Right-handed reliever Mark Leiter Jr. has agreed to a one-year deal with the Athletics, a source told MLB.com's Martín Gallegos on Thursday morning. The club has not confirmed the deal, which is pending a physical and worth about $3 million, according to ESPN's Jesse Rogers.

Leiter, who turns 35 on March 13, became a free agent on Nov. 21 once he was non-tendered by the Yankees . Although he was a key setup man for New York in the early portion of the 2025 season, he fell out of favor after recording a 7.30 ERA from May 31 on. Still, Leiter generated a lot of soft contact (88th percentile in barrel rate, 94th percentile in hard-hit rate), so although he finished 2025 with a 4.84 ERA over 48 1/3 innings, his expected ERA was 3.72. He also recorded a 3.55 FIP.
