The Athletics recalled Basso from Triple-A Las Vegas on Monday. Basso will provide a fresh relief arm after the Athletics' bullpen was overworked in recent days. The left-hander has permitted seven runs with an 8:3 K:BB over 6.2 innings with Las Vegas in the early going this season.
The Athletics optioned Basso to Triple-A Las Vegas on Monday. Basso will head to Las Vegas to begin the season but should be near the top of the list for a promotion if the Athletics need another lefty arm out of the bullpen at any point. The 28-year-old made 11 appearances (one start) for the Athletics in 2025, accruing a 2.31 ERA, 1.80 WHIP and 8:9 K:BB over 11.2 innings.
Basso (1-1) took the loss Sunday, allowing a run on three hits and two walks over 1.1 innings against Kansas City. He recorded no strikeouts. The 27-year-old opened the game Sunday but couldn't find a rhythm, loading the bases before exiting in the second inning with one out and Tyler Ferguson later allowing an inherited runner to score. Basso didn't make his first big-league appearance of the year until Aug. 27 after dealing with a left shoulder strain and beginning with Triple-A Las Vegas. He managed strong results with a 2.31 ERA across 11 outings and 11.2 innings, though a 1.80 WHIP, 4.07 FIP and 6.9 BB/9 suggest trouble beneath the surface.
