White Sox Place Dominic Leone On 60-Day Injured List With Right UCL Sprain
The White Sox announced that they have reinstated right-hander Matt Foster from the 60-day injured list. In a corresponding move, fellow righty Dominic Leone was placed directly onto the 60-day IL with a sprain of his right ulnar collateral ligament. Daryl Van Schouwen of the Chicago Sun-Times relayed on X prior to the official announcement that Foster would be activated and Leone would be going on the IL.
Foster, now 29, had a decent showing with the Sox from 2020 to 2022. In that time, he made 108 appearances for the Sox, allowing 4.39 earned runs per nine innings. He struck out 23.7% of batters faced and gave out walks at an 8.2% clip.
Unfortunately, he required Tommy John surgery in April of 2023, turning that into a totally lost season for him. He has been on the injured list since then and began a rehab assignment in June of this year. He has thrown 14 2/3 innings on the farm this year as part of that rehab with a 2.45 ERA, 30.8% strikeout rate and 7.7% walk rate.
Foster qualified for arbitration for the first time after the 2023 campaign. Though he was still rehabbing from his surgery, the Sox tendered him a contract. But due to his missed time, he was only able to get a raise to $750K, barely above this year’s $740K league minimum salary.
He’ll likely be looking at yet another modest raise in arbitration this winter, since he’s already missed most of the season. The Sox can get a look at him over the next few weeks and decide what role they want him to play on next year’s club.
As for Leone, it’s unclear exactly how serious this injury is, but it’s evidently enough to end his season. By going directly onto the 60-day IL, he can’t come back during the regular season. The Sox are trending towards one of the worst seasons in history, currently sporting a record of 29-93, so the playoffs obviously aren’t remotely a consideration.
The veteran signed a minor league deal with the Sox and cracked the Opening Day roster, but he’s spent most of the season on the IL. Lower back tightness put him there for a couple of weeks in May. Just a few days after returning from that issue, he went back to the IL with right elbow inflammation. That elbow issue put him out of action for more than two months and he only just returned in the first week of August.
Overall, he has tossed 19 innings on the year but won’t be able to add to that total. A UCL sprain doesn’t necessarily always lead to surgery, but even the non-surgical recovery path requires a lengthy layoff. If he does require some kind of UCL surgery, that will likely wipe out his 2025 season, given the year-plus recovery times with such significant operations. If he’s able to avoid the surgeon’s table, he will be looking to return for a 12th straight MLB season. He has 427 career appearances with a 3.94 ERA.
Rockies Release Elias Diaz, Promote Drew Romo
3:10pm: The Rockies announced that Diaz has been given his unconditional release. He’s a free agent who can sign with any club at any point. Romo’s contract has indeed been selected from Triple-A Albuquerque in his place.
Colorado also reinstated left-hander Lucas Gilbreath from the 60-day injured list. A spot on the 40-man roster was already cleared by yesterday’s outright of Josh Rogers. Gilbreath has been out since undergoing Tommy John surgery in March of 2023.
1:55pm: In place of Diaz, the Rockies are expected to select the contract of catching prospect Drew Romo, reports Thomas Harding of MLB.com. He’ll presumably slot into the Rockies’ primary catching role down the stretch and audition for a potential long-term gig behind the plate in Denver.
1:45pm: The Rockies are releasing catcher Elias Diaz, whom they placed on outright waivers earlier this week, reports Daniel Alvarez Montes of El Extra Base. Once he’s cleared release waivers, he’ll be free to sign with any club. The new team would only owe Diaz the prorated league minimum for any time spent on the big league roster or injured list. The Rockies will be on the hook for the remainder of this season’s $6MM salary.
That Diaz is slated to be released is an indicator that no other club was willing to take on his remaining $1.45MM salary (plus the $50K fee for placing a waiver claim). Colorado could’ve simply kept Diaz on the roster and attempted to waive him again later this month when he was owed less money, but it seems they’ll instead part ways with the veteran backstop entirely, granting him extra time to settle in with a contending club down the stretch. Diaz had been in the final season of a three-year, $14.5MM contract with the Rockies and is a free agent at season’s end anyhow, so the move to release him appears to primarily be about affording him the ability to latch on with a contending club while also clearing time for a look at Romo.
