Infielder Luis Arraez, acquired by the San Diego Padres for prospects on Friday night from the Miami Marlins, is in the designated hitter slot and is batting leadoff on Saturday night. Arraez is hitting .299 with no home runs, five RBI, and 22 runs in 148 plate appearances this season. Arraez could also see time at first base and second base in San Diego. The Padres face off against right-hander Brandon Pfaadt and the Arizona Diamondbacks on Saturday, and Arraez should be in all starting fantasy lineup. Although he lacks power, the move to a more potent lineup in San Diego is a boost to his fantasy value everywhere.

Baltimore Orioles outfielder Colton Cowser is out of the lineup for Saturday night's tilt against Andrew Abbott and the Cincinnati Reds. Ryan McKenna is starting in left field in Cowser's place. This shouldn't a cause for concern for fantasy owners as this appears to be Cowser being in a platoon situation. The lefty has only hit for a .348 OPS against southpaws in 2024. With Reds' lefty Nick Lodolo on deck for Sunday's game, Cowser shouldn't be expected to be back in the lineup until Tuesday in Washington against Nationals right-hander Trevor Williams.

Kansas City Royals starting pitcher Alec Marsh (elbow) is set for a rehab start with Triple-A Omaha on Sunday. Marsh is expect to throw between 60-65 pitches in the start. As of now it's unclear if Marsh will need multiple rehab starts before rejoining the Royals, so there is a chance that if all goes well then he will rejoin Kansas City when he can be activated off the IL on May 10th. Marsh had been having a solid season before getting drilled with a liner when facing the Toronto Blue Jays. The right-hander has posted up a 2.70 ERA and recorded three wins in five starts. Marsh may be a sneaky add that fantasy managers can stash on their bench until he returns.

Washington Nationals starting pitcher Josiah Gray (elbow) felt good after throwing a bullpen on Saturday, according to manager Dave Martinez. He threw around 30-35 pitches and will be throwing another bullpen on Tuesday or Wednesday. There currently isn't a timetable set for Gray's return or when to expect him to begin rehab starts, but this is a positive sign for the 26-year-old. Gray had a very rocky start to the 2024 season, giving up 13 runs in just over eight innings across two starts. With Gray out, the Nationals starters have posted a 4.40 ERA, though three of their starters have posted an ERA below 3.50. They will have to hold down the fort until Gray comes back.

The San Francisco Giants announced Saturday that they have placed catcher Patrick Bailey on the 7-day concussion injured list and have recalled catcher Blake Sabol from Triple-A Sacramento. Bailey was removed from Friday night's game after a foul tip on a 95 mph fastball hit off his mask in the bottom of the first inning. Tom Murphy will be starting in Bailey's place on Saturday night against the Philadelphia Phillies. Murphy is hitting for a .121 average and a .458 OPS. Sabol put up much better numbers in 2023, hitting for a .695 OPS in 344 plate appearances. While both catchers should be expected to split time while Bailey's out, Sabol should be the higher priority for the next week with the expectation that he will be more productive than Murphy. Both should make for good streaming options next week as the Giants open up a series at Coors Field against the Colorado Rockies on Tuesday.
