Drey Jameson DVOA, Advanced Stats, & Fantasy Rankings

Arizona Diamondbacks right-handed pitcher Drey Jameson (elbow) faced live hitters for the first time on Tuesday since undergoing Tommy John surgery. Jameson had the operation in September 2023 and is attempting to ramp up in time to make the Opening Day roster. Manager Torey Lovullo noted that his session was "electric." Jameson was able to strike out the second batter he faced. The 27-year-old pitched primarily out of the bullpen during the 2023 season and held a 3.32 ERA and a 1.42 WHIP. He struck out 37 batters across 40 2/3 innings. However, he did generate a strong 30.0 percent whiff rate and a 30.5 percent chase rate, suggesting he may see some positive regression in his strikeout production when he returns to action. Fantasy managers should expect Jameson to return to the bullpen if he is cleared for Opening Day.

Arizona Diamondbacks right-hander Drey Jameson (elbow), who was scheduled to throw a bullpen session at camp on Wednesday, is confident that he'll be ready to go on Opening Day. Jameson said there's "no question" he'll be ready. The 27-year-old had Tommy John surgery in September of 2023, which caused him to miss the entire 2024 season. He resumed throwing off a mound last July, so it's not all that surprising that he's ramping up even further this spring. The D-backs could bring him along slowly in spring training, but barring a setback with his right elbow, Jameson could win a spot in a low-leverage relief role for Arizona if he makes the Opening Day roster. Jameson has a upper-90s heater and wipeout slider that work well in relief. He had a 3.32 ERA, 1.43 WHIP, one save and 37 K's in 40 2/3 innings over 15 outings (three starts) for the Snakes in 2023. For now, Jameson is merely one to watch in deeper formats.

The Arizona Diamondbacks will likely look at right-hander Drey Jameson (elbow) as a reliever in his first season back from Tommy John surgery in 2025. Jameson is one of the team's top prospects, but he had Tommy John surgery in September of 2023 and will be ready to go in spring training in February. He threw only 68 2/3 innings between Triple-A Reno and the majors before having surgery in 2023 and obviously didn't pitch at all in 2024, so he'll be on a strict innings limit in his return next year. If that's the direction the Snakes go in, Jameson will lack fantasy upside in 2025, but he could still be an extremely valuable piece out of Arizona's bullpen. The 27-year-old made 15 big-league appearances (three starts) for the D-backs in 2023 and had a 3.32 ERA, a 1.43 WHIP, one save, 37 strikeouts and 18 walks in 40 2/3 innings.
