2026 Fantasy Outlook
The Padres once again made the biggest splash on the relief market at the 2025 trade deadline, acquiring Miller from the Athletics. The 27-year-old brought closing experience with him to San Diego, but he recorded only two of the team's 13 saves over the final two months of the season with Robert Suarez anchoring the club in that role. With Suarez recently opting out of his contract to become a free-agent, Miller is the natural choice to slide into San Diego's closer role. However, the Padres aren't ruling out giving him an opportunity to start, particularly if they lose both Dylan Cease and Michael King in free agency. Miller has been a full-time reliever the last two seasons and has been arguably the best bullpen arm in the game during that span, collecting a 2.56 ERA, 0.89 WHIP and 43.1 percent strikeout rate over 126.2 innings. Last year, his slider limited opposing hitters to a league-best .108 BAA and 54.6 percent whiff rate for that pitch type. Read Past Outlooks
Signed a one-year, $4 million contract with the Padres in January of 2026.
Named closer by manager
Padres manager Craig Stammen confirmed Wednesday that Miller will serve as the team's closer in 2026, AJ Cassavell of MLB.com reports.
Analysis
The announcement was merely a formality, as Miller always appeared likely to open the season as the Padres' closer once Stammen confirmed in December that the 27-year-old righty would remain in the bullpen in 2026 and after Robert Suarez bolted for Atlanta in free agency. After being acquired from the Athletics last July in a stunning deadline deal, Miller turned in a 0.77 ERA, 0.73 WHIP and 45 strikeouts to go along with two saves in 23.1 innings to close out the Padres' regular season. Now that he's in line to receive the overwhelming majority of save chances in San Diego to go along with his typically pristine ratios, Miller has a strong argument for being the first closer off the board in fantasy drafts.

Past Fantasy Outlooks
2025
2024
2023
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.

Latest Fantasy Rumors
Trade talks didn't progress
The Mets wanted to acquire Miller from the Padres via trade but talks between both clubs "went nowhere," according to Jon Heyman of The New York Post.
Analysis
That outcome shouldn't be a surprise, as the Padres paid a steep price to acquire Miller from the Athletics only a few months ago. Even though the Padres have been fielding trade offers for Miller and other star relievers, he's not likely to leave San Diego via trade any time soon. Miller had an impressive finish to the 2025 campaign after being traded to San Diego with a 0.77 ERA and 45 strikeouts across 23.1 regular-season innings.
