Mets Select Daniel Duarte
The Mets announced that they have selected the contract of right-hander Daniel Duarte. In a corresponding active roster move, fellow righty Joey Gerber has been optioned to Triple-A. To open a 40-man spot, lefty A.J. Minter has been transferred to the 60-day injured list.
Duarte, 29, signed a minor league deal with the Mets in the offseason. He has been with Triple-A Syracuse and putting up good numbers, at least on the surface. He has thrown 17 1/3 innings over 12 appearances, allowing 2.60 earned runs per nine.
Beneath the hood, things aren’t quite as impressive. His 19.7% strikeout rate and 12.7% walk rate are both subpar numbers. His 45.8% ground ball rate is above average but only by a few ticks. His ERA would be far higher without good luck, since his .255 batting average on balls in play and 82.5% strand rate are both to the fortunate side. His 4.21 FIP is perhaps a better representation of how he has pitched this year.
It’s possible Duarte is up to give the Mets some emergency length out of the bullpen. Their rotation is in a transitional phase at the moment, thanks to the recent injury to Clay Holmes. That leaves them with a four-man rotation consisting of Christian Scott, Nolan McLean, David Peterson and Freddy Peralta, with Peterson often pitching behind an opener. They have Tobias Myers and Sean Manaea as potential options for some bulk work, though Manaea tossed four innings behind Peralta yesterday and won’t be available for a few days.
Scott is starting tonight’s game. He hasn’t gone more than five innings in any game yet this year. McLean is listed as the starter for tomorrow’s game. It would be Holmes’s turn on Wednesday, so the Mets will need to figure out a plan for that game, whether it’s leaning on Myers as part of a bullpen game or calling someone up from the minors.
Five of Duarte’s 12 appearances this year have been two innings or longer, including three of the past four. He hasn’t pitched since May 12th, so he should be fresh and could help out in the coming days, perhaps if Scott can’t go very long tonight. Gerber hasn’t pitched since a game for Syracuse on the 12th but has mostly been throwing one-inning outings in the minors this year. Duarte still has an option and could be easily sent back down to Syracuse if he soaks up some frames and another fresh arm is needed.

Guardians’ Kolby Allard Granted His Release
The Guardians granted left-hander Kolby Allard his release yesterday, per Tim Stebbins of MLB.com. Allard had an opt-out clause in his contract, and Cleveland apparently didn’t have a spot for him on the big league roster. He’ll be free to explore opportunities with other teams, though Stebbins adds that the Guardians would prefer to re-sign Allard on a new minor league pact if possible.
Allard, 28, has been hit hard in a small sample of 8 2/3 innings with Cleveland this season. He’s served up 10 runs on 16 hits and three walks in that time, fanning nine of his 45 opponents (20%). He’s also allowed more runs than innings pitched in an even smaller sample of 5 1/3 Triple-A frames.
Though his 2026 season hasn’t gone as planned, Allard was terrific with Cleveland as recently as last season. In 2025, he ate up 65 innings in a swingman role and notched a tidy 2.63 earned run average. Allard’s 15.3% strikeout rate was about seven percentage points shy of league average, but his 5.3% walk rate was excellent (more than three points lower than average).
A former first-round pick, Allard was dogged by repeated back injuries early in his career with Atlanta. He never wound up establishing himself as the steady No. 4 starter many believed him capable of becoming, but he’s consistently found big league work as a journeyman bouncing from team to team in the same type of swing role in which he thrived last season. Allard has never thrown particularly hard, though this year’s 89.4 mph average four-seamer is down about a half mile from last year’s 89.9 mph and well shy of its 92.4 mph peak back in 2019.
Any team in need of some length in the bullpen or perhaps a handful of spot starts in the near future could plausibly consider Allard as an option. He’d have a stronger case for a big league spot with better 2026 performance, but Allard was great last year, solid this spring (4.05 ERA in 13 1/3 innings) and isn’t going to cost a new club much more than the league minimum for any time spent on the big league roster.
If Allard does end up back in Cleveland, they’ll be glad to keep the depth. The Guards have managed to make it to this point in the season only needing five starters: Parker Messick, Gavin Williams, Tanner Bibee, Joey Cantillo and Slade Cecconi. However, Cecconi has struggled to a 5.60 ERA, and the depth options in Triple-A are somewhat lacking.
