Kotsay: Mason Miller “Unavailable Tonight,” Not Injured
Athletics closer Mason Miller was “unavailable tonight,” according to manager Mark Kotsay, who also said the decision was not injury-related. The A’s held a 5-3 lead over the Mariners entering the ninth inning at Sutter Health Park tonight and elected to stick with rookie Jack Perkins rather than go to the flamethrowing closer Miller, who hasn’t pitched since Saturday. The heavy implication is that a trade may be in the works for Miller, who is known to be of interest to the Padres and Yankees among others.
The Mets and Phillies were linked to Miller earlier today. The Phillies have since acquired Jhoan Duran from the Twins, while the Mets subsequently added Tyler Rogers and Ryan Helsley (plus Gregory Soto five days ago). The list of potential suitors for Miller is likely extensive, though the young talent required to get him will be significant.
Miller, 27 in August, is under team control through 2029. He’s also one of the game’s best relievers. Miller’s 39.1 K% ranks second among all relievers, as does his average fastball velocity of 101.2. Some might say Miller has slipped a bit from last year’s breakout All-Star performance, but his 3.76 ERA in a 38 1/3 inning sample will hardly deter interested GMs. Miller’s walk rate has worsened, and he’s been barreled up a good amount this year, but he’s still an impact stopper who’s under control for four-plus years.
In Tim Dierkes’ mailbag last week, he attempted to find comps for a reliever of Miller’s caliber being traded. Tim concluded, “Even going back a decade to identify those comps, there’s not a great match for Miller, trading one of the game’s best relievers at the deadline with four-plus years of control remaining. Unless the waters are muddied with, say, Luis Severino’s contract, I’d expect two very good 55/60 grade prospects, and perhaps an equivalent player with MLB experience, to be required.”
As J.J. Cooper of Baseball America outlined yesterday, typically about three top-100 prospects are traded at the deadline each year. We’ve seen one thus far, with #50 Eduardo Tait heading to Minnesota to headline the Duran deal. Mick Abel, the secondary piece in that trade, “very much is on the very cusp of the Top 100” according to Cooper. Keep in mind that Duran is under team control for two-plus years, while Miller is under control for four-plus. Miller’s arbitration salaries will only begin next year.
We haven’t seen a top-25 prospect traded since the Padres included a pair in the 2022 Juan Soto deal. I’d have to think Miller would require at least one such player, such as Zyhir Hope, Josue De Paula, or Dalton Rushing of the Dodgers or George Lombard Jr. of the Yankees. It’s been eight years since a team parted with a top ten prospect at the deadline; Padres President of Baseball Operations & General Manager A.J. Preller holds one such chip in #5-ranked Leo De Vries. It’s also possible that contenders could win the bidding by including valuable players off the big league roster. The Padres have one of those in play in rental starter Dylan Cease; it might require a third team and a lot of creativity (and more players) to spin him into Miller. We’ll find out in less than 17 hours.
A potential Miller trade would take place in a time of uncertainty for the Athletics, who are playing in a minor league ballpark in Sacramento in the first of what is meant to be three seasons. A’s owner John Fisher held a symbolic groundbreaking for his new Las Vegas stadium back in June, though it’s still unclear how that will be financed.
Padres Interested In Mason Miller, Continuing To Pursue Jarren Duran
The Padres continue to lurk on some of the top potential trade candidates. Jen McCaffrey of The Athletic wrote this afternoon that San Diego remains enamored with Red Sox left fielder Jarren Duran. Dennis Lin and Ken Rosenthal at The Athletic write that the Friars are involved on Guardians left fielder Steven Kwan as well. Lin and Rosenthal also report that the Padres have interest in A’s flamethrower Mason Miller.
Miller remains a long shot trade candidate but would be one of the most impactful arms available if the A’s seriously consider dealing him. Rosenthal reported this afternoon that the Phillies, Mets and Yankees had all been in touch with the A’s. The Phils and Mets were evidently deterred by the asking price. Philadelphia went on to acquire Jhoan Duran, while the Mets added Ryan Helsley. The Yankees have not pivoted to a different late-game weapon. However, SNY’s Andy Martino suggested this evening that the A’s asking price was high enough that talks with the Yanks had yet to become especially serious.
