Rockies Select Carson Palmquist
The Rockies announced that they have selected left-hander Carson Palmquist to their roster. Thomas Harding of MLB.com reported yesterday that Palmquist was likely to be promoted and to make his major league debut starting tonight’s game. They also reinstated infielders Ezequiel Tovar, Tyler Freeman and Aaron Schunk from the 10-day injured list. To make room for those four, outfielder Sean Bouchard and right-hander Anthony Molina have been optioned to Triple-A Albuquerque while infielders Owen Miller and Alan Trejo have been designated for assignment.
Palmquist, now 24, was selected by the Rockies in the third round of the 2022 draft. Since then, he has been climbing the minor league ladder, putting up some good strikeout numbers but also giving out a fairly high number of free passes.
Overall, he has 246 1/3 minor league innings under his belt with a 3.91 earned run average. He has punched out 31.1% of opponents but also given out a walk 117 times, an 11.2% clip. He has also plunked 21 batters, only adding to the number of free bases he’s given out.
That includes 70 2/3 Triple-A innings, starting in August of last year and continuing through the present. For the Isotopes, who play in the hitter-friendly Pacific Coast League, Palmquist has a 4.84 ERA, 24.1% strikeout rate and 14.3% walk rate.
Coming into 2025, Baseball America ranked Palmquist as the #8 prospect in the Rockies’ system. They note that the sidearming lefty doesn’t have overpowering stuff, with his fastball generally sitting in the low-90s, but with his angle and extension helping him get results from it. He’s been able to generate a lot of whiffs with his slider while also mixing in a cutter and a changeup. FanGraphs ranked him #6 in the system with a fairly similar report.
Both outlets feel Palmquist has a shot to be a serviceable back-end starter. There’s not much stopping the Rockies from letting him begin that journey now. The team has a dreadful 7-36 record, easily the worst in the majors. Since Ryan Feltner landed on the injured list a couple of weeks ago, they have had a four-man rotation core of Germán Márquez, Kyle Freeland, Antonio Senzatela and Chase Dollander, while also giving spot starts to Bradley Blalock and Tanner Gordon.
Both Blalock and Gordon are currently on optional assignment in the minors. Each of Márquez, Freeland, Senzatela and Dollander has an ERA above 6.00. The Rockies are about to play 13 straight games, starting tonight. Perhaps this will just be a spot start for Palmquist, though he could also get three turns if he stays up for the rest of this 13-game stretch.
Even if Palmquist doesn’t get an extended rotation look right away, there’s a long-term path. Márquez is an impending free agent, as is Austin Gomber, who is currently on the IL. Senzatela and Freeland are both only signed through 2026. Senzatela’s pact has a $14MM club option for 2027 though it’s hard to see that being picked up right now. Freeland can unlock a $17MM player option for 2027 by pitching 170 innings in 2026, though he has only hit that number twice in his career. Even if he’s trending towards hitting it next season, the Rockies would probably be wise to reduce his workload and not allow him to, unless he is having far better results between now and then. In that scenario, he might turn down his option and head to free agency.
Regardless of how those options play out, there should be room for young guys like Dollander, Palmquist and Blalock to take over rotation jobs in the long run, though the difficulties of pitching at Coors Field make that a tricky task even for the most talented pitching prospects.
On the position player side, Tovar, Freeman and Schunk are all back in the infield mix. That squeezes out Trejo and Miller, each of whom are out of minor league options. Trejo returned to the organization last month in a trade with Texas. He hit .175 in 14 games. Miller, acquired in a minor league deal with Milwaukee over the offseason, was promoted around the same time. He went 2-14 over nine contests. Both players figure to land on waivers in the next few days.
Brewers Acquire Rob Zastryzny From Yankees
Left-hander Rob Zastryzny has been traded from the Yankees to the Brewers, according to announcements from both clubs. Andrew Wagner of Freeman Sports was among those to notice earlier that Zastryzny was in the Brewer clubhouse. The Yanks, who signed the southpaw to a minor league deal, receive cash considerations in return. The Brewers have selected the lefty to their roster and optioned righty Elvis Peguero as the corresponding move. Milwaukee already had an open 40-man spot via Vinny Capra being designated for assignment recently.