Logan Allen, Trent Denholm, Pedro Avila and Ryan Webb all have ERAs of 5.45 or higher with the Guardians’ top affiliate in Columbus — the latter pair closer to 9.00. A triceps injury has limited Austin Peterson to four starts, though he recently returned from the injured list. Yorman Gómez has yet to pitch this season due to a shoulder injury. Former top prospect Daniel Espino is working exclusively in short relief after a yearslong injury absence. Twenty-six-year-old Rorik Maltrud (2.50 ERA in 39 1/3 frames) is the only starter in Columbus who’s taken the mound at least five times and kept his ERA under 5.00.
Red Sox Notes: Mayer, Narváez, Bello
Red Sox infielder Marcelo Mayer is lobbying for some shortstop time, per Tim Healey of The Boston Globe. Whether or not he gets the chance seemingly depends on how much time Trevor Story is going to miss.
Story has been battling a sports hernia this year and landed on the injured list in recent days. If he undergoes surgery, he’ll miss two months or so, though it’s still not a guarantee that he will go under the knife.
Mayer came up as a shortstop in the minors and also dabbled at second and third base. He has only played the keystone this year and hasn’t even been working out at short, though in the wake of Story’s injury, he plans to start practicing there. He has told manager Chad Tracy that he would like to help the team by moving across the bag. The skipper seems open to it if Story is going to be out a while, though he leans toward keeping Mayer at second if Story is slated for a quicker return.
It’s an understandable position for Tracy. Mayer only played 84 innings at second base in the minors and is still getting accustomed to the position. He is also still young at 23 years old and hasn’t fully clicked as a major league hitter yet, sporting a career line of .223/.278/.359. Mayer was once one of the club’s top prospects and the Sox presumably still hope for him to be a big part of the future, as he is under control for five more seasons after this one. There’s some logic in keeping him with his current plan and not adding a new assignment to his to-do list for just a brief interlude.
Since Story has been sidelined, the Sox have primarily been using Andruw Monasterio at short. Isiah Kiner-Falefa and Nick Sogard could also chip in at the position if Mayer is going to be staying at the keystone.
There’s also a situation to watch behind the plate, as Healey notes Carlos Narváez is dealing with an injury to the middle finger on his right hand. Though Narváez says the finger went “a little sideways,” X-rays were negative and he may avoid the injured list. The injury first popped up after a slide and then was aggravated when Narváez hit a ball off the end of his bat.
Most clubs have two catchers on the roster, so it would be a bit risky to proceed with one of them unavailable due to a day-to-day injury. However, the Sox currently have three backstops on the roster, with Mickey Gasper and Connor Wong also present. Gasper has been getting some at-bats as the designated hitter lately and perhaps that would become less likely if Narváez is unavailable. If Boston wants Gasper’s bat in the lineup, they could put him behind the plate while Narváez is hurt, perhaps opening more DH time for Masataka Yoshida.
Turning to the rotation, Chris Cotillo of MassLive suggests that Brayan Bello may get squeezed out of the rotation soon. The righty is having an awful season, with a 7.16 earned run average through 44 innings. The Sox used an opener in front of him for his first two appearances in May, which went well. He only allowed one run in each, going seven innings in the first outing and then 6 1/3 the second time. He got used as a traditional starter again yesterday but allowed seven earned runs in five innings.
Cotillo notes that Garrett Crochet is expected to come off the injured list around the end of this month, which could lead to Bello losing his spot since his rotation mates are faring much better than him. Sonny Gray, Ranger Suárez, Connelly Early and Payton Tolle all have ERAs of 3.21 or lower this year.
Though he signed a multi-year extension with the Sox, Bello does have options and could be sent to the minors if the Sox decide that’s what’s best for him and the team. Pitching from the bullpen could be another possibility, though the club may want to think about the long term. Bello is signed through 2029 with a club option for 2030. Assuming the hope is that he will still be a part of the rotation for years to come, keeping him stretched out may be preferable. On the other hand, he hasn’t been optioned to the minors since April of 2023 and clubs are sometimes reluctant to send guys down after they have seemingly become established as big leaguers.

KBO’s Kiwoom Heroes Sign Keston Hiura
The Kiwoom Heroes of the Korea Baseball Organization announced this week that they’ve signed former big league infielder Keston Hiura for the remainder of the 2026 season (link via Jee-ho Yoo of South Korea’s Yonhap News Agency). They’ve waived another former big leaguer, outfielder Trenton Brooks, in a corresponding move. Hiura drew interest from Japan’s Nippon Professional Baseball as well before signing with the Heroes. The GSI client will be guaranteed $400K for the rest of the 2026 season and has another $100K available to him via incentives.
