Padres Checking In On Availability of A's Closer Mason Miller

Dennis Lin and Ken Rosenthal of The Athletic have reported that the Padres are kicking the tires on Athletics' closer Mason Miller. They're also still pursuing Red Sox outfielder Jarren Duran, but we've covered that elsewhere.

The 26-year-old right-handed Miller owns the game’s top average four-seam velocity at 101.2 mph and has converted 20 saves in 38 outings. Through July 30, he has worked 38 1/3 innings with a 3.76 ERA, a 2.86 FIP, and a 39.1 percent strikeout rate, while holding opponents to a .246 batting average on balls in play. Miller still earns the league minimum $765,000 and is under club control through 2029, an attractive fit for a Padres payroll that has little wiggle room.

Oakland’s price is correspondingly high. Sources say the president of baseball operations, A.J. Preller, is willing to discuss either of his premier prospects—shortstop Leo De Vries or catcher Ethan Salas—to obtain Miller or controllable outfielders Jarren Duran and Steven Kwan. De Vries, 19, is thriving at High-A and is the Padres' top prospect, while Salas remains sidelined by a lower-back stress reaction but is still a teenager.

Despite having one of the better bullpens in baseball, San Diego is weighing changes. Closer Robert Suarez carries a 3.50 ERA and a 3.28 FIP over 43 2/3 innings, but he can opt out of the two years and $20 million left on his deal after the season, making him a potential trade chip. Miller started six games as a rookie in 2023; the Padres have recently transitioned former relievers Michael King, Seth Lugo, and Stephen Kolek into starting roles, so that background could add further appeal if a deal is reached.