The Padres have two prospects on Baseball America’s most recent Top 100 update: infielder Leo De Vries at #5 and catcher Ethan Salas at #65. They’d previously been reluctant to part with either player. Salas’ stock has dipped in recent months, largely because of a back injury that has kept him on the minor league injured list since late April. Salas is still a very good prospect, but De Vries is the clear top talent in the system.
San Diego could have a tough time acquiring an impact player with multiple years of control unless they’re willing to put De Vries on the table. Rosenthal and Lin write that the Padres are at least willing to discuss De Vries and Salas in trade conversations. It stands to reason they’d prefer to build a package around the latter, but his injury might make that difficult right now.
MassLive’s Sean McAdam suggested last week that the Red Sox rebuffed a framework built around Salas and Dylan Cease in talks on Jarren Duran. McCaffrey suggested today that Boston would be more open to building a Duran package around Cease and De Vries. That might be a bridge too far for San Diego.
The Padres’ interest in Miller comes as the Friars are simultaneously considering trading away MLB pitching. They’ve been open to offers on Cease for a few days, listening on the impending free agent starter while separately acquiring controllable pitching. There’d be a similar logic in shopping closer Robert Suarez, who may opt out of the remaining two years and $16MM on his contract. Jon Heyman of The New York Post relayed this morning that Suarez is indeed in play in talks with other clubs. (As impending free agents, neither Cease nor Suarez would be of any interest to the A’s.)
San Diego could try to arrange a Suarez deal while making a push for Miller to replace him in the ninth inning. Rosenthal and Lin also float the possibility of the Padres stretching Miller back out as a starting pitcher. That’d be a very difficult ask midseason but could be more viable next spring. Miller moved to the bullpen because of a concerning injury history that included shoulder and elbow issues. Throwing as hard as he does puts plenty of stress on a pitcher’s arm. Still, the upside of returning Miller to a rotation role would be tantalizing. The Padres have had success with Seth Lugo, Michael King and (to a much lesser extent) Stephen Kolek as reliever to rotation conversions. Cease and King are impending free agents, and there’s not much in the way of controllable starting pitching to go around.
None of this is to say that San Diego making a blockbuster acquisition is likely. The A’s control Miller for four and a half seasons. They’re not going to trade him for anything less than a monster haul. It’d take a bigger return than what the Phillies sent to Minnesota for two and a half years of control over Jhoan Duran: top 100 catching prospect Eduardo Tait and young starter Mick Abel. That’s probably also true for Jarren Duran and Kwan, All-Star caliber outfielders who are controllable for multiple seasons. A lot could hinge on De Vries, but if the Padres are genuinely willing to consider dealing one of the 10 or so best prospects in the sport, that’d open plenty of opportunities for a huge swing.
Yankees, Mets, Phillies Have Discussed Mason Miller With A’s
The Yankees, Mets, and Phillies have all engaged in talks with the Athletics regarding closer Mason Miller, reports The Athletic’s Ken Rosenthal. This update comes 10 days after USA Today’s Bob Nightengale reported in no uncertain terms that Miller was off the market. While Rosenthal does not suggest a trade is likely, it seems the A’s are at least entertaining offers.
Any conversations between the A’s and Phillies may have been brief. Rosenthal notes the A’s asked for Philadelphia’s top pitching prospect, Andrew Painter, in return for Miller. But as Rosenthal and colleague Matt Gelb reported earlier today, the Phillies “refuse to even entertain the thought of moving Painter.” Rosenthal and Gelb suggested that the Phillies’ refusal to part with Painter likely eliminates them from the market for Miller or Twins closer Jhoan Duran.
Rosenthal also throws a bit of cold water on the Yankees connection. The A’s, he explains, are seeking top-tier young arms (hence their interest in Painter). Meanwhile, he mentions that the Yankees are “more focused on adding pitching than subtracting it.” In other words, the A’s are presumably seeking close-to-MLB-ready pitchers (as their interest in Painter implies), and the Yankees, who have learned a lot about the value of pitching depth this season, might not be willing to part with the sort of players who meet the Athletics’ criteria.
