Rest-of-Season Projections
Signed a one-year contract with the Athletics in March of 2026.
Back in Vegas
The Athletics optioned Barnett to Triple-A Las Vegas on Friday.
Analysis
After coming up from the minors Wednesday, Barnett will return to Triple-A without making an appearance for the A's in order to make room for the newly acquired Jose Suarez. The 25-year-old Barnett owns a 3.07 ERA and 1.27 WHIP over 29.1 innings at Triple-A this season and remains an option to come up later in the year for a spot start or to give the Athletics length out of the bullpen.
