The Rockies claimed Peralta off waivers from the Brewers on Saturday, Todd Rosiak of the Milwaukee Journal Sentinel reports.

Peralta lost his spot on Milwaukee's 40-man roster when the Brewers acquired outfielder Luis Matos earlier in the week, but the former will now claim a 40-man spot in Colorado's organization. Peralta owns a 5.12 ERA and 1.71 WHIP over 45.2 innings in his big-league career, and he began the season at Triple-A Nashville and allowed three earned runs over one inning across two appearances. The Rockies will option him to Triple-A Albuquerque.

Bernardino will serve as the Rockies' opening pitcher Saturday against the Phillies.

The Phillies typically use lefty sluggers Kyle Schwarber and Bryce Harper atop their lineup, so the Rockies will counter by sending the left-handed Bernardino to the mound for the first inning. The 34-year-old has fired three scoreless innings to begin the season, giving up two hits, no walks and striking out one batter in the process. Chase Dollander is expected to pitch in bulk relief once Bernardino exits the game.

Miller allowed two earned runs on two hits and a walk while striking out one across two-thirds of an inning in Friday's 10-3 loss to the Mets.

Miller had allowed just one hit and one walk in his first 1.2 innings of the season, but he struggled Friday. The left-hander entered in the ninth inning and issued a walk to the first batter he faced before surrendering an RBI double. He then gave up a single and another run before exiting. Over three outings, Miller has recorded a 7.71 ERA, 2.14 WHIP and 2:2 K:BB across 2.1 innings.

Raley struck out one in a scoreless two-thirds of an inning of relief to record his second hold of the season in Friday's win over the Giants.

The southpaw took over for Nolan McLean with one out in the sixth inning and runners on second and third, and Raley struck out Rafael Devers before getting Luis Arraez to ground out. Raley's had a strong start to the season as the top left-hander in the Mets' bullpen, posting a 0.00 ERA and 5:0 K:BB over 3.2 innings.

Slaten struck out one over a perfect inning to earn a hold in Friday's 5-2 win over San Diego.

Slaten pitched a 1-2-3 eighth inning to earn his second hold in three appearances this season, both of which set up saves for closer Aroldis Chapman. Coming off a 2025 season affected by a shoulder injury, a healthy Slaten will be a vital piece of the bullpen's setup crew in 2026.

Jackson signed a minor-league contract with the Mets on Saturday, Jon Heyman of the New York Post reports.

Jackson finished the 2025 season with a 4.06 ERA and 1.35 WHIP across 51 total innings, but he began to find consistent success toward the end of the year, posting a 2.38 ERA and 0.88 WHIP over 11.1 frames with the Mariners. Although he won't be granted a spot on the big-league roster immediately upon signing with the Mets, he could potentially earn a spot in Queens if he continues to find success at Triple-A Syracuse.

Armstrong struck out one over a scoreless inning to pick up a hold in Friday's 4-1 win over the Cubs.

Armstrong worked a 1-2-3 eighth inning, his first appearance without allowing baserunners, to earn his third hold of the season. After giving up a home run in his initial outing, Armstrong hasn't allowed a run in four subsequent appearances (3.2 IP). The right-hander has allowed five base runners during the scoreless streak but has managed to work around the traffic.

Speier picked up his first save of the season Friday against the Angels, allowing one unearned run with no hits or walks while striking out one across one inning.

Speier came on to pitch the 10th inning after Andres Munoz pitched a scoreless ninth inning in a tie game. Speier allowed the designated runner, Oswald Peraza, to score following a groundout and sacrifice fly but closed the door by striking out Yoan Moncada. Speier has a 5.40 ERA and 4:0 K:BB across 3.1 innings to begin the season.

Munoz (1-0) picked up the win Friday against the Angels, striking out three across a scoreless and hitless inning.

With the game knotted at 0-0 in the bottom of the ninth inning, Munoz came on for Seattle and promptly struck out Oswald Peraza, Zach Neto and Mike Trout on 19 pitches. The Mariners plated three runs in the top of the 10th inning, and Gabe Speier came on to close it out for Seattle, securing the win for Munoz. Through three appearances, Munoz has a 6.00 ERA and 6:0 K:BB across three innings. He's still looking for his first save.

Martin (1-1) picked up the loss Friday, allowing two runs on two hits over one inning in a 5-3 loss to the Reds.

Martin entered a 3-3 game in the top of the ninth inning and left with Texas trailing. He gave up a leadoff double to Spencer Steer followed by a Tyler Stephenson two-run home run. Martin, who entered the season as part of a closer committee, has allowed five runs (four earned) over 2.2 innings. All five runs crossed the plate in the ninth inning of games.
