The Diamondbacks placed Gallen on the 15-day injured list Friday due to a right hamstring strain.

EDGE Analysis

Gallen was pulled from Thursday's start against the Mets after throwing just six pitches without recording an out. He has been dealing with a right hamstring issue since April 26, and the 28-year-old right-hander will now be on the shelf for an extended period of time after aggravating the injury. It's unclear how long Gallen will be sidelined, but if he only misses the minimum, that would put him in line to return June 15 against the White Sox. In a corresponding move, the Diamondbacks recalled right-hander Slade Cecconi from Triple-A Reno.

EDGE Analysis

Gallen left Thursday's start with trainers after only 13 pitches as he aggravated a hamstring injury that originally popped up April 26. An exact return timeline is unclear, but he'll almost certainly miss at least one start and is likely to end up on the injured list.

Gallen exited Thursday's start against the Mets with an apparent injury, Jesse Friedman of GoPHNX.comreports.

EDGE Analysis

Gallen threw only 13 pitches and failed to record an out before being pulled from the contest. More information should be available after Thursday's game, though he has battled hamstring tightness a few times this season, most recently on May 18.

Gallen (5-4) allowed three runs on eight hits and a walk while striking out five over seven innings to take loss versus the Marlins on Friday.

EDGE Analysis

Gallen had his longest outing of the season and his fourth straight quality start, but the Diamondbacks couldn't get anything going as Miami starter Braxton Garrett tossed a shutout. Gallen has permitted more than three runs just once in 10 starts this season, pitching to a 3.12 ERA, 1.13 WHIP and 60:15 K:BB over 57.2 innings. He's projected to make his next start on the road versus the Rangers.

Gallen revealed after Saturday's start against the Tigers that his right hamstring tightened up on him during the fourth inning, Jesse Friedman of GoPHNX.com reports.

EDGE Analysis

It's the same hamstring that he had issues with earlier this season, resulting in an early removal from one start and having another pushed back. Gallen wound up pitching into the seventh inning Saturday, ultimately getting charged with three runs on seven hits while striking out 10 over 6.2 frames. The right-hander said after the outing that his hamstring feels fine and he's unconcerned. Still, given that it's been a recurring problem, it's something to keep in mind.

Gallen (5-2) picked up the win Sunday against Baltimore, allowing two runs on four hits and two walks across six innings. He struck out four.

EDGE Analysis

Gallen notched a second straight quality start, following up a one-hit gem against the Reds with Sunday's two-run showing against the O's. Three of the four hits against Gallen went for extra bases, as he allowed doubles to Anthony Santander and Jordan Westburg while Adley Rutschman slugged a solo homer in the sixth. Gallen owns a 2.86 ERA and a 1.11 WHIP across 44.0 innings in 2024. He's lined up for a home start against the Tigers next weekend.

Gallen (4-2) earned the win Tuesday over the Reds, allowing one hit and three walks over six scoreless innings. He struck out six.

EDGE Analysis

Gallen had gone 11 days between starts after suffering a hamstring injury on April 26 against Seattle. He certainly looked healthy Tuesday, holding Cincinnati to one hit en route to his third scoreless outing this season. It's an encouraging effort from Gallen, who'd dropped his previous two starts, allowing eight runs over 10 innings in that span. He lowered his ERA to 2.84 with a 1.13 WHIP and 41:12 K:BB across seven starts (38 innings) this year. Gallen's currently in line for a road start Sunday against the Orioles in his next outing.

Manager Torey Lovullo said after Wednesday's 8-0 loss to the Dodgers that Gallen (hamstring) will make his next start Tuesday against the Reds, Jesse Friedman of GoPHNX.com reports.

EDGE Analysis

Gallen was removed from his most recent start last Friday with a hamstring injury. The Diamondbacks had tentatively planned for Gallen to start the series finale with the Dodgers, but he ultimately needed more time to heal up from the injury. Arizona will skip his turn in the rotation entirely this week, but he'll tentatively line up for two starts the following week. After his matchup with the Reds, Gallen would then be slated for a start May 12 in Baltimore.

Diamondbacks manager Torey Lovullo said Wednesday that Gallen (hamstring) won't start Friday as scheduled in an effort to provide him extra rest, Alex Weiner of ArizonaSports.com reports.

EDGE Analysis

The right-hander was originally set to start Wednesday, but Tuesday's starter Jordan Montgomery was pushed back a day since the start time was delayed two hours. Gallen apparently isn't having any issues with the hamstring injury that surfaced in his previous start, but Lovullo has still decided to give his ace some extra rest. The earliest Gallen will take the mound is Sunday versus the Padres, but it's possible he gets some additional time, as team off days Thursday and Monday give Arizona some flexibility.

Gallen (hamstring) will make his regularly scheduled start Wednesday against the Dodgers, Alex Weiner of ArizonaSports.com reports.

EDGE Analysis

Gallen's bullpen session earlier in the day went well, and skipper Torey Lovullo confirmed late Monday evening that the right-hander will indeed take the mound Wednesday after exiting his previous outing Friday due to hamstring spasms. Gallen owns a 3.38 ERA and 1.22 WHIP with a 35:9 K:BB across 32 innings this season.