Releasing Diaz now will naturally raise questions as to why the Rockies didn’t move Diaz for even a modest return at last month’s trade deadline. It’s a fair gripe on the surface, although it stands to reason that if Diaz went unclaimed when he’d cost other teams around $1.5MM in total, there probably wasn’t a robust trade market for him when he was owed more money and the Rockies were seeking prospect value in return.
It’s still plenty arguable that the Rox should’ve sold high on him at last year’s trade deadline or perhaps in the offseason, but the Rox instead added some modest pieces and entered this year with visions of a more competitive club than they’ve ultimately fielded.
Diaz, 33, is hitting .270/.315/.378 on the season. That’s a solid-looking line, particularly for a catcher, though metrics like wRC+ (80) and OPS+ (88) feel he’s been below-average at the plate after adjusting for the Rockies’ hitter-friendly home environment. Either of those marks is passable for a backstop with solid defensive grades, however, and Diaz is just that. He’s delivered markedly improved framing grades in 2024 and been credited with plus marks in Defensive Runs Saved (5) and Outs Above Average (5).
Diaz has never been a plus hitter outside of a strong 2018 showing with the Pirates, but he owns a .254/.306/.406 line over the past four seasons, during which he’s averaged 17 homers per 162 games played. He’s not an elite catcher but is a serviceable option who’s had his share of big league success and experience. At the very least, he’s an upgrade over the backup option for many postseason hopefuls. And as long as he signs with a new club on or before Aug. 31, he’ll be eligible for his new team’s postseason roster.
As for the 22-year-old Romo, he was the No. 35 overall pick by the Rockies back in 2020 and ranked among the game’s top-100 prospects as recently as the 2022-23 offseason. He’s considered to be a glove-first catcher but has shown more offense in the upper minors across the past two seasons, including a quality .297/.339/.499 batting line in a very hitter-friendly Albuquerque setting this season (103 wRC+).
Scouting reports at FanGraphs, Baseball America and other outlets praise the switch-hitting Romo as a plus defender with a plus arm but well below-average power. FanGraphs’ Eric Longenhagen noted that Romo had some uncharacteristic throwing issues last year (19% caught-stealing rate), but he’s bounced back in a big way with a heartier 29% rate in 2024.
With Diaz released and fellow backstop Jacob Stallings also playing on an expiring contract, Romo ought to be given a full run as the team’s starting catcher. Colorado doesn’t have any other near-ready catching prospects — Hunter Goodman can catch some, but they’ve used him more in the outfield — and certainly doesn’t have another one with Romo’s defensive chops.
Romo and Goodman could potentially shoulder the workload behind the plate down the stretch, depending on what comes of Stallings, who’s hitting .266/.367/.457 in 216 plate appearances while playing on a one-year, $2MM contract. Speculatively speaking, if the Rox are comfortable with Goodman collecting more playing time behind the plate, they could make a similar move with Stallings to the one they’ve made with Diaz.
Red Sox Designate Dominic Smith For Assignment
3:00pm: The Sox have formally announced Smith’s DFA and the reinstatement of Casas from the 60-day IL. Boston also reinstated Cooper Criswell from the injured list and optioned righty Chase Shugart to Triple-A Worcester.
2:10pm: The Red Sox will designate first baseman Dominic Smith for assignment today, reports Robert Murray of FanSided. Smith’s DFA will presumably clear the way for Triston Casas to be reinstated from the 60-day IL — as has been previously reported — and reclaim the everyday first base job in Boston.
Smith opted out of a minor league deal with the Rays back on May 1 when a big league spot with the Red Sox became available in the wake of Casas’ injury. He’s hardly replaced the offensive contributions that Casas can offer, but Smith hasn’t been too far off a league-average bat in Boston, slashing .237/.317/.390 with six homers and 20 doubles in 278 plate appearances. By measure of wRC+, he’s only been about 5% worse than average at the dish.
