Cameron Booser: Everything you need to know

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.

The Rays signed Booser to a minor-league contract Monday. Booser was non-tendered by the White Sox earlier this offseason after finishing with a 5.52 ERA, 1.52 WHIP and 35:19 K:BB over 31 innings during the 2025 campaign. The Rays will retain control of the lefty reliever through the 2030 season.
