Rays Release Forrest Whitley To Pursue NPB Opportunity

The Rays announced that they’ve released former top prospect Forrest Whitley to pursue an opportunity in Japan. Tampa Bay had selected him onto the 40-man roster a couple weeks ago to avoid losing him to minor league free agency. When the former first-round pick evidently found a better job overseas, the Rays were willing to let him depart.

Tampa Bay’s release of Whitley and trade of infielder Tristan Gray to Boston clears a couple spots on the 40-man roster. That’s down to 38 as this evening’s deadline to keep eligible prospects out of the Rule 5 draft approaches. It’s likely there are a few more cuts on the horizon for a Tampa Bay team that tends to churn the back of the roster and relies heavily on its farm system.

Whitley was once arguably the most talented pitching prospect in the sport. The Astros viewed the 6’7″ righty as a potential ace as he dominated up through the Double-A level. A failed drug test for a banned stimulant in 2018 was the first setback, and Whitley then suffered through multiple seasons ruined by injuries and underwhelming performance. That included Tommy John surgery in 2021 and a significant lat strain in ’23. Whitley could never find much of a rhythm when he was healthy enough to pitch in Triple-A.

He eventually exhausted his minor league options (even with Houston granted a fourth year) before he’d had much of a look at the big league level. He began this past season on the injured list. The Astros carried him on the MLB roster once he returned but designated him for assignment when he pitched terribly over his first 7 1/3 innings. The Rays acquired him in a cash trade but placed him on waivers after five underwhelming appearances. He cleared and finished the season as a non-roster player in Triple-A.

The final few months of the ’25 season were Whitley’s most promising in years. He fired 55 1/3 innings of 2.60 ERA ball while striking out 30.4% of opponents out of Durham’s rotation. Whitley’s heater averaged around 95 MPH and he leaned more heavily on his cutter and changeup while pulling back the usage of his sinker and curveball. It was encouraging enough for the Rays to keep him out of minor league free agency, but his out-of-options status meant he still would have needed to impress the club in Spring Training or risk heading back into DFA limbo.

Whitley is headed into his age-28 season and presumably has a rotation opportunity lined up in Japan. He has the power stuff and prospect pedigree to be one of the highest-upside NPB returnees a couple seasons from now if he carries over the form he showed in Durham. Doing so would come with a far higher earning ceiling than he was likely to find domestically. He’ll not only lock in a guaranteed contract for 2026, but he’d be able to return to MLB with the benefit of open market bidding if things go well in Japan. Whitley has yet to reach one year of MLB service time and would not have qualified for MLB free agency until his age-34 season even if he’d finally clicked at the big league level.
