2025 Fantasy Outlook
Giolito's first season with Boston ended before it began when he suffered an elbow injury in spring training that required surgery. Doctors opted for an internal bracing procedure, which gave Giolito a chance for a normal offseason. He began throwing in August and was in Fort Myers on a throwing program during the offseason. There could be restrictions early on, but Giolito is expected to be at spring training with other pitchers. He received Cy Young votes every season from 2019 to 2021, but his career arc took a hit in 2023 when he gave up 41 home runs with a 41.9 percent hard-hit rate. He said the troubles were due to falling behind batters and missing location in the zone. Thought of as a front-end starter after signing with Boston, it's a good bet that the organization isn't counting on a top-of-the-rotation starter in 2025, but the 30-year-old should have a spot at the back end.

Fully recovered from elbow injury
Giolito said Saturday in an appearance on Audacy's "Baseball Isn't Boring" podcast that he began his offseason throwing program in mid-October and is fully recovered from the right elbow injury that ended his season in late September.
ANALYSIS
The right-hander came down with right elbow soreness at the end of the regular season and was unavailable to pitch in the playoffs for the Red Sox. However, Giolito noted that "within three days, my elbow felt 100 percent fine again," and "whatever injury there was, it's gone." Giolito is entering free agency, and assuming his medicals check out fine, he should receive plenty of interest on the open market. The 31-year-old held a 3.41 ERA and 121:56 K:BB over 145 innings for Boston in 2025.

In 2022, Giolito registered a 4.90 ERA but a 3.66 xFIP and 3.79 SIERA portended a rebound last season. Things did not turn out as hoped for as Giolito recorded a 4.88 ERA pitching for three different teams. This time, the bloated ERA was mostly supported by its estimators as the righty's control and command suffered all season. Fanning 204 in 184.1 innings was solid, but a 9.2 percent walk rate and 41 homers surrendered were major reasons the White Sox and Angels gave up on Giolito before the pitching desperate Guardians picked him up to absorb innings down the stretch. Giolito's velocity and pitch mix was in sync with recent seasons, and after signing a two-year deal (with an opt-out after the first year) with Boston, there's hope that new pitching coach Andrew Bailey can help Giolito maximize a sweeper and return to the form he showed in the first half last year with Chicago (3.45 ERA). Giolito misses bats and hasn't missed more than a start or two every season since 2018, although he'll now be pitching in his most hitter-friendly home park to date.
