Peralta was optioned to Triple-A Albuquerque on Thursday.

Peralta will head back to Albuquerque after serving as the Rockies' opener in Tuesday's 10-0 loss to the Rangers, giving up two runs on two hits and two walks while striking out a batter and hitting another over two-thirds of an inning. In corresponding move, Blas Castano was recalled from Triple-A to replace Peralta in the big-league bullpen.

Castano was called up from Triple-A Albuquerque on Thursday.

Castano will return to the big-league club just a few days after being sent down to Albuquerque on Monday. The right-hander will replace Sammy Peralta in the Rockies' bullpen after Peralta was optioned to Triple-A.

Williams secured the save Thursday against the Nationals, allowing one hit and no walks in a scoreless ninth inning. He struck out one.

Williams let the possible tying run get into scoring position via a Daylen Lile double but held on to preserve a one-run win for the Mets on Thursday. That's now 10 consecutive scoreless outings for the right-hander, who has nailed down five straight save opportunities. Williams' stats are still recovering from a brutal start to the year, as he now has a 4.32 ERA, 1.44 WHIP and 25:8 K:BB over 16.2 innings while converting seven of his eight save chances.

Smith was not given the save opportunity in Thursday's 3-1 win over Tigers.

Smith remains locked in as Cleveland's closer, but he recorded saves each of the previous two games and was unavailable Thursday after burning 36 pitches in those contests. Hunter Gaddis worked around a hit while striking out two in picking up his first save of the season.

The Red Sox optioned Kelly to Triple-A Worcester on Thursday, Chris Cotillo of MassLive.com reports.

Kelly had been solid out of the bullpen for Boston with a 3.31 ERA, 1.29 WHIP and a 14:7 K:BB through 17 appearances. The demotion is a mild surprise given that the right-hander had been great in his last 12 games with a 1.64 ERA and 11 strikeouts. He seems likely to get another look in the majors later this season.

The Red Sox will call up Guerrero from Triple-A Worcester prior to Friday's contest versus the Twins, Francys Romero of BeisbolFR.com reports.

It's a story of perseverance for the 35-year-old Guerrero, who has not pitched in the big leagues since 2019. He's earned the promotion by collecting a 0.92 ERA and 22:6 K:BB over 19.2 innings while notching three saves with Worcester. It's unclear what the corresponding move will be in order to free up a roster spot for Guerrero.

Devenski (illness) was cleared to resume all baseball activities last week and began throwing bullpen sessions May 13, Colin Beazley of the Pittsburgh Post-Gazette reports.

Devenski was placed on the shelf May 7 due to an unspecified illness, but he seems to be making good progress in his recovery. The veteran right-hander could be cleared to head out on a brief rehab assignment in the coming days before returning from the 15-day injured list.

Hurt notched a hold against the Padres on Wednesday, allowing two hits and striking out one batter over one scoreless inning.

Hurt was deployed in a high-leverage situation, entering in the eighth frame with the Dodgers up 3-0. He allowed two singles (one of which was an infield hit) but managed to get out of the inning unscathed in the scoring column by inducing a double play. Hurt gave up a run in his first outing of the season (April 15 versus the Mets) but has since tossed 13 straight scoreless frames over 13 appearances, posting a dominant 0.69 WHIP and 14:2 K:BB during that span. Hurt didn't record a hold in any of his first nine outings but has two over six appearances since. Given how effective he's been, he may be looking at more frequent high-leverage work moving forward.

Treinen pitched a perfect inning and picked up his sixth hold while striking out a batter in a 4-0 win over San Diego on Wednesday.

Treinen entered in the seventh inning and retired the side in order, maintaining the 3-0 lead for the Dodgers. The 37-year-old's scoreless inning marked his fifth such frame in his past six appearances. The right-hander has a 3.31 ERA, 1.35 WHIP and 15:6 K:BB through his first 16.1 innings while filling a setup role that's helped net him six holds.

The Diamondbacks released Curtiss on Friday.

After making 30 appearances out of the Arizona bullpen in 2025, Curtiss was outrighted off the Diamondbacks' 40-man roster in November and ended up re-signing with the organization on a minor-league deal. He failed to win a spot in Arizona's Opening Day bullpen and hadn't made a case for a promotion while pitching at Triple-A Reno, where he posted a 4.02 ERA, 1.32 WHIP and 13:6 K:BB across 15.2 innings over 12 appearances. Now a free agent, the veteran right-hander will look to catch on elsewhere.
