Athletics selected the contract of LHP Gage Jump from Triple-A Las Vegas.
Jump will make his major-league debut on Tuesday against the division-rival Mariners with veteran Luis Severino being pushed back an extra day. The 23-year-old southpaw, who was selected in the second round of the 2024 MLB Draft out of LSU, has compiled a solid 4.50 ERA, 1.47 WHIP and 56/20 K/BB ratio across 38 innings in the hitter-friendly Pacific Coast League this season. He attacks hitters with an unorthodox delivery and a repertoire that features a mid-90s fastball, a strong curveball and multiple slider variations. Jump projects as more of a mid-rotation starter long term, but he misses enough bats to warrant immediate interest in deeper mixed leagues.
