EDGE Analysis

Giolito worked the second game of a seven-inning doubleheader for Worcester. He threw 64 pitches, with 30 of those coming in the first inning. The right-hander is expected to make at least one more rehab start before the Red Sox decide whether to activate him from the 15-day injured list, though manager Alex Cora suggested that he's leaning toward having Giolito make a fourth rehab start prior to rejoining the big-league rotation, per Chris Cotillo of MassLive.com. Giolito missed most of his first season with the Red Sox in 2024 while recovering from an internal brace surgery on his elbow, but it's a left hamstring strain that has delayed his 2025 debut.

Red Sox manager Alex Cora said Thursday that Giolito (hamstring) is "not close" to rejoining the rotation, Alex Speier of the Boston Globe reports.

EDGE Analysis

Giolito opened the season on the 15-day injured list due to a left hamstring strain that he sustained in mid-March. He wasn't shut down from throwing, and it appears he's progressed enough in his program to be closing in on a rehab assignment. There's optimism that the 30-year-old right-hander will be able to return to the Red Sox's rotation in mid-April.

The Red Sox placed Giolito (hamstring) on the 15-day injured list Thursday, Mac Cerullo of the Boston Herald reports.

EDGE Analysis

Giolito tweaked his hamstring during his first start of the spring back in mid-March. He was never shut down from throwing, and he most recently threw a two-inning simulated game at the Red Sox's spring training complex Sunday, according to MLB.com. The Red Sox appear optimistic that the right-hander won't miss much more than two or three turns through the rotation before making his team debut at some point in April.

EDGE Analysis

Giolito suffered a low-grade left hamstring strain during Tuesday's Grapefruit League start versus the Phillies. He is able to continue throwing and doesn't appear headed for a long-term absence, but with Opening Day two weeks away and just one spring inning under his belt, Giolito won't have time to be ready. The Red Sox will also be without Brayan Bello (shoulder) and Kutter Crawford (knee) to start the season, so their rotation depth will be tested. Quinn Priester and Richard Fitts both appear likely to open the season in Boston's rotation.

Giolito was diagnosed Tuesday with a low-grade left hamstring strain, Jen McCaffrey of The Athletic reports.

EDGE Analysis

Giolito suffered the injury on the first pitch he threw in his Grapefruit League debut Tuesday and was removed after completing one inning. He will be able to continue throwing, but it's uncertain if he'll be ready to make his next scheduled spring start. It's also too soon to know whether Giolito's Opening Day availability is in question, but he doesn't have much time.

Giolito (hamstring) is scheduled to undergo an MRI on Wednesday, Ian Browne of MLB.com reports.

EDGE Analysis

The 30-year-old said after departing Tuesday's spring game that he believed the hamstring tightness to be a "very minor" injury, but he's still headed for medical imaging. Giolito may not miss much time if the MRI comes back clean. Otherwise he could begin the campaign on the injured list.

Giolito believes the left hamstring injury that forced him from Tuesday's outing against the Phillies to be "very minor," Mac Cerullo of the Boston Herald reports.

EDGE Analysis

Giolito felt his hamstring tighten up on the first pitch of the game, but he remained in to complete one inning, allowing two runs on one hit and two walks. The righty has had hamstring problems in the past and said this one feels mild compared to the others, but it's not yet clear when he might be able to pitch again. Currently, Giolito is slated to make his season debut March 31 against the Orioles.
