The Giants placed Sanmartin (hip) on the 60-day injured list Wednesday.

The southpaw will be sidelined until June after suffering a right hip flexor strain earlier this month. Even when healthy, Sanmartin is not a lock to return to the active roster with the big club.

Atlanta placed Hernandez on the 15-day injured list Wednesday due to a right shoulder sebaceous cyst.

Hernandez didn't pitch after Sept. 6 last season due to right shoulder inflammation, and the issue seems to have lingered into 2026. He didn't make any appearances in spring training, though he was seen throwing a live batting practice session at camp last week. Assuming he hasn't experienced any setbacks since he resumed facing hitters, Hernandez could be cleared to head out on a rehab assignment once the minor-league season gets underway this weekend.

Atlanta placed Young (elbow) on the 15-day injured list Wednesday.

Young is unlikely to be ready to make his season debut for Atlanta until later this summer while he works his way back from Tommy John surgery, which he underwent back in May. The southpaw reliever could be shifted to the 60-day IL at some point when Atlanta needs to open up another spot on the 40-man roster.

The Astros placed Sousa (oblique) on the 15-day injured list Wednesday.

Sousa will get a late start to the season after tweaking his oblique in mid-March. He collected a 2.84 ERA, 1.03 WHIP and 59:15 K:BB across 50.2 innings in 2025 and will fill a key relief role again for the Astros, once healthy.

The Royals placed Kolek (oblique) on the 15-day injured list Wednesday.

Kolek strained his left oblique in late February. He's been throwing off a mound and appears close to returning to game action, though the righty could be assigned to Triple-A Omaha rather than the major-league club once he's healthy.

The Reds placed Ferguson (oblique) on the 15-day injured list Wednesday.

Ferguson will get a late start to the season after tweaking his right oblique in mid-March. Once healthy, he's expected to fill a middle-relief role in the Cincinnati bullpen.

The Dodgers placed Stewart (shoulder) on the 15-day injured list Monday.

Stewart is still working his way back from a right shoulder debridement procedure he underwent last September. The right-handed reliever has been throwing off a mound and the hope is his stay on the injured list will be brief.

The Dodgers placed Graterol (shoulder) on the 15-day injured list Monday.

Graterol didn't make any spring training appearances and has had difficulty regaining velocity since undergoing right shoulder surgery in November 2024. He's been throwing, but it's unclear when he might be an option for the Dodgers bullpen.

Atlanta released Nelson on Thursday.

Nelson signed a minor-league contract with Atlanta in late February but won't end up sticking around in the organization once the season gets underway. The veteran left-hander will likely seek out a minor-league deal elsewhere with the hope of pitching well enough at the Triple-A level to earn another opportunity in the big leagues. Nelson made three appearances in the majors with Arizona in 2025, giving up two earned runs on one hit and four walks over two innings.

Triple-A Gwinnett placed Kerr (elbow) on its 60-day injured list March 18.

After undergoing Tommy John surgery in the summer of 2024, Kerr appeared to be back to full strength for spring training, as he made a one-inning Grapefruit League appearance Feb. 24. He didn't pitch in any games after that, however, with Lindsay Crosby of BravesToday.com relaying that Kerr will require additional rehab from elbow surgery before returning to action at Gwinnett.
