Giolito (hamstring) will start Wednesday's game against the Blue Jays, Christopher Smith of MassLive.com reports.

EDGE Analysis

Wednesday will mark Giolito's Red Sox debut and his first start since 2023. A hamstring injury suffered during spring training has kept the 30-year-old sidelined for the first month of the season, but he's made five rehab appearances in the minors, turning in a 5.19 ERA and 1.79 WHIP across 17.1 innings between Double-A and Triple-A. He reached 85 pitches during his final outing, so he may not be under any restrictions during his first start back in the majors.

Giolito (hamstring) allowed three runs on three hits and six walks while striking out four over 4.2 innings for Triple-A Worcester on Friday.

EDGE Analysis

The six walks may jump out, but manager Alex Cora confirmed prior to the start that this would end the right-hander's time in the minors, per Henry Palattella and Brian Murphy of MLB.com. The more important number is Giolito's pitch count, which reached 85 in his fifth and final rehab outing. "He's pitching [Friday], and he should be with us in Toronto [next week]," Cora said Friday. Giolito is expected to make his season and Boston debuts Wednesday against the Blue Jays.

Red Sox manager Alex Cora said Wednesday that Giolito (hamstring) is tentatively scheduled to make his season debut May 1 in Toronto, Jen McCaffrey of The Athletic reports.

EDGE Analysis

It would be his Red Sox debut, as well, after he missed the entire 2024 season following internal brace surgery on his right elbow. A left hamstring strain is what currently has Giolito on the 15-day injured list, and he will have to come out of his fifth rehab start with Triple-A Worcester on Friday with no issues before officially being cleared to join Boston's rotation next week.

Giolito (hamstring) struck out four and allowed three earned runs on six hits and no walks over five innings in his rehab start Sunday with Double-A Portland.

EDGE Analysis

Giolito has made four rehab starts between stops with Portland and Triple-A Worcester, logging a collective 4.97 ERA, 1.74 WHIP and 13:7 K:BB in 12.2 innings. Though his results on the farm have been unremarkable, Giolito has been able to steadily increase his workload, with his five innings and 65 pitches Sunday both representing new highs. Giolito is expected to require one more tune-up outing in the minors before returning from the 15-day injured list and potentially slotting into the Red Sox rotation as soon as April 30. Since signing with the Red Sox in December 2023, Giolito has yet to make his team debut after missing the entire 2024 season while recovering from an internal brace surgery on his right elbow and then tweaking his left hamstring during spring training.

Giolito's (hamstring) rehab appearance with Double-A Portland on Sunday is expected to be followed by at least one more minor-league outing, Christopher Smith of MassLive.com reports.

EDGE Analysis

Red Sox manager Alex Cora said Sunday that Giolito will "probably" need another rehab outing following the veteran hurler's turn with Portland on Sunday. Giolito began his rehab stint by allowing just one run over 5.2 frames across his first two starts, but he was tagged for three runs over two innings his last time out April 15. The right-hander has struggled with his control so far, logging a 9:7 K:BB across his 7.2 frames. Boston is expected to get Brayan Bello (shoulder) back in the rotation Tuesday, making Giolito's return slightly less urgent, though Kutter Crawford (knee) and Richard Fitts (pectoral) also remain out.

Giolito (hamstring) struck out four and gave up three earned runs on five hits and three walks over two innings in his rehab start Tuesday with Double-A Portland.

EDGE Analysis

Due to poor weather being in the forecast at Triple-A Worcester, Giolito moved down a level for his third rehab start after making his previous two appearances with Boston's top affiliate. The drop in competition didn't make things any easier for Giolito, who struggled to command his arsenal and spotted just 34 of his 60 pitches for strikes. The right-hander has hovered between 51 and 64 pitches in each of his three rehab starts and has yet to pitch on less than five days' rest, so he could stay in the minors for another outing or two to push up his pitch count and shake off some more rust. Giolito was placed on the injured list after suffering a low-grade left hamstring strain in mid-March, but he also missed the entire 2024 season while recovering from an internal brace procedure on his right elbow.

Red Sox manager Alex Cora indicated Monday that Giolito (hamstring) is likely to make two more rehab starts, Gabrielle Starr of the Boston Herald reports.

EDGE Analysis

Giolito will make his third rehab start with Triple-A Worcester on Tuesday and is due for another one after that. It sets him up for his Red Sox debut as soon as April 25, although that date is not set in stone. Giolito missed the 2024 season following an internal brace surgery on his elbow and got a late start to this season because of a left hamstring strain.

Giolito (hamstring) is scheduled to start Tuesday for Triple-A Worcester, Chris Cotillo of MassLive.com reports.

EDGE Analysis

Both Giolito and Brayan Bello (shoulder) will get at least one more start for the WooSox before the team decides on the next step for each pitcher. Giolito, who threw 64 pitches over 3.1 innings in his last rehab start, believes he only needs one more before being ready to return to Boston, though he admitted that the decision is out of his control, Sean McAdam of MassLive.com reports.

Giolito (hamstring) allowed one earned run on three hits and three walks while striking out three over 3.1 innings for Triple-A Worcester on Wednesday.

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 threw 51 pitches over 2.1 innings Wednesday in his first rehab start with Triple-A Worcester and will need at least a couple more rehab outings as he continues to build up. The right-hander is coming back from a strained hamstring and has not made a major-league start since 2023, having missed the 2024 campaign while recovering from an internal brace procedure.