Still, for an offensively inclined position like first base, that’s not much production — particularly since Smith also grades out as an average defender at best. Defensive Runs Saved had him as a positive last year but pegs him at -2 in 2024. Statcast’s Outs Above Average has had him slightly above-average in each of the past three seasons but below-average in his career overall. It’s fair to suggest Smith has improved his glovework over the years, but he’s still not a standout defensive player at his position.
Now that he’s been designated for assignment, Smith will be either outrighted or released. It’s unlikely he’ll be claimed by another club, but he could latch on elsewhere on a new deal once he clears waivers. The Red Sox would be responsible for the remainder of his contract, minus the prorated minimum for any time spent on his new club’s big league roster/injured list.
Smith hasn’t lived up to his former top prospect billing, but he did have an impressive 2019-20 run that saw him slash .299/.366/.571 with 21 homers in 396 plate appearances. His bat has cratered with a .242/.312/.361 output in the four seasons since that time — numbers that roughly align with his results during his 84-game stint with the Red Sox. Smith reached six years of big league service while with the Sox, so he’ll be a free agent again at season’s end regardless of who signs him for the season’s final few weeks.
Yankees Select Tim Mayza
The Yankees announced that they have selected the contract of left-hander Tim Mayza. They signed the lefty to a minor league deal after he was released by the Blue Jays last month. They optioned Will Warren after Wednesday’s game and designated Enyel De Los Santos earlier this week, meaning they already had a vacancy on both the active and 40-man rosters.
It’s been a strange year for Mayza, who had a strong run for the Jays before everything seemed to come off the rails this year. From 2017 to 2023, he made 317 appearances for the Jays, despite missing the 2020 season while recovering from Tommy John surgery. In that stretch, he allowed 3.47 earned runs per nine innings. He struck out 25.7% of batters faced, walked just 7.8% of opponents and got ground balls on 54.4% of balls in play. He racked up four saves and 77 holds in that period.
But here in 2024, his 35 appearances for the Jays were disastrous, leading to an 8.04 ERA. He surely wasn’t helped by a .367 batting average on balls in play or his 54.8% strand rate, but he also only struck out 13.2% of batters faced.
He was designated for assignment by the Jays at the end of June. Since he had passed five years of service time this year, he earned the right to reject an outright assignment while retaining his $3.59MM salary. The Jays skipped that formality and released him, leaving them on the hook for the rest of that money.
The Yankees signed him to a minor league deal and sent him to Triple-A Scranton/Wilkes-Barre. He has since made nine appearances for the RailRiders, allowing two earned runs in 8 1/3 innings. He has struck out eight opponents against three walks.
That will get him another shot in the big leagues, giving manager Aaron Boone a second left-handed option alongside Tim Hill. Now that Mayza has more than five years of service, he can’t be optioned to the minors without his consent. But if he manages to stick around, he can be retained via arbitration for the 2025 season.
For now, it’s a fairly low-risk move, as the Yankees will only have to pay Mayza the prorated league minimum for any time spent on the roster. That amount will be subtracted from what the Jays pay, which will make a small dent in their competitive balance tax calculation. Last week, Blue Jays president and CEO Mark Shapiro said the Jays were just under the tax line but that the situation was “fluid”.
Nationals Outright Jordan Weems
The Nationals announced Friday that right-hander Jordan Weems cleared outright waivers and has been assigned to Triple-A Rochester. He was designated for assignment a couple days back. Weems has the right to reject the assignment in favor of free agency, should he choose.
The 31-year-old Weems has logged 136 innings out of the Nats’ bullpen dating back to 2022, sandwiching a sharp 2023 campaign between a pair of tough seasons in 2022 and 2024. He’s been tagged for a grim 6.70 ERA with career-worst 17.9% and 12.2% strikeout and walk rates, respectively, in 2024. He’s just one year removed from a 3.62 earned run average, 25.9% strikeout rate and 12.1% walk rate in 54 2/3 innings, however. In 155 2/3 career innings between the A’s, D-backs and Nats, Weems has a 5.26 ERA.
Now that he’s cleared waivers, Weems can choose between free agency and reporting to Rochester. If he stays in the Nats organization, he’d have the right to become a minor league free agent at season’s end anyhow, as is true of all players with three-plus years of service who are outrighted off a major league roster and not added back by the end of the season.
