Rockies Release Austin Gomber
The Rockies have released veteran lefty Austin Gomber, per a team announcement. (Thomas Harding of MLB.com reported the move just minutes prior to its announcement.) He was reportedly placed on outright waivers earlier this week. Given that he’s now being released, it’s clear he wasn’t claimed. Colorado will give his 40-man spot to lefty reliever Lucas Gilbreath, whose contract has been selected from Triple-A Albuquerque. The Rox also placed righty Dugan Darnell on the 15-day injured list due to inflammation in his left hip and recalled righty Angel Chivilli from Triple-A.
Gomber, 31, was the lone remaining player from the Rockies’ return in their trade of Nolan Arenado to the Cardinals. He was only a few weeks from reaching free agency anyhow, as he crossed six years of major league service earlier in the season, but he’ll now head to the open market a bit earlier than previously scheduled.
A shoulder injury kept Gomber on the injured list from Opening Day into mid-June. He’s since made 12 starts and struggled more than he has at any point in his career. Gomber has been a fifth starter over his time with the Rockies, pitching to a middling 5.08 ERA in 544 innings from 2021-24, but he’s been tattooed for a 7.49 earned run average in 57 2/3 innings with the Rockies in 2025.
Though he’s never thrown hard, Gomber’s average fastball this year is sitting at a career-low 89.5 mph. That’s down one mile from last year and down a bit more than two miles per hour over his first season with Colorado back in 2021. His already low strikeout rate has bottomed out at a career-worst 12.5%, and his 7.2% swinging-strike rate is tied (with teammate Antonio Senzatela) for ninth-worst among the 257 pitchers who’ve tossed at least 50 innings in 2025.
Despite Gomber’s sub-par results through his four seasons in Denver, the Rockies opted to tender him a contract this past offseason. He’s being paid $6.35MM this season, with about $1.26MM of that sum yet to be paid out over the final month-plus of the year. The Rockies will remain on the hook for the entirety of that amount, minus the prorated league minimum for any time Gomber may spend on another team’s big league roster.
Gilbreath, 29, posted solid numbers with Colorado in his first two seasons from 2021-22: 85 2/3 innings pitched, 16 holds, one save, 3.78 ERA, 25% strikeout rate (albeit with an ugly 13.2% walk rate). He looked like he’d carved out a role in the Rockies’ bullpen, but a UCL tear during spring training in 2023 wiped out his entire season and limited him to just one big league inning in 2024. The Rockies passed him through waivers earlier this season, and he’s now back in the majors for the first time this year and will look to get back into just his second MLB game since the conclusion of the 2022 campaign.
It’s been a tough year for Gilbreath in Albuquerque. Granted, that’s an extremely hitter-friendly setting, but a 6.21 ERA, 11.8% walk rate and 1.91 HR/9 rate can’t solely be blamed on league environment. He’s been a bit better of late (5.29 ERA in his past 17 innings), but the results still aren’t all that encouraging — nor is the fact that a heater that averaged 93.8 mph in 2022 is now sitting 89.8 mph three years and one major surgery later. Be that as it may, he’ll be summoned to the majors to give the Rockies a fresh arm and perhaps to audition for a 2026 spot in the season’s final few weeks.
Diamondbacks Designate Jose Herrera For Assignment
The D-backs have designated catcher Jose Herrera for assignment, reports Steve Gilbert of MLB.com. His spot on the roster will go to fellow catcher Gabriel Moreno, who is being reinstated from the injured list.
Herrera, 28, has been a backup behind the plate for the Snakes dating back to 2022. He’s never provided much with the bat, hitting only .200/.280/.259 (53 wRC+) in 562 plate appearances over the course of 190 big league games. He was outstanding at thwarting opposing runners on the basepaths in his first two seasons but has slipped in that regard over the past two years and now has a league-average 21.8% caught-stealing rate in his career. Herrera typically hasn’t drawn plus framing grades but does have solid blocking skills, per Statcast.
