, Kirby, Miller and Woo. The Mariners could still go the six-man route if they’re comfortable giving regular starts to righty Adam Oller or journeyman left-hander Tommy Milone down the stretch, but it’s not clear whether either of those scenarios is under consideration.

An injury to Hancock at this stage of the season is rather ill-timed. The former No. 6 overall draft pick (2020) was just getting his feet wet in the Majors, and he’d also only recently surpassed his total workload from the 2022 season. Hancock has thrown a career-high 110 innings this year, and the Mariners surely hoped to push that number a bit further in hopes of building him up for a larger workload in subsequent seasons. They may still get that chance, depending on the severity of the injury in question, but even a minimal stay on the injured list would sideline Hancock into early September and cost him a couple of starts.

The Mariners’ success in 2023 is largely attributable to both the quality and depth of their starting pitching staff. Seattle starters rank sixth in the Majors with a 3.86 ERA and are one of just three teams with 700-plus innings from their rotation at present, trailing only the Twins and Astros in that regard — and each by a margin of two or fewer innings. Had Hancock not incurred this injury, Mariners starters may well lead the big leagues in innings pitched.

Assuming the IL stint indeed goes through, Hancock will join southpaws Robbie Ray and Marco Gonzales on the shelf. Woo is also on the IL at the moment, though the expectation has been that he’ll return this week.

The Mariners have been baseball’s hottest team this month, churning out 14 wins against four losses. That follows up a similarly hot July, where their 17 wins were tied for the most in baseball. Dating back to July 1, the Mariners have played at an outstanding 31-13 clip. They’re now in possession of the third and final AL Wild Card spot and sit just three games back of the division lead in an increasingly tight AL West race.

West Notes: Kinley, Hancock, Hudson

By | at

Rockies right-hander Tyler Kinley was placed on the 15-day injured list with right elbow inflammation earlier today, as noted by Luke Zahlmann of the Denver Gazette. While additional details of Kinley’s injury and his timetable for return are currently unclear, it’s a devastating blow for the 32-year-old righty, who made just seven appearances this season after working his way back from elbow surgery, which he underwent last June. Prior to his surgery, Kinley appeared to be something of a revelation out of the Rockies’ bullpen last year, with a dazzling 0.75 ERA, 1.74 FIP, and a 27% strikeout rate in 25 appearances with Colorado in 2022.

That strong showing led the club to extend Kinley last November with a contract that guaranteed him $6.25MM over the 2023-25 seasons. Now, it seems likely that the first of those seasons, at least, will bear little fruit. In his seven trips to the mound this season, Kinley struggled badly to a 9.53 ERA with two home runs allowed in 5 1/3 innings, though that of course is a small sample size immediately following a significant layoff from big league action. With the 2023 campaign already essentially lost for the 48-75 Rockies, the club’s top priority regarding Kinley seems likely to be ensuring he’s fully healthy and ready to go for the 2024 campaign.

More from around MLB’s West divisions…

  • Mariners right-hander Emerson Hancock exited today’s start against the Astros after just 31 pitches with a right shoulder strain, per a club announcement. While the club has not yet indicated whether Hancock will require a trip to the injured list, that seems to be the most likely outcome. After all, the 24-year-old Hancock is just three starts into his big league career and has already eclipsed his previous career-high for total innings with 110 frames of work between the majors and minors this season. If Hancock does require a trip to the shelf, the Mariners are well-equipped to weather the injury with fellow youngster Bryan Woo expected to be activated from the injured list later this week.
  • Dodgers right-hander Daniel Hudson has managed just three innings of work this season thanks to first a torn ACL and then a sprained MCL, but the veteran hurler tells Bill Plunkett of the Orange County Register that he’s hopeful he can return to the Dodgers in time to be part of the club’s postseason bullpen. If that comes to pass, Hudson would surely provide a boost to the relief corps in LA. While Dodgers relievers rank 10th in the majors with a solid 3.85 ERA, the club’s bullpen has also handled the third-most innings of work in the NL this year, leaving them potentially vulnerable to losing steam as the season heads toward the stretch run. While Hudson seems focused on a comeback attempt this year, the 36-year-old also acknowledged that he’s contemplating the end of his playing days, noting that he’s “been in pretty consistent pain for about 15 months.” With that being said, Hudson ultimately was noncommittal on his plans post-2023, saying, “…maybe I give it another shot. If not, I’ve had a pretty good run and it is what it is at that point.”

Mariners Planning To Use a Six-Man Rotation

By | at

At some point in the coming days, the Mariners are planning to shift to a six-man rotation, president of baseball operations Jerry Dipoto told Adam Jude of The Seattle Times. Despite season-ending injuries to Robbie Ray, Marco Gonzales, and Easton McGee, the Mariners boast one of the deepest rotations in baseball. As Dipoto put it, “Our one through six in the starting rotation … can pitch with anybody in the league.” That being said, most of Seattle’s starting pitchers are young and inexperienced; in other words, they could benefit from some extra rest.

The current starting five consists of Luis Castillo, George Kirby, Bryce Miller, Logan Gilbert, and Emerson Hancock. Bryan Woo is expected to return from the injured list and rejoin the rotation early next week (Twitter link). Of those six, only Castillo and Gilbert had pitched a full major league season before this year. Miller, Hancock, and Woo are rookies, while Kirby, still just 25 years old, is on pace to pitch his first qualified season. He threw 130 innings last year in his rookie campaign.

