Walter was optioned to Triple-A Worcester on Saturday.

Walter's latest big-league stint lasted seven days. It won't be one he remembers fondly, as he gave up 11 runs in 5.1 innings of work across a pair of relief appearances. Zack Weiss was called up to take his place on the roster.

Weiss was recalled from Triple-A Worcester on Saturday.

Weiss will get his first chance to pitch in a Red Sox uniform after being claimed off waivers from the Angels in late August. The 31-year-old righty owns a 5.79 ERA in 18.2 career MLB innings.

Cox was placed on the 60-day injured list with a sprained left knee Saturday.

Cox suffered the injury while running to cover first base after getting hit by a comebacker Friday against Toronto. The team believes he suffered some sort of ACL injury, per Joel Goldberg of Bally Sports Kansas City, and he'll receive an MRI on Sunday to determine the extent of the damage. He'll finish his rookie season having recorded a 4.79 ERA, 1.29 WHIP and one save in 35.2 innings.

Hernandez (1-10) allowed three runs on two hits and two walks over one-third of an inning, taking the loss and a blown save Friday versus the Blue Jays.

Austin Cox started the eighth inning but sustained a left knee injury after facing two batters. Hernandez proceeded to allow an inherited runner to score before getting tagged for three runs himself. He has three blown saves and two saves over his last seven appearances, a span in which he's allowed six runs over six innings. He's at a 4.81 ERA, 1.19 WHIP and 74:25 K:BB with three saves, 12 holds and five blown saves through 63.2 innings this season. Hernandez should continue to see high-leverage looks, but the quality of his performance of late puts him on the fantasy fringe.

Marinaccio was called up by the Yankees on Saturday.

Marinaccio owns a 4.08 ERA in 46.1 major-league innings this season, with a 27.6 percent strikeout rate more or less canceling out an inflated 12.6 percent walk rate. He'll give the Yankees an extra bullpen option, taking the roster spot that had belonged to Luis Severino, who landed on the injured list with a side injury.

Thornton will serve as the Mariners' opening pitcher Saturday against the Rays, Daniel Kramer of MLB.com reports.

Like many relievers, Thornton broke into the big leagues as a starter, but he's pitched exclusively in relief for the past three seasons, while his three "starts" in 2021 were similar opener appearances. Thornton has thrown two innings in both of his last two appearances, but he's unlikely to throw much more than that Saturday before turning the game over to Luke Weaver, who is expected to work in bulk relief.

Romano gave up a run on a hit and two walks in 1.1 innings Friday to record his 33rd save of the season in a 5-4 win over the Royals. He struck out one.

The right-hander was called in to handle a bases-loaded, two-out situation in the eighth inning, and while he quelled that rally by the Royals, Romano created his own in the ninth by walking two of the first three batters he faced before finally escaping the jam. After a string of nine straight scoreless appearances, Toronto's closer has been tagged for a run in two straight outings, but on the season he still sports a 2.65 ERA, 1.18 WHIP and 62:21 K:BB through 51 innings, with more wins (five) than blown saves (three).

Clase pitched a perfect inning to earn the save in Friday's 6-3 win over the Angels. He did not strike out a batter.

Clase needed 15 pitches to complete the clean inning just a day after he was tagged for two runs in two-thirds of an inning in a blown save. The right-hander still leads the majors with 39 saves, but he's also blown 10 chances in a less-than-dominant campaign. He has a 3.02 ERA, 1.13 WHIP and 58:15 K:BB through 65.2 innings this season.

McArthur will serve as the Royals' opener Saturday at Toronto, Jaylon T. Thompson of The Kansas City Star reports.

Zack Greinke is expected to enter the game behind McArthur as a bulk reliever. The 26-year-old has spent the majority of this season at the Triple-A level and carries a rough 10.13 ERA through his first 10.2 major-league innings.

May allowed a hit in a scoreless inning and earned the save in a win over the Rangers on Friday.

May coughed up a two-out single but still slammed the door to finish the 6-3 win. He's riding an 8.1-inning scoreless streak, lowering his season ERA to 3.79 through 40.1 frames. May has converted 19 of his 22 save opportunities this year, including nine straight.