This year’s 204 plate appearances are a career-high at the MLB level for Herrera — due primarily to the aforementioned Moreno injury. Moreno, the 2023 NL Gold Glove winner, suffered a broken finger earlier this summer and has been out for more than two months. He’s hitting .187/.285/.259 in that time with a pair of home runs (the only multi-homer season of his big league career thus far).
Shortly after Moreno hit the injured list, the D-backs signed veteran catcher James McCann, who’d been on a minor league deal with the Braves. McCann has hit the ground running with the Diamondbacks, hitting .247/.337/.403 with three home runs. That performance has been enough to earn him the backup job to Moreno for the remainder of the season, it seems. McCann will be a free agent at the end of the year, so he’s not a long-term backup partner unless the D-backs choose to re-sign him, but he’s clearly leapfrogged Herrera on the depth chart at this point.
Reds Select Zach Maxwell
The Reds announced Friday that they’ve selected the contract of right-hander Zach Maxwell from Triple-A Louisville. Fellow righty Ian Gibaut, who’s been out since late June due to a shoulder impingement, was transferred from the 15-day IL to the 60-day IL to create space on the 40-man roster.
Maxwell, 24, was Cincinnati’s sixth-round pick out of Georgia Tech back in 2022. The hulking 6’6″, 275-pound righty ranked 24th among Reds prospects on the post-draft updates from both Baseball America and MLB.com. He’s spent the entire season in Triple-A so far, tossing 49 2/3 innings out of the bullpen and recording a 4.17 earned run average. Maxwell boasts a plus-plus fastball and slider/cutter, per those scouting reports, with Baseball America noting that he can “look unhittable” when his command is dialed in.
That’s a prominent caveat, however. Maxwell has poor command and has struggled with walks dating back to his college career, when he walked a combined 20.6% of his opponents in his final two years before being drafted. He’s scaled that back a bit, but he’s still doled out a free pass to an untenable 14.5% of opponents this year in Louisville.
Maxwell can miss bats in droves, as one would expect from a massive righty whose velocity climbs as high as 102 mph (and likely appears even faster to opponents, given the extension he can get on a 6’6″ frame). If he can continue to make incremental gains with his command — he’s scaled back from a 16% walk rate in ’24 to this year’s 14.5% mark — he has the makings of a formidable late-game bullpen weapon. It’s a similar skill set to another towering Reds righty, the 6’5″ Luis Mey, though Mey uses a sinker as his primary offering rather than a four-seamer. The Mey/Maxwell pairing could potentially be lethal at the end of Reds games, but both will need to improve their command to reach their ceilings. Mey was optioned to Louisville last night, and Maxwell is taking his spot on the active roster.
Maxwell will be auditioning for a future bullpen spot in the final five weeks or so of the season (while, of course, also trying to help push the team into the postseason). Emilio Pagan is a free agent at season’s end, while other veterans like Scott Barlow and Brent Suter both have club options. The former seems unlikely to be picked up, though the latter could well return, given his Cincinnati roots and the option’s affordable net $2.75MM price point. Either way, there are some potential openings in the 2026 ‘pen that could be claimed by some of the organization’s young arms.
Marlins Place Cal Quantrill On Outright Waivers
Marlins right-hander Cal Quantrill is currently on outright waivers, reports Ken Rosenthal of The Athletic. Outright waivers are a 48-hour process, with priority determined based on a worst-to-first look at the leaguewide standings. The Rockies have Major League Baseball’s worst record and thus have first priority, while the blistering-hot Brewers have the lowest priority at the moment.
Quantrill, 30, signed a one-year, $3.5MM contract with the Marlins over winter and will be a free agent at season’s end. As of this writing, there’s about $753K yet to be paid out on that salary (although Quantrill’s contract does contain a modest $500K worth of total incentives). Any team that claims him would be required to take on the remainder of that contract.
Overall, Quantrill’s 5.50 ERA and rate stats aren’t much to look at. He’s fanned only 17.4% of his opponents, and his 34.2% ground-ball rate is a career-low. Quantrill’s 6.4% walk rate is his best since 2022, but he’s served up 1.40 homers per nine innings — tied for the worst mark of his career. Opponents have averaged 90.4 mph off the bat with an 11.6% barrel rate and 43.9% hard-hit rate. All are career-worsts.