Red Sox Expected To Activate Triston Casas
The Red Sox are expected to reinstate first baseman Triston Casas from the 60-day injured list today, reports MassLive.com’s Chris Cotillo. The slugger should be back in the lineup for tonight’s matchup with the Orioles and ace Corbin Burnes.
Casas, 24, had a slow start in 2023 before finding his stride with a breakout five-month finish to last season. He largely picked up where he left off early in 2024, popping six homers in 90 plate appearances and slashing .244/.344/.513 before sustaining fractures on the left side of his ribcage and enduring a lengthy shutdown from baseball activities. The Sox have eased Casas back into action with an 11-game run in Triple-A Worcester, during which he’s turned in a hearty .300/.404/.550 slash in 47 trips to the plate.
The return of Casas should provide a thunderous boon to a Sox lineup that has received middling production from Dominic Smith in his absence. Smith hasn’t been an abject liability but has turned in a tepid .237/.317/.390 batting line that checks in 5% worse than league average, by measure of wRC+. Others like Romy Gonzalez, Garrett Cooper and Bobby Dalbec have filled in at times but have struggled to produce overall. (Cooper is no longer with the organization.)
While Casas’ return isn’t likely to turn the tides in the division race — at least not directly, though he could certainly impact the Orioles/Yankees battle for first place — he could very much be a difference-maker in Boston’s pursuit of a Wild Card berth. The Red Sox are eight games behind the Yankees and O’s, who are tied for the AL East lead, but they’re a more manageable 2.5 games back in the hunt for the third Wild Card slot. Getting a legitimate 30-homer bat back into the middle of the lineup — Casas has popped 30 homers while batting .260/.363/.493 in 154 games dating back to last season — has major ramifications for the remainder of the Red Sox’ schedule.
Casas is on the 60-day injured list, so Boston will need to make a corresponding 40-man roster move in order to reinstate their prized young slugger. They don’t have an obvious candidate to replace him on the 60-day IL, unless they’ve quickly determined that James Paxton‘s partial calf tear is indeed a season-ender, so a DFA or waiver placement could be in the offing.
Astros To Promote Shay Whitcomb
The Astros are planning to select Shay Whitcomb from Triple-A, reports Ari Alexander of KPRC 2 Houston. He has played all over the diamond for the Sugar Land Space Cowboys this season, seeing the bulk of his time at second base, third base, and shortstop. However, his best path to playing time with the Astros will be as a first baseman and occasional corner outfielder and DH. The team will need to make a corresponding move to free up space for Whitcomb on the 40-man roster.
Whitcomb, now 25, joined the Astros organization as the final pick in the shortened 2020 draft. Exclusively a shortstop during his time at UC San Diego, he has also played plenty of second and third base at every level in the minors. In 2024, he began seeing more playing time at first base and the outfield corners, presumably because second base (Jose Altuve), third base (Alex Bregman), and shortstop (Jeremy Peña) are all currently blocked at the big league level. While Whitcomb’s glove might be more valuable at second, third, or short, he has performed well enough at Triple-A this year (25 HR, 26 SB, 122 wRC+) that it’s worth seeing if he can team up with Jon Singleton to make a productive first base platoon. Singleton has played 77 games at first base for the Astros this year, and while he has a 113 wRC+ against right-handed pitching, he is all but unplayable against southpaws (32 wRC+ in 71 PA). The righty-batting Whitcomb has relatively neutral platoon splits at Sugar Land this year, with an .890 OPS against righties and a .979 OPS against lefties.
Earlier this month, Astros GM Dana Brown suggested the team would call up either Zach Dezenzo or Whitcomb to help out at first base. Just two days later, Denzenzo made his MLB debut. While Dezenzo, 24, is a more highly regarded prospect than Whitcomb, the former has had a rough go of it so far with Houston, going just 5-for-25 with a .591 OPS and 64 wRC+. Yet, although Whitcomb’s promotion comes on the heels of Dezenzo’s struggles, manager Joe Espada could still find playing time for both, considering how badly the Astros could use a productive right-handed bat at first and in the outfield.