As mentioned, Zastryzny signed a minor league deal with the Yankees in the winter. He has been at the Triple-A level so far this year with mediocre surface-level results but better numbers under the hood. Through 12 innings, he has a 23.5% strikeout rate, 50% ground ball rate and no walks. Though he has a 4.50 earned run average, thanks to a .378 batting average on balls in play and 60.6% strand rate.
The Brewers are already familiar with Zastryzny, as he pitched for them last year. He signed a minor league deal with Milwaukee ahead of the 2024 campaign and was called up in the summer. However, he only got to make nine appearances before some left elbow tendinitis put him on the injured list in late July. He stayed on the IL through the end of the year and was put on waivers in November, with the Cubs claiming him. He later cleared waivers in February and elected free agency, which led to his deal with the Yankees.
Zastryzny has pitched in six separate MLB seasons but has just 67 innings under his belt. In that time, he has a 4.30 ERA, 18.2% strikeout rate, 10.5% walk rate and 44.8% ground ball rate. His minor league numbers have generally been better. From 2021 to the present, he has thrown 143 2/3 innings on the farm with a 3.57 ERA, 29.1% strikeout rate and 7.6% walk rate.
He finished last year hurt but appears to be healthy now. Perhaps he had some sort of opt-out or upward mobility clause in his contract, with the Brewers more willing to give him a roster spot than the Yankees.

Phillies Place Aaron Nola On IL With Ankle Sprain
The Phillies announced that they have placed right-hander Aaron Nola on the 15-day injured list, retroactive to May 15th, due to a sprained right ankle. Right-hander Daniel Robert has been recalled to take his roster spot. Todd Zolecki of MLB.com was among those to report that prospect Mick Abel will be promoted to make his major league debut but only to make a spot start on Sunday. After that, he will be optioned to Triple-A and Taijuan Walker will take Nola’s rotation spot. In other Philly news, manager Rob Thomson relayed that prospect Moisés Chace will undergo Tommy John surgery. Lochlahn March of the Philadelphia Inquirer was among those to pass that along.
Per March, Nola injured his ankle prior to his recent start in Cleveland. He went on to allow four earned runs in five innings in that game. His next start was even worse, as Nola allowed nine earned runs over 3 2/3 innings against the Cardinals on Wednesday.
Perhaps the ankle injury provides an explanation for those outings but Nola was also struggling before that, with a 4.61 earned run average over his first seven starts this year. Though for what it’s worth, he was building a bit of momentum. On April 27th, he pitched seven innings of one-run ball against the Cubs, then six scoreless against the Diamondbacks on May 3rd.
Whether it’s due to the ankle or not, Nola now has a 6.16 ERA on the year. His 23.6% strikeout rate, 7.3% walk rate and 44.6% ground ball rate are all decent numbers, but 11 home runs have pushed more runs across the plate. SIERA, which expects home run rate to normalize, has Nola at 3.66 this year. However, home runs have always been a part of Nola’s game, so that might not be the best metric in this specific instance. The Phillies haven’t provided an estimate for how long they expect Nola to be out but it seems he will miss at least a few turns.
Nola’s injury will allow Walker to return to the rotation. He started his season with six great starts, posting a 2.54 ERA in those. But when Ranger Suárez was ready to come off the IL, someone had to go. Walker got bumped to the bullpen as the Phils ran with a rotation of Suárez, Nola, Zack Wheeler, Jesús Luzardo and Cristopher Sánchez. Walker made two relief appearances, each three innings long. The first was scoreless but he allowed three earned runs in the second one, which came in relief of Nola on Wednesday.
He’ll retake a rotation spot next week, but Abel will get to make his major league debut in the interim. A former first-round pick, Abel’s prospect stock has dropped a bit due to some inconsistent control. From 2021 to 2024, he tossed 375 minor league innings and struck out 26.9% of batters faced but he also gave out walks at a 13.3% clip, leading to a 4.75 ERA.
Despite the rough edges, the Phils added him to their 40-man roster in November, to keep him out of the Rule 5 draft. The early results are encouraging this year. He has a 2.53 ERA through eight Triple-A starts, with a 26.6% strikeout rate and 49.2% ground ball rate. His 9.9% walk rate is still a bit higher than par but an improvement for him. He’ll get a chance to make a brief debut this weekend.
As for Chace, it’s obviously an unfortunate blow for him. Acquired from the Orioles in last summer’s Gregory Soto trade, Chace is one of the club’s top pitching prospects and a fringe top 100 guy. He wasn’t on every list but FanGraphs had him at #74 coming into the year, ESPN at #90 and Baseball Prospectus put him in their #101 slot.
