Baltimore Orioles right-hander Zach Eflin (lat) will throw a side session on either Friday or Saturday, according to manager Brandon Hyde. Eflin has been cleared to throw off a mound this weekend for the first time since suffering a right-lat strain back on April 7. The 31-year-old might require several minor-league rehab starts after he throws a couple of bullpen sessions, though, which means we probably won't see him come off the 15-day injured list and rejoin Baltimore's starting rotation until some point in early May, barring a setback. Before his injury, Eflin had a 3.00 ERA and 0.83 WHIP with eight strikeouts and only one walk in 18 innings pitched over his first three starts in 2025. When healthy, Eflin still has fantasy value in mixed leagues, although there isn't a ton of upside after he showed a dip in his strikeout rate a year ago with Tampa and Baltimore.

Arizona Diamondbacks manager Torey Lovullo said that "all indications" are that right-handed reliever Justin Martinez (shoulder) will be available out of the bullpen for Tuesday's game against the visiting Tampa Bay Rays. "I feel very strongly that today could be the day for him to come back," Lovullo said. Martinez hasn't pitched since last Thursday due to right-shoulder fatigue, but it appears the 23-year-old high-leverage reliever won't need a trip to the injured list just yet. Left-hander A.J. Puk (elbow) went on the injured list on Saturday, which led to Drey Jameson picking up the save on Sunday when Martinez was unavailable with what could be a case of early-season dead arm. If Martinez gets past the issue, he should be first in line for save opportunities in the back end of Arizona's bullpen until Puk is able to return. Martinez hasn't allowed a run in his first seven innings with 10 K's and two saves.

Boston Red Sox infield prospect Marcelo Mayernotched his fifth consecutive multi-hit performance in Game 1 of Wednesday's doubleheader for Triple-A Worcester, then followed that up with a sixth straight multi-hit effort in Game 2. The left-handed slugger was 4-for-6 on the day with a walk, a home run, two RBI, and a run scored, now slashing .277/.318/.518 with six home runs and a minor-league-leading 26 RBI through 20 games. There's no clear path to playing time for the 22-year-old, however, he was at DH in Game 1 and at second base in Game 2; with shortstop being his primary position, it's possible he could have some sort of utilityrole whenever he gets the call in order to get him major leagueat-bats. As long as he stays hot, the closer his debut becomes, so fantasy managers should stay vigilant if looking for offensive help.

Tampa Bay Rays outfielder Jake Mangum (groin) left Wednesday's game in the fourth inning due to left groin tightness, according to Marc Topkin of the Tampa Bay Times. He left the game after pulling up while running to first base. The extent of the injury isn't yet known, but more information will be available after he's evaluated further. He's been great so far in the early going of 2025, slashing .338/.384/.397 through 21 games. He hasn't homered yet but is a major threat on the base paths with eight stolen bases. Hopefully the groin issue doesn't impact that speed moving forward.

Chicago Cubs relief pitcher Ryan Pressly (knee) had his right knee drained on Tuesday night, according to manager Craig Counsell. He hopes for him to be available on Friday. Pressly hasn't pitched since Sunday and was noticeably absent in Wednesday's 7-6 win over the Dodgers, where Porter Hodge picked up his first save of the season. Luckily, the injury doesn't appear to be serious if the Cubs are anticipating a return in a couple of days. He's been solid in the closer role in 2025, posting a 2.45 ERA with four saves through 11 appearances.