As for the Mets, they might not be quite as interested in Miller after they dealt for Tyler Rogers this afternoon. Rogers might not have Miller’s closing experience, high ceiling, or years of team control, but he’s arguably having a better season than Miller, and he and Edwin Díaz give the Mets a strong one-two pairing of right-handers at the back end of their bullpen. The Mets also traded for left-hander Gregory Soto last week, so they might now prefer to focus their efforts on improvements in other areas.
All this to say, the chances of Miller being moved this summer still seem slim, but it might not be out of the question. Perhaps if fellow closers Duran or Ryan Helsley fetch a high enough price for the Twins and Cardinals, respectively, the Athletics will be convinced to take advantage of a relatively weak trade market and the high number of contenders seeking bullpen help.

A’s Rebuffing Trade Interest In Mason Miller
The Athletics are lined up to be sellers at the deadline, but their July 31 moves won’t extend to a certain long-term closer. Mason Miller appears to be more or less untouchable, as USA Today’s Bob Nightengale writes that the A’s are telling interested teams that the reliever isn’t available in trade talks.
While things could conceivably change if a particular club makes an outsized offer, it makes sense that the A’s have no interest in moving Miller, who is under team control through the 2029 season. The right-hander has yet to even reach salary arbitration, though he’ll hit that milestone a year early since Miller is on pace to easily qualify for Super Two status. This means he’ll gain four years of arbitration eligibility instead of the usual three.
Since traditional counting statistics are weighed more heavily in arbitration cases than more advanced analytics, a closer who racks up big save totals can put himself in line for some increasingly hefty paydays through the arb process. As such, Miller stands to cash in given that that he already posted 47 saves (out of 53 chances) over his three MLB seasons. While this rising price tag might make the Athletics more open to dealing Miller at some point during his arbitration years, there isn’t any urgency for the A’s to make a move just yet, even if he has been whispered in trade speculation for over a year.
[Related: Athletics Trade Deadline Outlook, for MLBTR Front Office subscribers]
After making his big league debut in 2023, Miller was installed as the Athletics’ closer at the start of the 2024 campaign and he essentially hasn’t looked back. The righty has a 3.22 ERA and a stunning 37.5% strikeout rate over 134 career innings, with an average fastball velocity of 100.2mph. That high-octane fastball is paired with an 87.2mph slider that has been one of the more effective pitchers in baseball over the last two seasons. Control is a question mark, as Miller’s below-average walk rate in 2024 has sunk to a troubling 12% in 2025.
Between this control issue and the general volatility of relief pitching, an argument can be made that the A’s would be well served to sell high on Miller while he is at peak trade value. Miller dealt with some early-career injuries that necessitated his move from starting pitching to the bullpen in the first place, so this health history is another reason the front office could reasonably consider a trade at some point.
On the flip side, the Athletics have shown indications that they’re ready to end their rebuild, even if their results in 2025 have been disappointing. The club locked up Lawrence Butler and Brent Rooker to long-term extensions this past spring, and signed Luis Severino to a team-record $67MM free agent deal this past offseason. This counts as a massive spending splurge by the Athletics’ traditionally low-spending standards, though it appears as though their extension discussions didn’t extend to Miller, who said in mid-March that the club had yet to broach the subject of a long-term extension. Some sort of multi-year agreement might be a wise move for the A’s to gain some cost certainty through Miller’s arbitration years, even if the club might be hesitate about a commitment beyond the 2029 campaign.
No Extension Talks Thus Far Between A’s, Mason Miller
The A’s have handed out two of the largest extensions in franchise history in recent months. They inked DH Brent Rooker to a five-year, $60MM guarantee in January. Earlier this week, they finalized a seven-year deal with outfielder Lawrence Butler that guarantees $65.5MM.
It’s possible that the Butler deal is the first of multiple A’s extensions in Spring Training. General manager David Forst told Evan Drellich of The Athletic a couple weeks ago that the team had opened talks with a few players. With Butler signed, closer Mason Miller should arguably be the team’s top extension candidate.
Miller told Foul Territory’s A.J. Pierzynski on Friday afternoon that he’s open to talks but hasn’t heard from the team about the possibility. The A’s control the hard-throwing reliever for another five seasons. Miller will qualify for early arbitration as a Super Two player next winter. He’d go through that process four times unless he signs an extension.