Like Abel, Chace was given a 40-man spot in November to keep him out of the Rule 5 draft. He started this year at Double-A and could have worked his way to Triple-A or even the majors during the 2025 season. That will now be on pause for a long time, as he should be rehabbing until the summer of 2026. The Phils could recall him and place him on the major league 60-day injured list at some point if they so choose. Doing so would open a 40-man spot but would also require Chace to start earning big league pay and service time.

Yankees Designate Tyler Matzek For Assignment
The Yankees announced that left-hander Tyler Matzek has been designated for assignment. That opens an active roster spot for right-hander Jonathan Loáisiga, who has been reinstated from the 15-day injured list. Their 40-man roster count drops from 39 to 38.
Matzek, 34, was selected to the big league roster a bit less than a month ago. He has since tossed 6 1/3 innings for the Yankees over seven appearances. He allowed three earned runs in that time, leading to a passable 4.26 ERA. However, he issued five walks in that span, a 14.3% rate.
That’s a fairly small sample but control has been a problem for Matzek in the past. He has an 11.7% walk rate in his big league career. His early-career stint with the Rockies was hampered by those control issues. He later revitalized his career in Atlanta but still worked around some fairly high walk totals. From 2020 to 2022, he posted a 2.92 with Atlanta despite walking 13.4% of batters faced. However, he also struck out 27.4% of opponents.
He wasn’t able to pitch much in the past two seasons. He required Tommy John surgery late in 2022, wiping out his 2023. Last year, further elbow troubles kept him on the shelf for much of it. He only got to pitch 10 innings in the big leagues.
The Yanks were able to get him on a minor league deal this winter and brought him up to the majors, but they appear to be quickly moving on. This will leave them a bit short on left-handed relief. Ryan Yarbrough has been working bulk innings, so Tim Hill as the only true southpaw reliever now that Matzek is gone.
DFA limbo can last as long as a week, though the waiver process takes 48 hours, meaning any trade possibilities would have to be explored in the next five days. Matzek’s recent track record isn’t much to go on but he at least has some past success. If he passes through waivers unclaimed, he has more than enough service time to reject an outright assignment and elect free agency.
As for Loáisiga, he’ll be looking to make a comeback from a lengthy injury absence. He had a really strong season in 2021, pitching 70 2/3 innings for the Yankees with a 2.17 ERA, 24.4% strikeout rate, 5.7% walk rate and 60.9% ground ball rate. But in 2022, he battled some shoulder troubles and posted a 4.13 ERA. In 2023, he was limited to just 17 appearances by elbow issues and eventually underwent UCL surgery early in 2024.
Though he was going to start the 2025 season on the injured list, the Yankees believed in him enough to bring him back. They signed him to a major league deal with a $5MM guarantee and a club option for next year. He’ll be a bargain if he can get back to that 2021 form. The early results have been good, as he threw seven innings on his rehab assignment with nine strikeouts and no walks, allowing just one earned run.

Red Sox Select Nick Burdi
The Red Sox announced that they have selected the contract of right-hander Nick Burdi. Fellow righty Cooper Criswell has been optioned as the corresponding active roster move. To open a 40-man spot, righty Kutter Crawford has been transferred to the 60-day injured list.
Burdi, 32, signed a minor league deal with the Sox in the offseason. He has since been putting up some good numbers for Triple-A Worcester. Through 16 2/3 innings, he has only allowed one earned run, leading to a 0.54 ERA. He has struck out 38.5% of opponents while only giving out walks 7.7% of the time.
Throughout his career, the question has been more about health than talent. A former second-round pick of the Twins, he has twice had Tommy John surgery, once in 2017 and the second time in 2020. He also had a thoracic outlet syndrome surgery in between those two, in 2018.
He understandably didn’t pitch much from 2016 to 2022 but has been able to log some innings more recently. In 2023, he only pitched three big league frames but also got to 21 innings on the farm, with a 3.86 ERA and 35% strikeout rate. He also walked 15% of opponents that year, perhaps understandably rusty after so much missed time.
Last year, he pitched 9 2/3 major league innings for the Yankees with a 1.86 ERA as well as 17 Triple-A innings with a 2.65 ERA. At both levels, he had high strikeout totals but also a lot of walks. He missed time with a hip injury and was outrighted off the roster late in the season, which allowed the Red Sox to sign him.
