2023 Fantasy Outlook
Whitlock's status last winter was sky high after his surprising major-league debut as a Rule 5 pick and there were as many speculating him as a starter as those believing he could even close. At the end of the day, he pitched nearly a 50/50 split as a starter and reliever with the latter work coming once he returned from the injured list with a hip issue in the summer. His numbers were more dominant as a reliever (.237 wOBA) than as a starter (.315 wOBA), but the hip certainly was a factor as it was bad enough require surgery to ultimately address the soreness after the season. The offseason acquisitions of both Kenley Jansen and Chris Martin should allow Boston the flexibility of pushing Whitlock back into the rotation as long as his offseason hip surgery recovery goes as well as expected. His overall numbers are helped by just how dominant he was in relief, but in two seasons of major league work, he has yet to have a pitch with below a 20% Whiff rate. Given the fact the entire Boston rotation is a health question mark, Whitlock could end up being the best of all the non-Sale options when it is all said and done. Read Past Outlooks

Earns first save

September 29, 2023
Whitlock picked up the save in Friday's 3-0 victory over the Orioles. He allowed one hit and no walks while striking out three over two scoreless innings.
ANALYSIS
Whitlock notched his first save of 2023 and the ninth of his career. The 27-year-old righty has been solid in relief this month with a 2.89 ERA, 0.86 ERA and 10:2 K:BB over 9.1 September innings. The 33-pitch effort likely ends a tough season for Whitlock in which he's thrown 71.2 innings with a 5.15 ERA, 1.33 WHIP and 72:13 K:BB.

Past Fantasy Outlooks
2022
2021
Whitlock, the fourth pick of the Rule 5 draft, made the Red Sox roster out of spring training and played an unexpected but important role in 2021. The former Yankees prospect pitched multiple innings in 31 of his 46 appearances, often in high-leverage. The rookie went 8-4 with 15 holds and two saves and posted a fantastic 1.96 ERA and 1.10 WHIP over 73.1 innings. The 25-year-old relies on a four-pitch arsenal of a sinker, slider, changeup and fastball. He struggles against left-handed hitters (.293 BAA), but posted a solid 27.2% strikeout rate, 5.7% walk rate and 49.7% groundball rate. Whitlock's ability to go multiple innings could lead to a bigger role in Boston's starting rotation, or he could maintain to a similar multi-inning relief role. Some ratio regression is expected either way, but if Whitlock returns to the bullpen you can count on some wins, holds and potentially saves.
This player will receive an outlook for the 2021 fantasy baseball season.