Hiura, 29, was the ninth overall pick by the Brewers back in 2017. He ranked as a top prospect for years and has a huge track record in the upper minors but has struggled with high strikeout rates in the majors. He still sports a .235/.314/.442 line in the majors (101 wRC+), but the vast majority of that production came in a standout rookie showing back in 2019, when he hit .303/.368/.570 with 19 homers (and a 30.7% strikeout rate) in 348 plate appearances. In parts of five seasons since, Hiura has batted .203/.289/.381 while striking out at a 38.3% clip.
Big league struggles notwithstanding, Hiura has repeatedly shown himself to be a force against Triple-A pitching. He’s played parts of six seasons at the top minor league level and laid waste to Triple-A pitching, slashing .291/.392/.563 with 103 round-trippers, 77 doubles and five triples in 1684 plate appearances (392 games). Strikeouts have still been an issue, but not to the same level as in the majors. He’s fanned in 27.8% of his Triple-A plate appearances and drawn walks at a 10.3% clip. Hiura was drafted as a second baseman but has played more first base and left field in recent years.
Brooks, 30, appeared briefly in each of the past two major league seasons, totaling 72 plate appearances between the Padres and Giants. He hit .136/.208/.212 in that tiny sample but is a .279/.382/.472 hitter in his career at Triple-A. He struggled to find his footing in South Korea, going 31-for-143 (.217) without a homer. He’ll wrap up his Heroes tenure with a .217/.286/.259 slash.
Pirates Expected To Promote Jhostynxon García
9:52am: While García is expected to be promoted, Hiles adds in a follow-up report, the Pirates have been considering one other player as well. A decision has not yet been finalized.
8:55am: The Pirates are set to recall outfielder Jhostynxon García from Triple-A Indianapolis, reports Noah Hiles of the Pittsburgh Post-Gazette. The Bucs are off today, so the move won’t be official until tomorrow’s road date with the division-rival Cardinals in St. Louis. The Pirates already optioned infielder/outfielder Nick Yorke to Indianapolis following yesterday’s game.
García, 23, was acquired from the Red Sox in the offseason trade sending Johan Oviedo to Boston. “The Password” ranked on various top-100 prospect list during the 2025 season but has slipped a bit; he’s still a generally well-regarded outfield prospect who’s bounced back from an awful start to his 2026 season to catch fire.
Despite an eye-popping spring with the Pirates in which he batted .405/.463/.595 in 41 plate appearances, García opened the season in the minors. The Pirates had Oneil Cruz, Bryan Reynolds and Ryan O’Hearn locked into outfield spots and Marcell Ozuna at designated hitter. The Bucs understandably wanted García getting everyday reps rather than sparse playing time on the bench when he’s still in his formative, developmental years. The situation is a bit different now, with O’Hearn hitting the injured list over the weekend and Ozuna having struggled through an awful 39-game stretch to begin his season (.182/.271/.311).
García himself opened the season mired in a 1-for-27 slump through his first 29 trips to the batter’s box. He broke out with a three-hit game on April 5 and hit safely in six of seven games before landing on the minor league injured list due to a back injury. García rehabbed with the Pirates’ Class-A club for a few days in early May, then erupted with a 5-for-5, three-homer outburst in his return to the Triple-A lineup last month. Overall, since that three-hit game in early April, he’s slashed .324/.365/.632. It’s only 68 total plate appearances — a handful of them in A-ball — but it’s clear that García has broken out of that early-season slump.
For the Pirates, the inverse is true. Pittsburgh was swept by their intrastate rivals over the weekend, dropping three straight to Philadelphia by scores of 11-9, 6-0 and 6-0. The Pirates were 16-11 back on April 25 and have gone 8-12 since. They’re still a game over .500, at 24-23, but they’ve five games back of the Cubs for the NL Central lead and 3.5 games out in the NL Wild Card hunt.
García should jump into the mix and get everyday at-bats, likely in right field in place of O’Hearn. Jake Mangum can float between all three outfield spots as needed. If García is hitting well when O’Hearn is ready to return from the injured list, that could put some pressure on Ozuna — at least as long as the rest of the roster is healthy. Reynolds, Cruz and O’Hearn have been key cogs in a Pirates lineup that ranks sixth in the majors in runs scored (229), sixth in batting average (.248), fourth in on-base percentage (.332) and is tied for 13th in slugging percentage (.388). They’re not going to be displaced. O’Hearn can also play first base, but Spencer Horwitz is slashing .273/.383/.414, so he’s not going anywhere either.
García made his major league debut with the Red Sox last year, but he received only nine plate appearances and accrued just nine days of major league service time. There isn’t enough time left on the calendar for him to reach a full year of service in 2026, so he’ll be controllable all the way through 2032 in Pittsburgh. Future optional assignments could change that trajectory, of course. He’s in his second minor league option year and will have one remaining beyond the current season.