Nearly all of Quantrill’s struggles, however, were back in April and in his three August starts thus far. From May 6 through July 30, Quantrill tossed 71 innings with a 3.55 ERA, 21.3% strikeout rate and 5.6% walk rate. That sort of production would be a bargain, particularly at Quantrill’s price point.
Few, if any, contending clubs are going to look at Quantrill and view him as a postseason-caliber starter. Playoff contenders who’ve run into some poor injury luck recently and simply need back-of-the-rotation innings could consider placing a claim.
Quantrill has never been an ace or a particularly hard thrower, but he’s a former No. 8 overall draft pick with a lifetime 4.26 ERA in 828 2/3 innings as a big leaguer. Most of that success came with the Guardians in 2021-22, however. Quantrill has just a 5.21 ERA dating back to 2023, though that previously mentioned May through July stretch stands as one of the strongest of his career. This year, he’s sitting 93.6 mph on his four-seamer, which is just one of six different pitches he’s thrown at at least an 8.7% clip. He’s also used a cutter, splitter, sinker, slider and curveball to try to keep opponents off balance.
Notably, Quantrill has struggled against right-handed opponents but overwhelmed lefties. Opposing left-handed hitters have posted an awful .209/.275/.335 slash in 209 plate appearances against Quantrill this season. He has more even splits for his career at large, but this year’s changes to his pitch selection — career-high four-seam usage, career-low sinker usage and the reintroduction of a slider he scrapped in early 2021 — have produced a pronounced preference for facing southpaw hitters. Opposing righties have torched Quantrill for a .337/.379/.605 batting line.
If Quantrill passes through waivers unclaimed, the Marlins can choose to assign him outright to a minor league affiliate but are not obligated to do so. They can simply return him to the active roster and continue playing out the season with him on the staff. Quantrill has enough service time to reject a minor league assignment in favor of free agency and still retain the remainder of his guarantee. As of right now, he’s scheduled to start Friday’s game against the Blue Jays and the returning Shane Bieber.
Mets Place Francisco Alvarez On Injured List
2:45pm: Alvarez is now officially on the IL due to a right thumb sprain with Senger recalled. The Mets say Alvarez will be further evaluated in 10-14 days.
11:13am: The Mets will place catcher Francisco Alvarez on the injured list today due to his right thumb injury, reports Joel Sherman of the New York Post. An exact diagnosis isn’t clear just yet, but Alvarez exited Sunday’s game early after injuring his hand on a slide into second base. Manager Carlos Mendoza noted that night that Alvarez was headed for an MRI to evaluate the extent of the injury (link via The Athletic’s Tim Britton).
Losing Alvarez for any period of time is a crushing blow to a flailing Mets club that has come out of the All-Star break with an 11-16 record — including just a 4-11 mark in August. The 23-year-old backstop has been the team’s hottest hitter after a monthlong reset in Triple-A. He’s come to the plate 71 times since being recalled on July 21 and turned in a brilliant .323/.406/.645 batting line (193 wRC+) with four homers, six doubles and a triple.
With Alvarez out for at least the next nine days — his stint can be backdated to Monday — the Mets will have to lean on backup Luis Torrens and rookie Hayden Senger behind the dish. It’s a notable offensive downgrade, with Torrens hitting just .214/.280/.301 in 225 plate appearances this season and Senger carrying a .174/.208/.196 slash in 49 plate appearances as a 28-year-old rookie.
Alvarez missed significant time in 2023 with a thumb injury, though that was due to a ligament tear in his other (left) thumb. He’s also missed time due to a fractured hamate in his left wrist. While it’s perhaps the smallest of silver linings that this latest injury didn’t occur in the same hand that’s already caused him to miss significant action on two separate occasions, his absence will be prominently felt.
Phillies Designate Josh Walker For Assignment, Activate José Alvarado
The Phillies announced that left-hander José Alvarado has been reinstated from the restricted list. That move was expected as he had served his 80-game PED suspension. To make make room for him, the Phils optioned right-hander Nolan Hoffman to Triple-A Lehigh Valley and designated left-hander Josh Walker for assignment.
