24-Year-Old PitcherRP
Tampa Bay Rays
2025 Fantasy Outlook
The Rays were able to flip Greg Jones, a position player with no long-term future with the club, to Colorado for Rock during spring training in 2024. Rock, a 6-foot-6 lefty with back-end starter potential, logged a 4.58 ERA, 1.40 WHIP and 132 strikeouts in 139.2 innings at Triple-A in his first year with his new club, and he was added to the 40-man roster after the season. He has an unremarkable 91-93 mph fastball and an above-average slider that allows him to have success against same-handed hitters. Rock's changeup is a fringe-average offering, and he might be better deployed following an opener where he can face as few righties as possible. The Rays have plenty of starting pitching depth, and Rock is one of their less appealing options, but he could be a deep-league streamer at some point in 2025. Read Past Outlooks
Signed a $953,100 contract with the Rockies in July of 2021. Traded to the Rays in March of 2024.
Called up by Tampa Bay
PTampa Bay Rays
June 28, 2025
The Rays recalled Rock from Triple-A Durham on Saturday.
Analysis
The Rays will bring up Rock to bolster the bullpen, designating Forrest Whitley for assignment in a corresponding move. Rock has spent the entire 2025 season in Triple-A, where he has a 3-5 record in 15 games (14 starts) with a 4.81 ERA, 1.49 WHIP and 63:30 K:BB across 73 innings. He'll be available out of the Rays' bullpen and could make his major-league debut as soon as Saturday against the Orioles.
