Booser struck out one in a clean eighth inning to record a hold Wednesday against the Athletics.
With Garrett Cleavinger (forearm) sidelined, Booser continues to serve as the top left-handed setup man in the Tampa Bay bullpen. He's given up just four earned runs in 16.2 innings since the start of August. Booser has a career-best 2.13 ERA, 0.79 WHIP and 42:6 K:BB over 38 innings for the Rays in 2026.

Booser picked up a hold Sunday against Seattle, allowing one hit and no walks in a scoreless seventh inning. He struck out two.
After struggling to a 5.52 ERA in 31 innings for the White Sox in 2025, the 34-year-old left-hander continues to serve as a legitimate weapon out of Tampa Bay's bullpen this season. Booser has a 2.08 ERA, 0.77 WHIP and 33:5 K:BB over 26 frames while logging seven holds.

Booser picked up a hold Friday against Arizona, recording the final out of the sixth inning.
After beginning the season with Triple-A Durham, Booser has since carved out a key spot in the Rays' bullpen. Through 9.1 innings thus far, the 34-year-old left-hander has a 0.96 ERA, 0.96 WHIP and 10:3 K:BB with two holds.

The Rays recalled Booser from Triple-A Durham on Sunday.
Booser was added to the Rays' 40-man roster at the end of spring training after he had attended camp as a non-roster invitee, but he remained in the minors for the first two-plus months of the season. The 34-year-old southpaw is likely to work in middle relief for Tampa Bay after accruing a 1.80 ERA, 0.95 WHIP and 24:5 K:BB across 20 innings in 23 appearances for Durham.

The Rays selected Booser's contract from Triple-A Durham on Wednesday and optioned him to Durham.
Presumably, Booser had an opt-out in his minor-league contract, and the Rays added him to their 40-man roster to prevent the reliever from exercising that clause. Booser holds a 4.28 ERA and 78:35 K:BB over 73.2 innings at the big-league level.

The Rays informed Booser on Saturday that he won't be included on the team's Opening Day roster, Marc Topkin of the Tampa Bay Times reports.
Booser gave up just one earned run and struck out nine batters over nine innings in the Grapefruit League, but despite his best efforts, he won't break camp with the big-league club. It's unknown whether he will opt to enter free agency or stick with the organization, but a decision is expected to come within the next few days.