The A’s may not be eager to commit to a reliever, even one as dominant as Miller, whom they already have under control for a half-decade. There’s downside associated with the general volatility of relief pitching. Miller’s stuff is so exceptional that he’s a safer bet than almost any reliever to remain effective, but there’s more of a risk from a health perspective. He battled shoulder and elbow injuries and pitched fewer than 40 innings in the minor leagues.
[Related Front Office Post: Who Else Could The A’s Look To Extend?]
Forearm tightness wiped out most of his ’23 season and was the main reason the A’s moved him out of the rotation during the 2023-24 offseason. Miller stayed healthy last year aside from an incident where he fractured the pinkie on his left (non-throwing) hand, which reportedly occurred when he hit a training table in frustration after a poor outing. That’s presumably not a concern moving forward, but as baseball’s hardest thrower, he certainly puts a lot of stress on his elbow and shoulder.
There have been a handful of extensions for relief pitchers in the 1-2 year service bucket. Miller would almost certainly look to set a new standard for that class if the A’s were interested in an extension. Emmanuel Clase’s five-year, $20MM guarantee is the current record. That deal, which was signed in April 2022, included a pair of $10MM club options to extend Cleveland’s control window by two seasons. Clase was coming off an outstanding first full season, turning in a 1.29 ERA with 24 saves and 74 strikeouts in 69 2/3 innings. Miller struck out 104 hitters with a 2.49 earned run average over 65 frames last season. He went 28-31 in save chances.
Clase’s deal is a three-year old precedent that has turned into an extremely team-friendly contract. Clase also wasn’t on track to reach Super Two status, which meant he was two years from arbitration and had a much lower earning power through that process. Arbitration salaries escalate annually, and Super Two qualification sets a higher baseline for future raises. Clase didn’t have Miller’s injury history, but the Cleveland closer had served a performance-enhancing drug suspension in 2020 that added a different risk to his profile.
A’s Looking To Add Third Baseman, “Wouldn’t Rule Out” Another SP Addition
7:26pm: The A’s inquired after Bohm with the Phillies, according to a report from The Athletic’s Ken Rosenthal, but Philadelphia’s request for star closer Mason Miller in return for Bohm’s services reportedly ended those discussions.
5:49pm: As the Athletics gear up to play the 2025 campaign in their temporary home of West Sacramento while waiting on a more permanent move to Las Vegas, they’ve made an effort to put a more competitive product on the field after showing signs of progress with a 32-32 record after the All-Star break during their final season in Oakland. Those efforts to bolster the roster started when they inked right-hander Luis Severino to a three-year deal and continued today when they landed left-hander Jeffrey Springs in a five-player trade with the Rays earlier today.
The addition of Severino and Springs to the top of the A’s rotation adds some credibility to the club entering 2025 after the club’s starters struggled to a 4.76 ERA that was a bottom five figure in the majors last year. Severino and Springs will front a rotation that currently also figures to feature JP Sears, Mitch Spence, and Joey Estes on Opening Day, but club GM David Forst indicated to reporters (including Martin Gallegos of MLB.com) that he “wouldn’t rule out” adding another starter to the mix. In addition to continuing to weigh a potential third rotation addition, Forst suggested (as relayed by Gallegos) that he intends to explore both the trade and free agent markets for a potential third base addition.
The A’s significant additions and newfound willingness to commit to a higher payroll come with off-the-field concerns attached in addition to desire to improve the roster on the field. Reporting earlier this week indicated that the A’s would run the risk of a grievance from the MLB Players Association if they don’t spend 150% of their revenue sharing money on MLB payroll. With the A’s reportedly expected to rake in $70MM or more in revenue sharing, that means they’ll need a payroll of $105MM or more for luxury tax purposes in order to avoid risking a grievance from the players’ union. After today’s trade to land Springs, RosterResource projects the club for an $88.5MM luxury tax payroll in 2025. That still leaves around $15MM in budget room for luxury tax purposes before they reach that $105MM benchmark, which ought to leave the door open for the club to another addition or two.
