Minnesota Twins third baseman Royce Lewis (hamstring) will play 10 innings as the team's designated hitter during a doubleheader for Triple-A St. Paul on Tuesday, and then he'll play a full game at third base on Wednesday. Lewis could be an option to come off the injured list and play in Friday's series opener in Boston against the Red Sox, but The Athletic's Dan Hayes thinks it's likelier that he'll play a few more rehab games over the weekend and return when the Twins open a homestand on Tuesday, May 6, against the Baltimore Orioles. In two rehab games to this point, the 25-year-old right-handed power bat has gone 3-for-6 with a double and an RBI for St. Paul. Lewis initially strained his left hamstring in March 16 in spring training while running to first base, but he's on the cusp of his 2025 debut. He should be rostered in all fantasy formats for his high-end power stroke.

Minnesota Twins utility man Willi Castro (oblique), who is on the 10-day injured list with a right-oblique strain, continues to perform most baseball activities, including hitting from the right side. Castro will hit from the left side on Tuesday, which should give the team a better idea of whether he could return from the IL in time for the series opener against the Boston Red Sox on Friday. The 28-year-old is eligible to come off the IL on Thursday, but it remains to be seen if that will actually happen without Castro going on a short minor-league rehab assignment. The Puerto Rican switch-hitter was mostly playing third base at the time of his injury with Royce Lewis (hamstring) on the shelf, but when he returns, he could bounce around between the infield and outfield. Castro will be returning to a .227/.292/.364 slash line with just one homer, five RBI, a steal and seven runs scored in his 66 at-bats.

New York Mets infield prospect Ronny Mauricio (knee) went 1-for-3 with a stolen base and a strikeout during his first rehab outing with Single-A St. Lucie on Sunday. The 24-year-old missed the entire 2024 campaign after undergoing ACL surgery. In 2023, Mauricio made his MLB debut and held a .248/.296/.347 slash line with four doubles, two home runs, and seven stolen bases. Earlier in that season, Mauricio spent most of his time with Triple-A Syracuse, where he flashed high upside as he posted a .292/.346/.506 line with 30 doubles, 23 home runs, and 24 stolen bases. Fantasy managers should pay close attention to Mauricio's progress during his rehab outing, as he should be in the mix to return to the majors later this summer. When he returns to the big leagues, he could carry value in category formats, given his power and speed upside.

Minnesota Twins infield prospect Luke Keaschall (forearm) is expected to miss at least a "couple of months" of action. Keaschall suffered a forearm fracture during Friday's contest after being hit by a pitch. While the infielder could avoid surgery, he will remain sidelined for at least the foreseeable future. The 22-year-old has enjoyed an impressive start to his MLB career as he posted a .368/.538/.526 slash line with three doubles and five stolen bases through seven games. During the first 14 games of the Triple-A regular season, the No. 58-ranked prospect in the sport on MLB Pipeline held a .261/.379/.348 line with one home run and four stolen bases. While Keaschall remains sidelined, fantasy managers should expect Edouard Julien to see more opportunities at the keystone.

Atlanta Braves manager Brian Snitker said on Monday that he didn't have an update on outfielder Ronald Acuna Jr. (knee). Acuna has yet to make his 2025 debut after tearing his ACL last year, although he was cleared to ramp up his baseball activities a few weeks ago. The Braves always planned on taking things slow with the 27-year-old former MVP, so it's not that big of a surprise that there are no updates or that he hasn't started a minor-league rehab assignment yet. When we hear more on Acuna, we'll pass it along. For now, fantasy managers must remain patient and hope that he's able to return to the Braves starting lineup sooner than later in the month of May. Acuna still has the potential to be a difference-maker for fantasy teams, although he probably isn't going to run nearly as much on the basepaths. When he's ready, the Braves plan on returning Acuna to right field immediately.