Walker, 30, was acquired from the Jays in exchange for cash back in May. He pitched five innings with Toronto but hasn’t appeared in the majors with Philadelphia. Rather, he’s spent his entire time with the Phillies organization in Triple-A Lehigh Valley, where he’s logged 26 innings with a 4.50 ERA, 19.8% strikeout rate and 10.8% walk rate.
A towering 6’6″ left-hander, Walker has appeared in parts of three big league seasons — two with the Mets and earlier this year with the Jays. He’s pitched only 27 1/3 MLB frames, however, and sports a rocky 6.59 ERA in that limited sample of work. He’s fanned nearly one quarter of his opponents and has a sharp 12.4% swinging-strike rate, but command has been a struggle for him both in the majors and in the upper minors. That said, Walker does have a more palatable 4.46 ERA and 26% strikeout rate in 167 2/3 innings of Triple-A work.
Alvarado has been out since May 16 after receiving an 80-game ban following a positive PED test. His absence subtracted one of the Phillies’ top relief arms, and he’ll return to a new-look bullpen that suddenly looks like a powerhouse. In Alvarado’s absence, the Phillies acquired Jhoan Duran from the Twins and signed free agent David Robertson. That pair, combined with Matt Strahm, Orion Kerkering, Tanner Banks and the returning Alvarado, makes the Phillies’ relief corps both exceptionally deep and dangerous for opposing lineups.
In 20 innings prior to his suspension, Alvarado pitched to a 2.70 ERA with a 29.8% strikeout rate and just a 4.8% walk rate. While he had some struggles last year (4.09 ERA), Alvarado has generally been a high-impact bullpen weapon for skipper Rob Thomson for the past several seasons. Dating back to 2022, he’s pitched 174 major league innings and logged a 3.10 ERA, 32% strikeout rate, 10.2% walk rate and 50.5% grounder rate.
Despite being on the restricted list, Alvarado was allowed to pitch in a minor league rehab stint as a tune-up to return to the Philadelphia bullpen. He tossed five shutout innings, albeit with as many walks as strikeouts. Alvarado recorded a huge 62.9% ground-ball rate in that time. His average sinker dipped from 99.3 mph to 98 mph, though that’s not exactly a surprise given the lengthy layoff.
While Alvarado will provide a major boost to the Phillies down the stretch, he’ll be a non-factor when the postseason rolls around. Players who are suspended for PED usage are ruled ineligible for the playoffs during the year in which they served their suspension. Thomson will have Alvarado at his disposal for the next six weeks, but in October, it’ll be Duran, Robertson, Strahm, Banks and Kerkering anchoring the bullpen — perhaps alongside one of the current rotation members, depending on the health and performance of the group between now and late September.

Doug Sisk
- What happens to Frankie Montas’ 2026 player option if the Mets release him before the end of the 2025 season?
Steve Adams
- The player option is guaranteed money. He’d make next year’s $17MM and count against the luxury tax whether he’s on the roster or not.
OsKnows
- Mountcastle’s time as an O almost over?
Steve Adams
- I do think he’ll be traded this offseason (or perhaps just non-tendered if he really struggles down the stretch, but he’s hitting well since returning from the IL anyhow). I’d expect first base to primarily be a combination of Mayo and Basallo next year. Mountcastle only has one year of club control left and will probably make more than $8MM. O’s can move him and put that money toward pitching instead.

- Greetings!
- Let's begin
RAGBRAI
- Does Gallen get a QO from AZ and if so does he take it? What would he get on the open market with a respectable ROS?
Steve Adams
- They'll give him a QO. His decision probably hinges somewhat on how he finishes, though I expect him to decline it. Gallen feels like he's going to be the next relatively high-profile starting pitcher/Boras client to sign a two-year deal with an opt-out. If he finishes poorly enough, maybe he accepts or (more surprisingly) doesn't get a QO. But I think if the D-backs saw any real scenario where they wouldn't give him the qualifying offer, he'd have been traded in July.