KBO’s Samsung Lions Sign Lewin Diaz
The Samsung Lions of the Korea Baseball Organization announced this week that they’ve signed first baseman Lewin Díaz (relayed on X by Dan Kurtz of MyKBO). The CAA Sports client receives a $50K salary with up to $20K in incentives for the stretch run. The Lions also paid a $100K release fee to the Diablos Rojos del Mexico, the Mexican League team with which Díaz had been playing. Samsung waived outfielder Ruben Cardenas in a corresponding move.
Díaz, 27, was an MLBTR staple during the 2022-23 offseason. He changed teams via waivers or minor trade four times that winter. The Orioles eventually succeeded in sneaking him through waivers and kept him in Triple-A for all of last season. Díaz had a decent year in the minors, hitting .268/.362/.442, but never got an MLB look from Baltimore. He qualified for minor league free agency over the winter and signed a non-roster deal with the Nationals.
Washington released Díaz at the end of camp. He didn’t land another affiliated deal, instead making the move to Mexico. The left-handed hitter has mashed at a .376/.452/.647 clip with 19 homers across 75 games in that very hitter-friendly league.
Díaz was a fairly well-regarded prospect with the Twins early in his pro career. Minnesota dealt him to the Marlins as part of a deal for reliever Sergio Romo in 2019. Díaz didn’t hit major league pitching over parts of three seasons in Miami, running a .181/.227/.340 slash in 112 games. He has been an above-average Triple-A batter, posting a .258/.341/.479 mark in nearly 1200 plate appearances at the level.
Tigers To Promote Jace Jung
The Tigers are calling up top infield prospect Jace Jung from Triple-A Toledo, reports Evan Petzold of the Detroit Free-Press. The 12th overall pick of the 2022 draft will make his major league debut tomorrow evening against the Yankees.
Jung joins what’ll be a suddenly younger Detroit infield. The Tigers are also bringing up deadline acquisition Trey Sweeney, a 2021 first-round pick whom they acquired in the Jack Flaherty deal. That duo will join rookie second baseman Colt Keith as the Tigers evaluate young players who could be key pieces of next year’s team. Keith has had an up-and-down debut campaign at the keystone, as he’s had very poor months of April, June, and August around huge performances in May and July.
Once Detroit moved Keith from third to second base, they slid Jung to the hot corner. He has started 68 games there this season against 17 starts at second base, which had been his primary position at Texas Tech and for his first two years in pro ball. Detroit has used Gio Urshela as their primary third baseman. His bat has started to come around following a rough first half, but the Tigers seem to be turning their attention toward next season. Despite an ongoing four-game win streak, they’re 7.5 back of the American League’s last playoff spot.
Jung, the younger brother of Rangers third baseman Josh Jung, adds a high-upside offensive talent. He ranks fourth among Detroit prospects and 75th overall on Baseball America’s most recent ranking of the farm system. BA credits the left-handed hitter with plus power and a patient approach. While there’s some concern about his pure hit tool, the walks and power give him a chance to hit in the middle third of a lineup.
The 23-year-old is having a nice season in Toledo. He’s hitting .257/.377/.454 with 14 homers, 23 doubles and a triple through 415 plate appearances. Jung is drawing walks at a massive 16.1% clip while striking out at a roughly average 22.4% rate. While he has fallen into a bit of a slump of late, Jung has hit very well with the platoon advantage over the course of the season. He’s hitting .272/.402/.510 in 321 plate appearances against righty pitching.
Jung has predictably had a tougher time with left-handed arms. Detroit has a few righty-hitting infielders who could take some starts against southpaws, but Jung figures to play regularly over the season’s final six weeks. Urshela is on a one-year free agent deal and always felt like a bridge until Jung was ready to take over at third base. The Tigers should give him near everyday reps to gauge whether they can pencil him in as their starter going into 2025.
Jung will not come close to a full year of service or the time necessary to reach early arbitration as a Super Two player. He’s under team control for at least six seasons beyond this one and won’t get to arbitration for three years. A future optional assignment to Triple-A could push that timeline back.