It’s a small sample but Burdi’s start this year still features the same strikeout stuff but seemingly with better control. He’s averaging 96 miles per hour on his fastball while also throwing a slider and changeup. The Sox will add him as a fresh arm, at least for a few days. They only have a four-man rotation right now with Walker Buehler expected to be reinstated from the IL in the coming days, perhaps on Tuesday. Burdi has options, so it’s possible he’ll be sent down when Buehler is ready, depending on how things go between now and then. If he manages to stay healthy and post some big numbers in the majors, he can be retained beyond this season via arbitration if still on the 40-man roster.
As for Crawford, this doesn’t change anything with him. The 60-day count is retroactive to his initial placement on the 15-day IL. He landed there to start the campaign due to right patellar tendinopathy. He will be eligible for reinstatement in late May, but that doesn’t seem likely anyhow. He has been throwing lately but hasn’t yet begun a rehab assignment. Even if cleared to start that assignment soon, he would surely need a few weeks to ramp up as a sort of delayed spring training.

Cubs Sign Kenta Maeda To Minor League Deal
The Cubs are signing veteran righty Kenta Maeda to a minor league contract, as first reported by Japanese news outlet Daily Sports. Cubs skipper Craig Counsell confirmed the signing to the team’s beat today (link via Vinnie Duber for the Chicago Sun-Times). Maeda, a Boras Corporation client, was released by the Tigers last week.
“He has had success,” Counsell said of Maeda today. “He’s struggled. … It’s a player you’ve got to have constant conversations with and see where we can make some adjustments and see where he’s at.”
Maeda, 37, has a lengthy big league track record of success. He signed with the Dodgers via the MLB/NPB posting system ahead of the 2016 season and spent the next four years with Los Angeles, pitching to a sharp 3.87 ERA in 589 innings between the Dodgers’ rotation and bullpen.
In the 2019-20 offseason, the Twins sent righty Brusdar Graterol and outfielder Luke Raley to the Dodgers in exchange for Maeda and catching prospect Jair Camargo. Maeda was sensational for Minnesota in the pandemic-shortened 2020 season, firing 66 2/3 innings of 2.70 ERA ball with a 32.3% strikeout rate and 4.3% walk rate. His got out to a sluggish start in 2021, however, and wound up requiring Tommy John surgery. That procedure knocked out his entire 2022 campaign.
Maeda returned to the Twins for the 2023 season — the final year of his original eight-year pact with the Dodgers. It was an uneven year, with Maeda stumbling early and hitting the injured list again after serving up 10 runs to the Yankees in late April. He returned a triceps injury in June and looked very much like the 2020 version of himself; in his final 88 2/3 innings that year, Maeda pitched to a 3.36 ERA with a 29% strikeout rate and 7% walk rate.
Entering the 2023-24 offseason, Maeda appeared a strong candidate for a multi-year deal. The Tigers signed him to a two-year, $24MM contract that seemed eminently reasonable given his strong finish to the ’23 season and his broader track record of success. Instead, it proved to be a misstep.
Maeda ate 112 1/3 innings for the Tigers in 2024 but struggled considerably as a starter. Detroit moved him to the bullpen in early July, and Maeda quietly turned his season around, at least to an extent. He made a dozen appearances as a long reliever over the next couple months, pitching to a 3.86 ERA with a 23.8% strikeout rate and 4.1% walk rate in 42 innings.
It was a nice run of quality contributions from a right-hander who is plenty familiar with that sort of long relief/swingman role. The Tigers gave him one final start in late September, and Maeda was tagged for five runs in 4 2/3 innings. Overall, Maeda finished the 2024 season with a grisly 6.09 earned run average.
Spring training 2025 brought reason for some cautious optimism. Maeda’s 4.91 ERA in 14 2/3 innings wasn’t much to look at, but he posted a gargantuan 39.7% strikeout rate against a microscopic 1.7% walk rate. That, coupled with some health troubles elsewhere in the rotation, earned Maeda another chance to carve out a role on Detroit’s staff.
It didn’t go well.
Maeda was deployed as a multi-inning reliever and yielded runs in four of his seven appearances. By the time the Tigers designated him for assignment, he was sitting on a 7.88 ERA with a career-low 18.6% strikeout rate and a career-worst 14% walk rate. He’s never been a hard thrower, but this year’s 90.2 mph average fastball is a career-low.
