Hoffman picked up his second save in Tuesday's 5-3 win over the Nationals, striking out one in a perfect ninth inning.

Hoffman needed just eight pitches to set the Nationals down in order. He's had no trouble yet in three appearances early on, allowing just two hits with a 4:0 K:BB.

Wesneski (0-1) took the loss after giving up three runs on two hits and three walks in five innings Tuesday against the Giants. He struck out six.

Although he allowed only two hits Tuesday and was able to throw two scoreless innings to open the game, Wesneski yielded two walks to begin the third frame and saw Willy Adames drive them in via a two-run double. Heliot Ramos then belted a leadoff homer to start the fourth inning. The 27-year-old right-hander will look to lower the amount of loud contact in his next scheduled start, which is tentatively set for early next week in Seattle.

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

Seattle optioned right-hander Emerson Hancock to Triple-A in a corresponding move, creating an opening in the rotation until George Kirby (shoulder) is ready to return from the injured list. Though Diaz will give the Mariners a fresh arm out of the bullpen in the short term, he could be a candidate to fill the vacant rotation spot if he's had sufficient rest by the time Seattle next requires a fifth starter. Diaz previously started in 23 of his 24 appearances for Tacoma in 2024, logging a 4.73 ERA, 1.52 WHIP and 120:54 K:BB over 118 innings.

Blue Jays manager John Schneider said Monday that Lucas is "Plan A" to start Wednesday versus the Nationals, Keegan Matheson of MLB.com reports.

As long as he isn't needed in relief Tuesday, Lucas will take the ball Wednesday in what would be his first major-league start. He's filling the spot that opened up when Max Scherzer (thumb) was placed on the injured list, and the lefty could be needed for additional starts while Scherzer recovers. Lucas built up to 2.2 innings and 42 pitches during spring training, so he might struggle to work deep enough into Tuesday's contest to qualify for a win.

The Astros acquired Robertson from the Blue Jays on Tuesday in exchange for Edinson Batista, Chandler Rome of The Athletic reports.

Robertson had been booted from Toronto's 40-man roster and now will report to Triple-A Sugar Land, where he will provide relief depth for Houston. The 26-year-old has made 27 appearances at the major-league level, compiling a 5.30 ERA and 40:11 K:BB in 35.2 innings.

Hahn re-signed Thursday with the Mariners on a minor-league deal.

After the Mariners released him March 23, Hahn was a free agent for just a few days before deciding to stick around in the organization as a depth arm out of the bullpen. He reported to Triple-A Tacoma and made his season debut Sunday, giving up one hit in a scoreless inning of relief.

Castro (elbow) struck out two batters over 1.1 perfect innings of relief Saturday in Triple-A Scranton/Wilkes-Barre's 5-4 loss to Lehigh Valley.

Castro enters the 2025 season at full health after he didn't pitch in 2024 while completing his recovery from June 2023 Tommy John surgery. The 26-year-old right-hander previously saw big-league action in the 2021 and 2022 seasons, making a combined 20 appearances between stops with the Giants and Cubs.

The Yankees signed Ottavino to a one-year contract Tuesday.

Ottavino failed to make the Red Sox's Opening Day roster after signing a minor-league contract, but he's now joined their rival on a big-league pact. The veteran reliever is absorbing the roster spot vacated by Devin Williams, who was placed on the paternity list. Ottavino held a 4.34 ERA and 70:23 K:BB over 56 innings for the Mets in 2024.

The Yankees placed Williams on the paternity list Tuesday.

Williams will be away from the Yankees for anywhere between one and three games while he welcomes a new addition to his family. He made his Yankees debut over the weekend against his former Brewers squad, notching a save Thursday during a rocky ninth inning in which he yielded one earned run on two hits and one walk wile striking out two batters. Luke Weaver could step in as the Yankees' interim closer during the team's three-game home series versus the Diamondbacks if Williams ends up missing all of those games.

Garcia struck out two in a perfect ninth inning Monday to record his first save of the season in a win over the Nationals.

Jeff Hoffman had pitched Saturday and Sunday, so Garcia got the call to protect a three-run lead Monday. The 34-year-old righty has been busy himself to begin the year, appearing in three of the Jays' first five games and posting a 4:0 K:BB over three scoreless innings. Garcia is locked into a high-leverage role and should see a handful of save opportunities the rest of the season when Hoffman is unavailable.