The timing of Jung’s promotion, likely not coincidentally, comes just after the cutoff for him to preserve his rookie eligibility going into next season. From tomorrow, there’ll be 45 days remaining on the regular season calendar. A position player remains a rookie so long as they’ve spent 45 days or fewer on an MLB active roster and have not topped 130 at-bats. So long as the Tigers keep him below the at-bat threshold, Jung would be eligible for Rookie of the Year consideration going into next season.
That’s a relevant factor thanks to the Prospect Promotion Incentive introduced in the most recent round of collective bargaining. A team can earn a bonus draft pick if they carry a rookie top prospect (one who made the offseason Top 100 on at least two of the lists at Baseball America, ESPN, and MLB Pipeline) for a full service year. If that player wins Rookie of the Year or finishes in the top three in MVP balloting during his pre-arbitration seasons, the team would get an extra pick after the first round of the following draft.
Jung could be in consideration for the prospect criteria, as evidenced by his placement on BA’s current Top 100. There’s no guarantee he’ll make two of the three lists next winter — and it’s certainly not a lock that he’ll win Rookie of the Year — but the Tigers would at least keep the possibility open if they plan for Jung to break camp in 2025. The Cardinals timed their promotion of top shortstop prospect Masyn Winn right at this time last season, for instance.
Sweeney isn’t the same caliber of prospect, but Detroit could give him a look at shortstop in place of the struggling Javier Báez. They’ll need to add both players to the active and 40-man rosters. They don’t have any obvious candidates to land on the 60-day injured list, so they might need to designate multiple players for assignment tomorrow.

Mets Sign Eddie Rosario To Minor League Deal
The Mets signed outfielder Eddie Rosario to a minor league contract, the team’s Triple-A club with Syracuse announced this evening. Pat Ragazzo of Sports Illustrated first reported the agreement on Tuesday (X link). The veteran outfielder elected free agency after being designated for assignment by the Braves over the weekend.
Rosario is now on his third NL East club of the season. He began the year on a minor league deal with the Nationals. Rosario broke camp with Washington, securing a $2MM base salary in the process, and went on to play 67 games. He hit just .183/.226/.329, sandwiching a solid performance in May with almost no production in April or June. The Nats cut Rosario loose when they promoted top prospect James Wood at the start of July.
Atlanta then circled back to their old left fielder. The Braves inked Rosario to a minor league pact and almost immediately called him up. It never seemed likely that Atlanta would get the kind of hot streak that helped propel them to a World Series title three years ago. They were presumably hoping for something close to last year’s league average .255/.305/.450 showing. Rosario’s return to Truist Park did not reinvigorate his bat. He hit .154/.181/.282 through 84 trips to the plate before being released.
This has been a career-worst showing for the 10-year MLB veteran. Rosario carries a .175/.215/.316 slash in 319 plate appearances between the two teams. No hitter with 300+ PAs has a lower on-base mark. Only Mitch Garver (.167) has a lower average, while Rosario is seventh from the bottom in slugging. That makes it difficult for a team to continue affording him big league opportunities, but there’s no downside for New York in taking a minor league flier. Rosario has been a very streaky hitter throughout his career, so the Mets can give him some time with Syracuse to see if he can find his form.
Regardless of whether he makes it to the big leagues in Queens, Rosario will be a free agent next offseason. It’s a depth pickup for the stretch run for a team that is just a game out of the playoff race. The Mets have Brandon Nimmo, Harrison Bader and Jesse Winker as their primary outfield. J.D. Martinez is locked in at designated hitter, while Tyrone Taylor is working as the fourth outfielder. Lefty-hitting Ben Gamel is on the roster as a fifth outfielder/bench bat, while DJ Stewart is on optional assignment to Syracuse. Barring injury, Rosario would presumably need to outplay both Gamel and Stewart to get an opportunity at Citi Field.
Rosario would be eligible for postseason play with New York. A player can participate in the playoffs so long as they’re in that organization by September 1. It is not necessary for the Mets to call Rosario up before that date to get him on the postseason roster; the league routinely allows teams to call players up as injury substitutes if they were playing on a non-roster contract by the start of September. Rosario would really need to catch fire to make that a consideration even if the Mets snag a Wild Card spot.