As Jude reports, the Mariners plan to go with a six-man rotation once Woo comes back from the IL. He could have supplanted Hancock, who has struggled in his first two big league starts (5.40 ERA, 9.8% strikeout rate), but it seems Seattle is comfortable giving the top prospect a longer leash. However, Dipoto did mention that the team might “piggyback” Woo and Hancock down the stretch after trying out a six-man rotation for a week or two.

Additional rest will be most beneficial for Seattle’s young arms, but it should help the rest of the rotation, too. Castillo has been one of the more durable starters in baseball over the last six years, making 158 starts with a 3.58 ERA. Only six pitchers have thrown more innings in that time, so he could certainly use some time off. The same goes for Gilbert, who had thrown 338 2/3 big league innings before his 26th birthday. Since making his debut in 2021, he ranks tenth in the majors in starts and 15th in innings pitched. Dipoto acknowledged that Castillo, Gilbert, and Kirby will have to shoulder plenty of responsibility should the Mariners make the playoffs, and some extra rest now should help them stay fresh for a potential postseason run.

However, while this arrangement will benefit everyone in the rotation, it will make things harder on the bullpen. If the Mariners carry six starting pitchers, they will only have room for seven relievers on the 26-man roster. Furthermore, it’s not as if Seattle’s young starters have been pitching especially deep into games. Woo and Hancock are averaging exactly five innings per start, while Miller is averaging five and a third. Castillo, Kirby, and Gilbert are averaging about six innings per start, but those three will pitch less often with a six-man rotation. Thus, the bullpen will have a heavier load to carry for as long as the six-man rotation experiment lasts.

Thankfully for Seattle, they have one of the best bullpens in baseball. Mariners relievers rank second in ERA and third in FanGraphs WAR, and they’ve still had excellent results since losing closer Paul Sewald, pitching to a 1.89 ERA since the trade deadline. Moreover, they have essentially been using a seven-man bullpen as it is. Andrés Muñoz, Matt Brash, Trent Thornton, Tayler Saucedo, Justin Topa, Isaiah Campbell, and Gabe Speier have combined to pitch 45 2/3 of the 47 2/3 innings the Mariners bullpen has thrown since August 1. The Mariners will be counting on those seven to handle a difficult workload for the next while, but eventually, they should get some relief if Woo and Hancock do, in fact, move into a piggyback arrangement.

Gonzales and Ray are expected to rejoin the club at some point in 2024, at which point the Mariners will have an embarrassment of riches in the starting rotation. Gonzales is under team control through 2025, while Ray is signed through 2026. Castillo, meanwhile, is signed through 2027 with a vesting option for 2028. Gilbert is also under team control through 2027, Kirby through 2028, and the rookies through at least 2029 (pending further optional assignments).

With so many capable starters (and so many arms that will need a 40-man spot over the winter), there’s a good chance Dipoto will look to make a trade. The Mariners were reportedly willing to consider dealing one of their starting pitchers this summer, and they’ll have a better opportunity to do so over the offseason. The Cardinals, who have a surplus of young hitters but not nearly enough pitching, could be an interesting trade partner. They will be looking to add multiple starters this winter, and they were already linked to Gilbert earlier this year.

Mariners Outright Zach Muckenhirn

By | at

August 11: The Mariners announced today that Muckenhirn cleared waivers and has been outrighted to Triple-A Tacoma.

August 9: The Mariners have officially selected the contract of prospect Emerson Hancock, a move that was reported yesterday. In corresponding transactions, the M’s optioned right-hander Devin Sweet to Triple-A and designated left-hander Zach Muckenhirn for assignment.

Muckenhirn, 28, made his major league debut with the Mets earlier this year, tossing six innings over three appearances with four earned runs allowed. He was designated for assignment in July and then promptly traded to the Mariners as part of the deal that sent Trevor Gott and Chris Flexen to Queens. Flexen was released by the Mets shortly thereafter, highlighting the fact that they were taking on Flexen’s contract in order to effectively buy Gott.

The M’s saved some money in that deal but also added Muckenhirn to their system, sending him to Triple-A Tacoma. He’s thrown 8 2/3 innings for that club with a 9.35 ERA in that small sample, which likely helped loosen his grip on a roster spot. But he had a much more palatable 0.88 ERA in 30 2/3 innings for the Syracuse Mets prior to the trade, giving him a combined 2.75 ERA at Triple-A this year. He’s only struck out 14.8% of opponents at that level but has kept the ball on the ground on close to half of the balls in play he’s allowed.

With the trade deadline now in the rear-view mirror, the M’s will have a week to put Muckenhirn on outright waivers or release waivers. Left-handed relief tends to always be in demand and Muckenhirn can serve as a long-term depth option since he has just a few days of service time and a full slate of options. His strikeouts haven’t been there this year but he punched out 23.8% of minor league hitters last season, in addition to consistently solid ground ball rates.

If the lefty were to pass through waivers unclaimed, he would stick with the M’s since he lacks the necessary service time or previous career outright that’s necessary for the right to elect free agency. But if he’s still not on the roster at season’s end, he would qualify for minor league free agency.
