Joe Rock

25-Year-Old PitcherRP
Tampa Bay Rays AAA
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 one-year contract with the Rays in March of 2025.
Back to Triple-A

August 1, 2025
The Rays optioned Rock to Triple-A Durham on Friday.
Analysis
Rock was summoned to the majors Thursday and allowed two hits and no walks while striking out five across three scoreless innings during the Rays' 7-4 loss to the Yankees. He'll head back to Triple-A, where he has started in 15 of 20 games and has a 4.63 ERA, 1.45 WHIP and 71:33 K:BB across 81.2 innings.