The Cubs’ rotation at the moment is quite banged up. Justin Steele is out for the year after undergoing UCL surgery. Shota Imanaga is on the 15-day injured list due to a hamstring strain. Javier Assad opened the year on the IL with an oblique strain, began a rehab assignment late last month, and was pulled back after experiencing renewed discomfort. Subsequent imaging revealed a Grade 2 oblique strain. He’s on the 60-day IL and won’t return anytime soon. The Cubs’ rotation currently includes Jameson Taillon, Matthew Boyd, Colin Rea, Ben Brown and top prospect Cade Horton.
Maeda is hardly a guarantee to bolster the staff, whether as a starter or long reliever, but there’s little harm in the Cubs taking what amounts to a free look at the seasoned right-hander. The Tigers are on the hook for Maeda’s $10MM salary this year, minus the prorated portion of the $780K MLB minimum for any time he spends on another team’s big league roster. For now, it seems likely that Maeda will head to Triple-A and look to get back on track. He could be an option if Chicago needs a spot start or some length in the bullpen within the next few weeks.
White Sox Acquire Miguel Castro From Astros
May 16: The White Sox announced the trade. However, rather than the cash considerations indicated by Brown, the Sox announced that they’re sending international bonus pool space back to Houston in the swap. Pool space must be traded in $250K increments unless a team is emptying out a bonus pool that has under $250K remaining (in which case the entire remainder is sent).
Given the Sox’ position and long-term outlook, it seems likely that they’re sending at most $250K or perhaps that they had less than that amount remaining. Notably, no actual cash changes hands when pool space is traded. The Astros are simply acquiring the right to spend an additional block of cash on international amateur free agents.
May 15: The White Sox are acquiring right-hander Miguel Castro from the Astros, reports Robert Murray of FanSided. Astros general manager Dana Brown tells Chandler Rome of The Athletic that Houston receives cash considerations in return.
Castro, 30, signed a minor league deal with the Astros in the offseason. He has since pitched 19 2/3 innings at the Triple-A level with a 2.29 earned run average. His 10.1% walk rate is a tad high but he’s striking out 25.3% of opponents while getting grounders on 44% of balls in play.
Despite those solid numbers, it seems the Astros weren’t planning to call him up, so they’ve traded him instead. Per Ari Alexander of KPRC 2, Castro’s deal had an upcoming opt-out date on June 3rd.
The White Sox are rebuilding and don’t have a strong relief group. Collectively, their bullpen has a 4.42 ERA, putting them in the bottom third of major league teams. Given that they are 14-30 and at the bottom of the American League standings, they presumably plan to install Castro into the bullpen and see if he can pitch his way into being a midseason trade candidate. Assuming they plan to call him up before his opt-out, they will need to open a 40-man spot for him.
Castro has occasionally been a useful pitcher in the big leagues, though with declining results in recent seasons. His ground ball rate has been fairly consistently near 50% and his walk rate has usually been a bit higher than average. The strikeouts have been high at times but there’s been a clear downward trend. He peaked at 33% in 2020 but that figure dropped to 25.4% in 2021, 23.7% in 2022 and 22.4% in 2023.
Last year, he started with the Diamondbacks but landed on the injured list due to shoulder inflammation in the middle of April. He stayed there for about three months, getting reinstated in July but was released in early August. Around the IL stint, he tossed 13 2/3 innings with a 5.93 ERA and 12.5% strikeout rate in that small sample. Based on his minor league numbers this year, it’s possible he has put the shoulder problems behind him and is back in good form.

White Sox Release Brandon Drury
The White Sox released Brandon Drury from his minor league deal, according to the MiLB.com transaction tracker. He has been on the injured list since May 8.
Drury hasn’t played a game for Triple-A Charlotte since April 26. Their manager, Sergio Santos, told Jeff Cohen of Future Sox last week that Drury had injured his wrist on a hit-by-pitch. At the time, Santos said that Drury was able to field without issue but experienced soreness when he was taking swings. He’d only been able to appear in 10 games before the injury. The veteran infielder hit .179/.319/.282 with one home run across 47 trips to the plate.
The Sox signed Drury to a minor league contract shortly before the opening of Spring Training. He looked well on his way to breaking camp when he raked at a .410 clip through 13 exhibition contests. That was scuttled when he broke his left thumb in the final few days of Spring Training. Chicago granted him his release but brought him back on a new minor league deal in mid-April once he’d returned to health.