- Obviously, a major injury changes that calculus, but short of that, I'd be surprised if he doesn't get one.
- If he accepts that, it's not the end of the world. They paid Jordan Montgomery $22MM not to throw a pitch for them in 2025. A similarly priced gamble on a Gallen rebound isn't a terrible bet.
Brad
- How many major league free agent contracts have surplus value? I feel like the percentage is much lower than you think.
Steve Adams
- By definition, very few of them are going to provide surplus value. Free agency is an auction, and most teams tap out of the bidding because they feel the price has exceeded the player's value. On some one-year deals or some mid-range free agent deals, you can find some bargains, but it's only natural for the weightier free-agent deals to come in to provide minimal surplus value -- if any at all.
JM
- Why can a player stay under club control after he's released and granted free agency? For instance (if reports are correct), Nathaniel Lowe is a free agent and will sign today with the Red Sox, after the Nats DFAed and released him upon clearing waivers. But those same reports say the Sox will have a final arb year of club control in 2026 (though likely non-tender him anyway). Once a free agent (after a release or a non-tender), not always a free agent?

Red Sox Designate Ali Sánchez For Assignment
1:57pm: The Sox have now officially signed Lowe and designated Sanchez for assignment. They also placed outfielder Rob Refsnyder on the 10-day injured list, retroactive to August 15th, due to a left oblique strain and recalled infielder/outfielder Nate Eaton.
1:26pm: The Red Sox will designate catcher Ali Sánchez for assignment today, reports Chris Cotillo of MassLive.com. The team has yet to announce the move, but they’ll need roster space for their reported agreement with veteran first baseman Nathaniel Lowe.
Sánchez, 28, appeared in only one game with the Red Sox and was hitless in his lone plate appearance. He was 5-for-21 with a couple doubles as a member of the Blue Jays before landing in Boston via waivers after being designated for assignment. Sánchez has appeared in parts of four major league seasons and suited up for five teams but has just 132 plate appearances in 47 games overall. He’s a .185/.222/.235 hitter in that tiny sample of scattershot playing time.
Unsurprisingly, Sánchez’s work in the upper minors has been far better. He’s played in parts of six Triple-A seasons and carries a .269/.340/.399 slash in 1266 trips to the plate. He’s a better-than-average defender who excels at blocking balls in the dirt and boasts a superlative 39% caught-stealing rate in his 12-year professional career.
Sánchez is out of minor league options, so any team that claims him off waivers will have to plug him right onto the big league roster. Waivers are the Red Sox’ only possible course of action with Sánchez, now that the trade deadline has passed. He’ll be placed on outright or release waivers within the next five days (very likely the former). He’s been outrighted multiple times in his career, so if Sánchez clears waivers, he’d be able to reject a minor league assignment in favor of free agency
White Sox Outright Jacob Amaya
Aug. 18: Amaya went unclaimed on waivers and has been assigned outright to Triple-A Charlotte, per James Fegan of Sox Machine.
Aug. 15: The White Sox announced Friday that they’ve designated infielder Jacob Amaya for assignment. His spot on the roster goes to fellow infielder Chase Meidroth, who has been reinstated from the 10-day injured list.
Amaya, 26, has appeared in 37 games for the South Siders this season. He’s played decent middle infield defense, primarily at shortstop, but has mustered an anemic .106/.139/.121 batting line in 73 trips to the plate. He’s out of minor league options, so the Sox didn’t have the ability to simply send him to the minors without first passing him through waivers.
This is the second DFA of the season for Amaya and his third DFA of the calendar year. The Sox passed him through waivers back in May, outrighted him to Triple-A, and then selected him back to the big league roster earlier this month. Amaya has seen time in parts of three big league seasons but struggled at the plate with the Marlins, Astros and ChiSox. He’s a career .147/.183/.161 hitter in 154 major league plate appearances but carries a more respectable .250/.348/.388 line in 1351 Triple-A plate appearances.
The White Sox will place Amaya on waivers within the next five days. If he goes unclaimed, he’ll have the right to reject an outright assignment to Triple-A in favor of free agency.
