The Mariners optioned Simpson to Triple-A Tacoma on Wednesday, Shannon Drayer of SeattleSports.com reports.

Seattle called up lefty Jhonathan Diaz from Triple-A in a corresponding move, giving the Mariners a fresh arm in the bullpen. Simpson was unlikely to be available for another day or two after he needed 33 pitches to record two outs in his appearance during Tuesday's 22-0 loss to the Brewers. He gave up five runs on three hits and two walks in the outing, inflating his ERA to 9.82 and his WHIP to 2.05 over 7.1 big-league innings on the season.

The Mariners selected Diaz's contract from Triple-A Tacoma on Wednesday.

Diaz has spent the entire 2026 season in Triple-A, where he's produced a 6.22 ERA, 1.55 WHIP and 83:42 K:BB over 111.1 innings. He's been used in both the rotation and bullpen in his limited time in the majors over the last five seasons, but the Mariners will likely plan for Diaz to provide some extra coverage in relief after Josh Simpson and Nick Davila both tossed 30-plus pitches during Tuesday's 22-0 loss to the Brewers. Simpson was optioned to clear room on the active roster for Diaz.

The Dodgers designated Hernandez for assignment Wednesday.

Hernandez will be pushed off the Dodgers' 40-man roster for the second time in as many weeks to make room for Brock Stewart (shoulder), who returned from the injured list Wednesday. Hernandez has logged a 5.68 ERA and 1.34 WHIP across 25.1 innings in the majors this year and is likely to clear waivers again.

The Dodgers reinstated Stewart (shoulder) from the injured list Wednesday.

Stewart landed on the injured list at the end of July due to shoulder tendinitis, and he's now been cleared to rejoin the Dodgers' bullpen without playing in any rehab games. The 34-year-old lefty has given up just four earned runs in 14.2 innings this season, and he could be a candidate to pick up an occasional save while Edwin Diaz (neck) is on the injured list.

The Rockies reinstated Hill (shoulder) from the 15-day injured list Wednesday.

Right shoulder tendinitis has kept Hill out of action since late June, but he's now been cleared to return after spending nearly two months on the shelf. The 26-year-old posted a 5.06 ERA and 1.65 WHIP over 26.2 innings before getting hurt, but Colorado's lack of bullpen depth could allow him to work in high-leverage situations, as he already has two saves and 11 holds on the season. TJ Shook was optioned to Triple-A Albuquerque in a corresponding move.

The Rockies selected Manfredi's contract from Triple-A Albuquerque on Wednesday.

Manfredi joined the Rockies organization at the trade deadline as part of the deal that sent Antonio Senzatela to Milwaukee. The 26-year-old righty owns a 4.45 ERA and 1.38 WHIP across 28.1 innings at Triple-A this season but has given up six runs in just five frames with Albuquerque since being traded. Despite his recent performance, the Rockies will add him to their bullpen to provide a fresh arm. Parker Mushinski was designated for assignment in a corresponding move.

The Rockies optioned Shook to Triple-A Albuquerque on Wednesday.

Shook was recalled by the Rockies on Monday and pitched the same night against the Dodgers, allowing one run on two hits and one walk while striking out one batter across two innings. Colorado will shuffle its bullpen again Wednesday, with Shook going back down to the minors and left-hander Mark Manfredi coming up from Albuquerque to replace him. Shook has spent most of the 2026 season in Triple-A, where he has a 3.02 ERA, 1.33 WHIP and a 45:24 K:BB over 47.2 innings.

The Giants optioned Sanmartin to Triple-A Sacramento on Wednesday.

Sanmartin will be squeezed off the 26-man active roster after the Giants needed to clear a spot for lefty Matt Wilkinson, who was called up from Triple-A to start Wednesday's game in Cleveland. After being summoned from Sacramento on Aug. 3, Sanmartin made eight relief appearances during his latest stint with the Giants, pitching to a 7.11 ERA, 2.05 WHIP and 6:2 K:BB over 6.1 innings.

The Giants claimed Abner off waivers from the Diamondbacks on Wednesday and optioned him to Triple-A Sacramento.

Abner will reclaim a 40-man roster spot with the move to San Francisco, though he'll have to wait a bit before making his debut with the Giants. The 24-year-old lefty reliever made eight appearances with Arizona at the big-league level this season, posting a 6.28 ERA, 1.53 WHIP and 6:8 K:BB over 14.1 innings.

The Nationals optioned Cruz to Triple-A Rochester on Wednesday.

Cruz was part of the trade package that came back to Washington from the Yankees in the Aug. 3 deal that sent first baseman Luis Garcia to New York. In six appearances out of the Nationals bullpen, Cruz allowed five runs on nine hits and five walks with four strikeouts across four innings.