In the rotation, even a back-of-the-rotation veteran such as Andrew Heaney or Kyle Gibson (who the A’s were previously connected to prior to the Springs deal). would likely eat up most if not all of that $15MM. It’s at least theoretically possible the club could look to spend beyond that, however. Previous indications have suggested that the club was targeting a payroll in the $100MM range for 2025. Given that RosterResource’s projection for the club actual payroll in 2025 in terms of cash paid out is just over $64MM, that would leave substantially more room to spend than if the A’s are targeting a payroll in the $100MM range for luxury tax purposes. That could make both the addition of a back-end starter and a notable salary at third base feasible.
Turning to the hot corner, the position has been the focus of a number of different clubs in the rumor mill this winter. The Cubs dealt third baseman Isaac Paredes to the Astros just yesterday, and Houston’s longtime third baseman Alex Bregman remains one of the most coveted players on the free agent market. Meanwhile, the Cardinals have made clear their intentions of dealing Nolan Arenado this winter. The Angels, Tigers, Yankees, and Astros are among the other teams known to be in the market for third base help, while the Red Sox and Padres remain on the periphery of the market as teams with established third basemen who have been connected to potential third base options like Bregman and Arenado as solutions at other positions.
It’s nearly impossible to imagine a top-tier free agent like Bregman or a veteran with no-trade protection such as Arenado choosing to play out a long-term deal in West Sacramento, but that doesn’t mean the A’s are completely out of luck if they hope to add a third baseman to their roster this winter. Alec Bohm of the Phillies is one frequently-discussed trade candidate at the hot corner, and Diamondbacks veteran Eugenio Suarez has seen his name percolate in the rumor mill as another possible trade chip. Meanwhile, Jorge Polanco, Paul DeJong, and Yoan Moncada are among the potential third base options available in the lower tiers of the free agent market, and it’s possible that a club with an infield surplus such as the Blue Jays or Orioles could make someone like Davis Schneider or Ramon Urias available in trade.
A’s Not Discussing Rotation Move For Mason Miller
Last offseason, the Athletics moved Mason Miller from the rotation to the closing job. General manager David Forst said at the time that the A’s were open to building the right-hander back up as a starter after one season in relief. That doesn’t seem to be on the table for now.
“We’re not talking about moving him back into a starting role,” Forst told John Shea of the San Francisco Chronicle this week. While that doesn’t preclude having the conversation at some point during the offseason, it appears the likelier outcome is that Miller will remain in the ninth inning.
Stretching Miller back out would be a huge risk-reward play for the A’s. A few teams have had success with converted relievers in recent seasons. Garrett Crochet immediately looked like a budding ace when the White Sox gave him a starting job. Seth Lugo and Michael King have gone from setup relievers to borderline top-of-the-rotation starters. Reynaldo López and José Soriano found success but battled injury issues in their returns to starting. Free agent righty Jeff Hoffman has drawn interest as a potential rotation conversion.
Miller is talented enough that a Crochet arc would be within the realistic range of outcomes. The A’s are concerned that a starter’s workload would weigh heavily on his arm, though. Miller has battled shoulder and elbow injuries and pitched fewer than 40 innings in the minor leagues. He started six MLB games as a rookie in 2023. Miller was pitching well but forearm tightness shelved him between mid-May and the start of September. The A’s used him out of the bullpen for the season’s final month and kept him in that capacity this year.
The 26-year-old’s first full season as a closer could hardly have gone better. Miller’s already elite velocity jumped in short stints. His fastball averaged nearly 101 MPH and routinely got into the 103-104 range. Between that kind of life and a wipeout slider, Miller was almost untouchable. He turned in a 2.49 ERA while striking out almost 42% of opposing hitters through 65 innings. Opponents swung and missed at nearly a fifth of his offerings. Among relievers with 50+ innings, only Josh Hader and Braves’ breakout lefty Dylan Lee got swinging strikes more frequently. Miller locked down 28 of 31 save attempts.
Most importantly, Miller’s arm held up. His only injury this year was a three-week absence due to a small fracture in his non-throwing hand. (He reportedly sustained that injury when he struck a training table in frustration after a poor outing.) It took all of a few weeks for Miller to establish himself as an elite late-game weapon.
