2025 Fantasy Outlook
Miller made six starts in 2023, but durability issues raised questions about his role entering the 2024 campaign. However, an outstanding spring of one-inning appearances carved a logical path for the 25-year-old to become the Athletics closer. The right-hander tallied the A's first save of the season and never looked back, averaging 100.9 mph on his 4-seamer while blowing away opposing hitters at a league-leading 41.8 percent clip. Miller also led qualified relievers with a remarkable 33.3 K-BB percentage. Perhaps most importantly, the hurler remained healthy for the most part, only missing a few weeks on the IL with a fractured pinkie on his non-throwing hand. The injury risk remains, but Athletics general manager David Forst recently indicated that the team is not considering moving Miller back into a starting role. His upside warrants a pick as a top-7 closer for 2025 drafts. Read Past Outlooks
Signed a one-year contract with the Athletics in March of 2025. Traded to the Padres in July of 2025.
Gets first save as Padre
Miller earned a save against the Diamondbacks on Wednesday, striking out three batters and walking one over one hitless and scoreless inning.
Analysis
The Padres rallied for two runs in the top of the ninth frame to take their first lead, and Miller got the call to protect a one-run lead in the bottom of the inning. He issued a two-out walk but overpowered the other three batters he faced, striking them out on a combined nine pitches. Miller's first two outings with the Padres weren't great -- he allowed two runs on three hits over two frames -- but his dominance Wednesday emphasizes what a tremendous impact he could make on the team's already great bullpen. That said, Miller's fantasy value actually took a hit with his move to San Diego, as he probably isn't going to be the full-time closer given the presence of All-Star Robert Suarez. Though Miller closed Wednesday, that may have been at least partly due to Suarez tossing 1.2 frames one day earlier.

Past Fantasy Outlooks
2024
2023
The three most fantasy-relevant aspects of Miller's profile are his off-the-charts injury risk, his truly elite stuff and his team context: great home park, horrific run support. Of pitchers who will enter spring training healthy, it would be hard to find anyone more likely to get injured during spring training than Miller. A shoulder injury limited him to 30.2 innings (including the Arizona Fall League) as a 23-year-old in 2022 - his first full pro season. A UCL sprain limited him to 52.2 innings in 2023, and he has only topped 60 innings twice dating back to college, logging 67.2 innings in 2019 and 98.2 innings in 2021, in part because of a Type 1 diabetes diagnosis. The fact he can touch 102 mph with his fastball only adds to the injury risk. He threw five-plus innings in three of his 17 appearances last year, and he didn't throw more than three innings in any of his 11 post-injury appearances. As scary as his durability track record is, his stuff is equally scary for opposing batters. In addition to his 80-grade fastball, he throws a mid-90s cutter, an upper-80s slider and a low-90s changeup. There are reports that the 25-year-old flamethrower could be used as a high-leverage reliever this year due to his durability issues, but this team is arguably the worst in baseball for pitcher wins and saves.

Latest Fantasy Rumors
Padres in aggressive pursuit
The Padres "are believed to be mounting the most aggressive pursuit" of Miller, Ken Rosenthal of The Athletic reports.
Analysis
The Blue Jays are also in the mix for Miller, per Rosenthal. Miller was not used in a save situation during Wednesday's win over the Mariners, with Athletics manager Mark Kotsay saying Miller was unavailable but not injured. That could indicate a trade agreement is close. Miller has four additional years of club control after this season, so it will take a hefty trade package to land him.
