Padres Trade Rumors: Mason Miller a Prime Target as Deadline Looms
Miller, 22, made his MLB debut in 2023 and was an All‑Star in 2024 and 2026. He has posted a 0.79 earned‑run average (ERA) this season, a 49.4 % strikeout rate, a 46.5 % ground‑ball rate, and an 8.7 % walk rate. He is earning $4 million this year and is under team control for three more seasons through arbitration. The Padres’ bullpen is one of the strongest in the league, ranking seventh in ERA with a 3.70 ERA, a 1.274 WHIP, and 32 saves. The bullpen’s save percentage is 69.6 %.
The Padres’ farm system has been a point of concern. Baseball America’s most recent rankings, released before the 2026 draft, placed San Diego last in the league. FanGraphs and other outlets also rank the Padres at the bottom. The organization has traded away several prospects in recent years, including Leo De Vries, Dylan Cease, Luis Arraez, Jason Adam, Tanner Scott, Bryan Hoeing, Ramón Laureano, Ryan O’Hearn, and Freddy Fermin. The result is a roster that relies heavily on the major‑league bullpen and a rotation that is uneven.
The starting rotation is a particular weakness. Michael King is the only pitcher with an ERA under 5.00, while the rest of the rotation—Griffin Canning, Walker Buehler, JP Sears, and Germán Márquez—have ERAs above 5.00. Sears, who had a 7.92 ERA in Triple‑A before being called up, is currently the only arm with a respectable strand rate (73.1 %) and a low batting average on balls in play (.241). Joe Musgrove and Nick Pivetta are on the injured list, and it is unclear whether they will return in time to contribute. King could opt out of his contract this offseason, and Pivetta also has an opt‑out clause, though an injury provision may convert it to a $14 million club option.
Because of these roster dynamics, a trade that brings a controllable starter to the Padres would make sense. The team has previously traded for a starter in the past, most notably when it acquired Michael King in a deal that also involved Juan Soto and Trent Grisham. The Padres have also acquired Mike Clevinger in a multiplayer deal with the Cleveland Indians earlier in the season.
Trade rumors have identified several potential destinations for Miller. Teams that are currently contending and have playoff‑caliber starters to spare would be the most likely buyers. Those teams would also want to add a bullpen arm that can lock down late‑season games. The trade would need to include a package that satisfies the Padres’ need for a starter and possibly additional prospects to help rebuild the farm system.
The trade deadline is only a week away, and the Padres have gone 5‑0 with an 11‑man bullpen in recent games, according to a report from the San Diego Union‑Tribune. The team’s front office has not made a formal offer, but the rumor mill continues to circulate. Whether the Padres will move Miller or keep him for the remainder of the season remains to be seen.
In summary, the Padres are in a precarious position: a strong bullpen, a weak rotation, a low‑ranked farm system, and a trade deadline that is fast approaching. Mason Miller’s performance and contract status make him a prime target for teams looking to add a reliable closer, while the Padres would likely seek a controllable starter in return. The next few days will determine whether the Padres make a move that could shape the remainder of the 2026 season and the organization’s future.