Relievers aren’t immune to injury, but the A’s clearly feel better about his chances to stay healthy working in 1-2 inning stints. Assuming they don’t reverse course later in the offseason, he’ll project as one of the best closers in baseball. Other teams called on Miller at the deadline and surely will do so again this winter, but a trade would be a surprise. He’s still a year from arbitration and under club control for five seasons. The A’s are no longer aggressively tearing down the roster. They were relatively quiet at the deadline. Forst has already declared they’re keeping Brent Rooker, their best trade chip aside from Miller.
The A’s will need to add multiple starting pitchers. Their rotation is among the thinnest in the league. Players like JP Sears, Mitch Spence and Joey Estes headline the group. They all look like back-of-the-rotation arms at best. With almost nothing on the books for next season, Forst and his staff should be able to take on money via trade and/or a mid-level free agent strike to add innings.
Athletics Outright Gerardo Reyes
Aug. 9: The A’s announced that Reyes went unclaimed on waivers and has been assigned outright to Triple-A Las Vegas. He’s been outrighted in the past and thus has the option to reject the assignment in favor of free agency.
Aug. 7: The Athletics announced that they have reinstated right-hander Mason Miller from the 15-day injured list and recalled infielder Armando Alvarez from Triple-A Las Vegas. In corresponding moves, they placed outfielder/first baseman Seth Brown on the paternity list and designated righty Gerardo Reyes for assignment.
Miller has been one of the best relievers on the planet this year with a 2.21 earned run average in 40 2/3 innings. He has struck out a massive 45.8% of batters faced while keeping his walks to a reasonable 9.2% level and also getting grounders on 40.6% of balls in play. He has secured 15 saves in 17 opportunities on the year.
He’s been on the IL for a couple of weeks now due to a fractured pinkie finger in his left hand. There was some initial confusion about how the injury came about, but manager Mark Kotsay confirmed that Miller had struck a padded table in frustration, in video relayed on X by A’s on NBCS. Though it’s disappointing when injuries come about in such fashion, Miller has thankfully returned after a minimal absence. Since the injury was to his non-throwing hand, he initially wasn’t able to squeeze his glove but was able to throw while on the shelf.
While Miller was out of action, the club traded Lucas Erceg to the Royals and selected Reyes to take his spot on the roster. Reyes has since tossed four innings for the A’s, only allowing two earned runs despite issuing three walks and only punching out two opponents. It seems he wasn’t part of the club’s long-term plans and has been nudged off the 40-man roster since he’s out of options.
Since the trade deadline has passed, the A’s will place him on waivers in the coming days. He now has a 7.13 ERA in 41 2/3 major league innings but has generally been better in the minors. That includes 33 Triple-A innings prior to his call-up this year with a 3.82 ERA. His 12.1% walk rate in that time was high but he punched out 36.4% of batters faced. If any club puts in a claim, Reyes has less than a year of service time and can therefore be cheaply retained beyond the current campaign.
AL West Notes: Tucker, Miller, Mariners
Astros outfielder Kyle Tucker has been on the injured list due to a right shin contusion for nearly two months now, but it doesn’t appear as though he’s likely to join the club’s lineup anytime soon as they attempt to pull away from the Mariners in a tight race for the AL West crown. As manager Joe Espada told reporters (including Matt Kawahara of the Houston Chronicle) earlier today, the club is not yet certain if Tucker will be able to contribute in the majors at any point in the month of August. Espada described the situation with Tucker as a day-to-day situation, adding that while it’s a “possibility” he could play at some point this month it would be “too aggressive” for him to commit to that timeline.
It’s a frustrating update for Astros fans, as Tucker had been without a doubt the club’s best hitter prior to the injury. In 262 trips to the plate across 60 games this year, the 27-year-old was slashing an otherworldly .266/.395/.584 (172 wRC+) that made him one of the top bats in the entire sport at the time of his injury. In his absence, the Astros have turned their season around in a big way with a 32-19 record since the start of June thanks in large part to strong offensive performances from previously-struggling players like Yainer Diaz and Alex Bregman. With more of the Houston lineup contributing on a daily basis in recent weeks, it’s easy to imagine the return of Tucker providing the lineup with an additional spark that could help buoy the club as they pursue their eighth consecutive appearance in the ALCS. Of course, even a return sometime in September could give the young star plenty of time to prepare for a potential playoff run while still meaningfully contributing to games down the stretch.