The Opener: White Sox, NL West, Pearson
Mariners top prospect Colt Emerson debuted on Sunday night against the Padres. A recurrence of Brendan Donovan‘s groin injury opened up a job for the 20-year-old. He’s expected to have a clear path to everyday playing time moving forward. “This period will give him some runway,” GM Justin Hollander said (h/t Daniel Kramer of MLB.com). “This is not a 15-at-bat or a 20-at-bat tryout to see if he’s capable of taking the job and running it with it for the rest of the year.”
1. White Sox take Crosstown Classic series
With a wild walk-off win on Sunday, the White Sox took two of three games against the Cubs over the weekend. Tristan Peters broke a 4-4 tie in the bottom of the eighth inning with a three-run blast, his first career home run. Michael Conforto matched it with a three-run homer in the top of the ninth inning. After holding the Cubs to a run in the 10th inning, Edgar Quero went deep to win it. The most recent victory pushed the club two games over .500 for the first time since 2022 (h/t Bob Nightengale of USA Today). The White Sox are suddenly two games out of first place in the AL Central.
2. NL West showdown in San Diego
The Padres cruised past Emerson’s Mariners last night, sweeping the Vedder Series and moving within a half game of the division-leading Dodgers. The in-state rivals will begin a three-game set on Monday night. Los Angeles recently shook off a four-game losing streak, recovering to secure a split in a series against the Giants before sweeping the Angels over the weekend. The aces will be on the mound for both squads, with Yoshinobu Yamamoto facing off against Michael King.
3. Pearson nearing Astros debut
The Astros inked Nate Pearson to a big-league deal this offseason with the intention of stretching him out as a rotation option. The former Blue Jays top prospect went down with elbow soreness in the spring and opened the year on the injured list. Houston has now nixed the plan to make Pearson a starter. The hard-throwing righty has worked in short stints during his rehab at Triple-A. Pearson is expected to join the team for a series in Minnesota beginning on Monday, per Brian McTaggart of MLB.com. He’ll look to boost a bullpen that ranks dead last in ERA.

Mariners Promote Colt Emerson, Place Brendan Donovan On IL
The Mariners are adding top prospect Colt Emerson to the big-league squad, first reported by Ryan Divish of the Seattle Times. The 20-year-old shortstop is among the highest-ranked young players in the sport. The team has officially announced the promotion. Brendan Donovan was placed on the 10-day IL with a groin strain as the corresponding move.
The Mariners released an updated lineup for Sunday Night Baseball against the Padres. Emerson is now batting ninth and playing third base instead of Leo Rivas. He’ll be the youngest Mariner to make his debut since 19-year-old Félix Hernández in 2005, according to the team.
Emerson fell short of an MLB gig out of Spring Training, despite a 111 wRC+ in 18 games. The 20-year-old has slashed .255/.347/.469 through 38 games at Triple-A this season. He’s popped seven home runs to go with 10 stolen bases.
Seattle inked Emerson to an eight-year, $95MM extension in late March. The price tag is a record figure for a player who has yet to appear in the majors. MLB Pipeline has Emerson ranked sixth among all prospects. FanGraphs has the infielder just outside the top 10.
The Mariners didn’t give Emerson an opportunity in the majors when shortstop J.P. Crawford was working through a shoulder injury early in the year. It would seem another injury to an infielder has opened the door for the youngster. Donovan had been out of the lineup since Friday. He’s been the club’s everyday third baseman when healthy. Emerson has played mostly shortstop with Tacoma, but he’s made five starts at the hot corner this season.
Donovan has dealt with groin issues since the offseason. He underwent sports hernia surgery before the 2026 campaign got underway. The infielder hit the IL in late April with a groin strain. After just seven games, Donovan is back on the injured list with the same injury. With Emerson taking over at third base, the versatile Donovan will move around to multiple spots when healthy, per Adam Jude of the Seattle Times. There’s no timetable for his return, but the club hopes he can get back to full strength in a few weeks, per Divish.
Seattle took Emerson with the 22nd overall pick in the 2023 draft. He moved quickly through the lower levels of the minors. Emerson posted an impressive 129 wRC+ across three levels last year, capped off by a massive .364/.444/.727 line in a brief sample at Triple-A. He hasn’t been as dominant so far this season, particularly in terms of contact. Emerson has a career-high 27.2% strikeout rate over 169 plate appearances in the minors this year. The power and speed have been among the best he’s shown, though. Emerson’s 16 homers and 14 steals in 2025 were both career highs. He would’ve blown past those marks if he had stayed with Tacoma much longer.
