The Padres and A’s are in agreement on a trade sending star closer Mason Miller and left-hander JP Sears to San Diego, reports Jeff Passan of ESPN. Top prospect Leo De Vries headlines a four-player return for the A’s, Passan adds. They’ll also receive three yet-unnamed pitchers.
It’ll go down as one of the more stunning trades of the 2025 deadline. Miller is one of the sport’s most highly regarded relievers — an All-Star and fourth-place finisher in American League Rookie of the Year voting just last season. He’s controlled for another four years beyond the current season. De Vries, meanwhile, currently sits as the No. 5 prospect in the entire sport on Baseball America’s latest rankings.
It also sets the stage for a fair bit of other dealing from the Padres, who’ve been discussing current closer Robert Suarez and righty Dylan Cease in trade talks. Either or both could change hands now in trades that simultaneously net younger talent and free up payroll space for San Diego to pursue upgrades in left field, behind the plate and/or on the bench. Both Miller and Sears are still in their pre-arbitration years and thus earning just over the league minimum.
The addition of Miller strengthens what was already a powerhouse San Diego bullpen (though, as mentioned, could set the stage for a Suarez trade as well). San Diego relievers have pitched to an MLB-best 2.97 earned run average on the season and rank fifth with a collective 24.1% strikeout rate.
Miller, despite carrying a fairly pedestrian 3.76 ERA, will provide a massive upgrade. The majority of his trouble this year came in a rough month from early May to early June. He’s rattled off 14 innings of one-run ball with 18 strikeouts and four walks since June 15 and, of course, was one of the most dominant bullpen arms in the game a year ago. Miller has pitched 136 2/3 big league innings and carries a 3.16 ERA with a superlative 37.3% strikeout rate and 10.2% walk rate. He’s saved 48 games and tallied one hold in his career to date and has blown only six opportunities.
More to come.
