Houston Astros starting pitcher Hunter Brown (right shoulder) initially felt something in his shoulder on Friday, manager Joe Espada told Brian McTaggart of MLB.com. He had some imaging done in Sacramento before flying back to Houston to be evaluated by team doctors. After being evaluated, Brown was placed on the 15-day injured list with a right shoulder strain, retroactive to April 2. It's a crushing loss for the Astros. Brown is their ace and had been off to a 1-0 start with a 0.84 ERA through two starts. Across 10.2 innings of work, he has allowed five hits and six walks while striking out 17 batters. The team hasn't provided a timeline for his return, nor have they clarified who will take his spot in the rotation. Christian Roa was called up to fill his void on the 26-man roster, but he hasn't started a game since 2024 in the minors.

New York Mets first baseman Brett Baty (thumb) was a late scratch after initially appearing in the starting lineup for Sunday's game against the San Francisco Giants. Manager Carlos Mendoza told Andrew Tredinnick of USA Today that Baty is dealing with a sore left thumb after jamming it on a slide on Saturday. The injury is not believed to be serious, and there's a strong chance that the 26-year-old will get back into the lineup on Tuesday. Baty is off to a slow start at the plate, slashing .242/.242/.364 with zero home runs, zero walks, and a 30.3% strikeout rate so far. He has primarily played first base but also has three appearances at designated hitter and two in right field. Mark Vientos will start at first base in his absence on Sunday, and Jorge Polanco (Achilles) is back in the lineup as the designated hitter.

Miami Marlins right-handed pitcher Pete Fairbanks will serve as the opener for Sunday's game against the New York Yankees. After the game, he will be placed on the paternity list. Fairbanks has been excellent, as per usual, in his role as the Marlins' closer early this season. Through three relief appearances, he has a 0.00 ERA, -0.15 FIP, five strikeouts, one hit, zero walks, and two saves. He won't be up for a save opportunity on Sunday, but rather will be tasked with setting an early tone against the top half of the Yankees' lineup. Marlins fans will have to be patient, though, as the start of Sunday's game has been delayed due to rain. As it stands, Fairbanks ranks as the #13 reliever in RotoBaller's latest fantasy baseball rankings for 2026.

The Los Angeles Angels have selected the contract of right-handed pitcher George Klassen. He will be the Halos' starting pitcher on Sunday, making his MLB debut against the Seattle Mariners. Klassen was the Phillies' sixth-round pick in 2023, but he made his way to the Angels organization via trade in 2024. He posted an impressive 3.29 FIP and 11.05 K/9 at Double-A last year, but he did have an issue with walks. He was roughed up with a 7.94 FIP over 14 innings in spring training, but he posted a solid 4.2-inning start in Triple-A last week. He'll start for the Angels on Sunday after Ryan Johnson (illness) was scratched. Klassen throws an upper-90s fastball and puts effective break behind both his slider and cutter. It will be interesting to watch how the stuff plays against a star-studded Seattle lineup featuring Julio Rodriguez and Cal Raleigh.