There aren’t many specifics on his latest injury, but it stands to reason that Drury will find renewed minor league interest whenever he’s healthy. He won a Silver Slugger in 2022 and remained an above-average hitter as recently as ’23, when he hit .262/.306/.497 with 30 doubles and 26 homers for the Angels. The wheels fell off last season. His bat cratered to a .169/.242/.228 showing across 360 plate appearances, limiting him to minor league offers.
Diamondbacks Trade Jose Castillo To Mets
The Mets acquired lefty reliever José Castillo from the Diamondbacks for cash, the teams announced. New York designated righty Kevin Herget for assignment to create a spot on the 40-man roster. Arizona had designated Castillo for assignment on Monday.
Castillo has technically appeared in five MLB seasons, though all but eight of his appearances came with the Padres during his 2018 rookie season. He turned in a 3.29 ERA over 38 1/3 innings that year but was subsequently set back by injury.
The 29-year-old signed a minor league deal with the Snakes in November. It marked his second consecutive season in the Arizona organization. He had spent all of last year with their Triple-A team in Reno, though he lost the first half of that season to injury. The Diamondbacks assigned him back to Reno to begin this season. He struck out seven while tossing 5 1/3 innings of one-run ball and was called up at the beginning of May.
The 6’6″ southpaw only spent a couple weeks in Torey Lovullo’s bullpen. He didn’t pitch well, allowing eight runs on 10 hits (including a trio of home runs) over 6 1/3 frames. Arizona bumped him out of the bullpen when Kendall Graveman returned from injury. Castillo is out of options, so they needed to designate him for assignment to take him off the MLB roster.
That out-of-options status means the Mets are prepared to give Castillo at least some time in their big league bullpen. They’ve been forced to scour the lefty relief market after losing Danny Young and A.J. Minter to season-ending injuries. They called up Génesis Cabrera from Triple-A Syracuse. He’s the only southpaw in Carlos Mendoza’s relief corps. Cabrera has managed five innings of one-run ball over four outings, but he had walked nearly 15% of opposing hitters in Triple-A before the promotion.
The Mets will need to remove someone from the major league bullpen once Castillo reports to the team. Dedniel Núñez is the obvious candidate, since he still has a couple options remaining. Cabrera is out of options, so the Mets would need to designate him for assignment if they wanted to use Castillo as their only left-hander.
Herget relinquishes his spot on the 40-man roster. The Mets claimed the 34-year-old off waivers from Milwaukee early last offseason. He only spent one day on the MLB roster, allowing two runs on three hits in one inning. He has otherwise been working out of the bullpen at Syracuse. Herget has only allowed five runs over 15 2/3 innings, but that came with a pedestrian 13:7 strikeout-to-walk ratio. He had a much stronger 32.4% strikeout rate over 38 appearances with Milwaukee’s top farm team a year ago.
The Mets will likely place Herget on waivers within the next few days. He has been outrighted twice in his career and would have the right to elect free agency if he goes unclaimed.
Rangers Release Adrian Houser
Righty Adrian Houser was granted his release from his minor league contract with the Rangers, the team announced. Jeff Wilson of DLLS Sports reports that Texas hopes to bring him back (presumably on a fresh minor league deal), but he’ll have the opportunity to explore other offers.
Houser signed with the Rangers during the offseason. He has worked out of the rotation at Triple-A Round Rock, tallying 39 1/3 innings across nine appearances. While his 5.03 earned run average is pedestrian, that’s not all that uncommon in the Pacific Coast League. Houser has stronger peripherals. He’s striking out a decent 22.8% of opponents while running an excellent 57.3% grounder rate.
Ground balls are Houser’s speciality. He has gotten grounders at a near-52% clip over parts of eight seasons in the majors. That was up in the 58-59% range during his best seasons with Milwaukee but has been down to a more normal 46-48% mark over the past few years. That caught up to him last year, as he allowed 5.84 earned runs per nine across 69 1/3 frames with the Mets. Houser had begun the season in New York’s rotation but was kicked to the bullpen after seven starts.
His results in relief were much better. Houser carried an ERA north of 8.00 as a starting pitcher but turned in a 3.28 mark across 35 2/3 relief innings. Texas seemingly preferred him as rotation depth, though it stands to reason he could find interest from other clubs as both a starter and reliever.
