2025 Fantasy Outlook
A strong spring earned Whitlock a spot in the Red Sox's Opening Day rotation in 2024. He made four starts, leaving the last with an oblique injury. While on rehab, he experienced soreness in his right elbow and was soon diagnosed with an injured right UCL. Whitlock avoided Tommy John surgery, instead undergoing the internal brace procedure that entails a still lengthy, but shorter, rehab than Tommy John. He began throwing in the fall but may not be ready for opening day. His role is up in the air and may depend on the constitution of the Red Sox staff at the time. The club is likely to choose a path in the spring. It could take longer to stretch out for a starting role. Whitlock has demonstrated the ability to be effective in any role, though there's always uncertainty returning from major surgery. His role and effectiveness are unclear, but he's worth a speculative pick, especially in leagues with a fantasy IL, or the ability to cut bait if needed. Read Past Outlooks

Makes spring debut
Whitlock allowed an unearned run on one hit and struck out one over one inning in Friday's spring game against the Marlins.
ANALYSIS
Whitlock made his Grapefruit League debut Friday and worked the fourth inning when Miami's regulars were still in the lineup. He's spent the last 10 months recovering from an internal brace procedure, but Boston manager Alex Cora still sees Whitlock as a high-leverage reliever that can throw multiple innings.

The American League waiver wire is packed with options as Opening Day approaches, and the return of Nolan Jones to the Cleveland Guardians should settle their murky right field situation.

Several job battles have been settled around the American League, including the Royals' fifth starter job, which appears to have been won by Kris Bubic.

Brad Johnson completes his pitching staff wrap up with the New York Yankees, who could be one of the best staffs this season with the addition of Max Fried.
Past Fantasy Outlooks

2022
2021
Whitlock had a delayed start last season after undergoing hip surgery in 2022, but made his debut in early April. The 27-year-old right-hander opened 2023 in Boston's starting rotation and had mixed results, alternating good starts with bad ones. Combining this inconsistency with a couple of trips to the injured list - both for right elbow issues - was enough to dim Whitlock's fantasy light last season. After missing about three months total, Whitlock returned to the mound in August, this time as a multi-inning reliever. However, he couldn't quite get the handle of his changeup (.312 BA, .559 SLG), which has been a reliable offering since his rookie season. On the plus side, Whitlock struck out 25 over his final 20 innings and still possesses some upside if the Red Sox can ever settle on his role. At this point it's unclear which direction Boston plans to go, but keeping him as a reliever would make sense given he's topped 90 innings just once in his professional career, which was his first full season back in 2018.

Latest Fantasy Rumors

Will move into starting rotation
Whitlock, who finished the 2022 season dealing with a hip injury, was told that he will almost certainly be a starter in 2023, Chris Cotillo of The Springfield Republican reports.
ANALYSIS
Whitlock made 31 appearances for the Red Sox in 2022, with nine of them coming as a starter. His reputation as one of the best arms in Boston's bullpen -- he has a 2.73 ERA and 1.06 WHIP in his career -- combined with his ability to pitch multiple innings makes him fit to be a rotation candidate.