More from around the AL West:
- The Athletics offered a positive update regarding injured closer Mason Miller today, as relayed by MLB.com’s Martín Gallegos. According to Gallegos, Miller played catch without his cast today as he rehabs from a fractured finger in his non-throwing hand. The next step for the righty is to throw a live bullpen session in a simulated game on Monday. The 25-year-old phenom has become one of league’s best-known relievers this year by dominating to a 2.21 ERA with a 1.72 FIP in 40 2/3 innings of work as Oakland’s closer, a role that’s seen him rack up 15 saves. Miller last pitched on July 22 and was placed on the IL a few days later after fracturing his left pinkie finger in the club’s training room. If that bullpen session goes well, it seems possible that the righty might be able to skip a rehab assignment entirely and return not long after he’s first eligible to come off the shelf on August 7.
- Mariners fans received some unfortunate news from down on the farm recently as Ryan Divish of The Seattle Times reports that shortstop Felnin Celesten underwent season-ending surgery to repair a preexisting hamate injury. Celesten, 18, is the club’s #5 prospect according to MLB Pipeline and was among the top prospects of the 2023 class of international amateurs. Signed out of the Dominican Republic to a $4.7MM bonus, Celesten is considered a high-floor prospect with a strong defensive reputation at shortstop and solid all-around tools. In his first taste of stateside ball this year, Celesten slashed an excellent .352/.431/.568 in 32 Arizona Complex League games before being sidelined by injury. It seems likely he’ll get his first taste of full-season ball sometimes next year once he’s returned from rehab.
A’s Place Mason Miller On Injured List With Broken Left Hand
3:10pm: Gallegos now tweets that Miller “did not pound the table out of frustration” but rather “put his hand down awkwardly” while getting ready to do an exercise.
3:02pm: The A’s indeed announced that Miller has been placed on the 15-day IL due to a fractured left hand. He’s the corresponding move to activate right-hander Ross Stripling from the 15-day IL.
2:47pm: The Athletics are placing star closer Mason Miller on the 15-day injured list due to a fractured pinkie finger in his left (non-throwing) hand, reports Martin Gallegos of MLB.com. Miller suffered the injury when he pounded a padded table in the Athletics’ training room out of frustration earlier this week, per Gallegos.
Miller has been one of the most oft-speculated names on the trade market throughout the season. The A’s were considered long shots to trade the right-hander anyhow, given that they control him for five additional seasons. ESPN’s Buster Olney reported earlier this week that Miller was “out of play” on the trade market. Whether that was due to this injury — Olney’s report came yesterday, while Miller’s injury occurred Monday, per Gallegos — or whether the A’s had simply decided the offers weren’t going to be sufficient isn’t clear.
Regardless, it now seems quite likely that Miller will remain with the A’s through the deadline. A trade is still technically possible, but it was already going to be difficult to line up on valuing five years of control over perhaps MLB’s most dominant reliever. Throwing an injury into the mix only further complicates the scenario and makes it more difficult for the A’s to extract max value.
The 6’5″ Miller is a flamethrowing powerhouse who’s averaged 100.9 mph on his heater this season, per Statcast, and fanned a comical 45.8% of his opponents. This year’s 9.2% walk rate is a step forward from last year’s 11.5% mark. Opponents rarely make contact against Miller in the first place, and when they do, it’s typically feeble in nature. He’s yielded just an 86.6 mph average exit velocity and a putrid 29% hard-hit rate on the season. Only four of the batted balls against Miller have been “barreled” as measured by Statcast. Miller’s gargantuan 20.3% swinging-strike rate leads all pitchers in MLB (min. 10 innings pitched). He’s sitting on a 2.21 ERA with even better marks from metrics like FIP (1.68) and SIERA (1.62).
Miller entered the season with under one year of major league service time. He’s under club control for another five seasons beyond the current campaign, though he’ll finish the 2025 season with 2.166 years of service time, making him a surefire Super Two player. That’ll let him go through the arbitration process four times rather than the standard three. Either way, he can’t become a free agent until the 2029-30 offseason.
Miller’s utter dominance and that mountain of club control made him one of the most coveted players on the trade market, although it bears repeating that a deal was in no way a strong likelihood.
