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.

Harvey (0-1) allowed three runs on two hits and a walk while retiring just two batters in relief to take the loss Friday against the Guardians.

Both of the hits Harvey allowed left the yard, as he served up a solo home run to Gabriel Arias and a two-run shot to Chase DeLauter in the seventh inning in an eventual 4-1 defeat for the Cubs. The righty reliever had tossed 2.1 scoreless frames across his first two appearances with his new team, but Friday was a step backward. Harvey should be able to rebound, and he's still positioned as a key setup arm in Chicago ahead of closer Daniel Palencia.

Sewald (0-1) was tagged with the loss Friday, allowing two runs on two hits while striking out one over two-thirds of an inning in a 2-0 loss to Atlanta.

Sewald entered a scoreless game in the top of the ninth inning and ceded back-to-back home runs. It was the first hiccup in four outings for Sewald, who had not allowed a baserunner in his first three appearances.

Dominguez (1-1) allowed one run (none earned) on no hits and no walks while striking out two over 1.1 innings to earn the win Friday against the Blue Jays.

Dominguez entered the game with the score tied and two outs in the ninth inning, and he was able to strike out Kazuma Okamoto to strand a runner at second. He then stayed in the game for the 10th frame, with the only run allowed coming due to a throwing error by Miguel Vargas. This was a needed showing from Dominguez, as he hadn't made an appearance since blowing a save chance and recording only one out Sunday against the Brewers.

Iglesias pitched a perfect inning to earn the save in Friday's 2-0 win over Arizona.

Iglesias came away with his first save of the season after he protected the two-run lead Atlanta established in the top of the ninth inning. The 36-year-old has allowed just one hit over three innings, though he's struck out only one batter and walked none so far. Osvaldo Bido had Atlanta's only other save prior to Friday, but that was a three-inning one. Iglesias is the favorite for the traditional closer role early in the year, though Robert Suarez is also an experienced option after primarily working the ninth inning with the Padres over the previous two seasons.
