Milwaukee Brewers outfielder Joey Wiemer (knee) has been activated from the 10-day injured list on Monday. The young outfielder was forced to miss 16 days due to left knee soreness. He wasn't playing too well before the injury but figures to at least play in a platoon role going forward. Wiemer will cover center field and bat ninth versus lefty Ryan Weathers on Monday.

Baltimore Orioles outfielder Anthony Santander (knee) is serving as the team's designated hitter and is batting fifth on Monday against the St. Louis Cardinals and right-hander Sonny Gray. Santander has been dealing with a bothersome bruised knee of late and was held out of Sunday's contest against the Seattle Mariners as a result. It mostly gives the 29-year-old issues while running the bases and in the outfielder, but Santander is apparently feeling good enough to DH for the series opener in St. Louis. In 10 career at-bats against Gray, Santander has only two hits, but one of them cleared the fences. The Venezuelan switch-hitter's power is attractive in fall fantasy leagues in the middle of a strong Baltimore lineup, but Santander has been inconsistent so far in 2024 and has gone 10-for-49 (.204) with three homers and seven RBI in 14 games so far in May.

Seattle Mariners shortstop J.P. Crawford (oblique) went through a pre-game warmup at Yankee Stadium on Monday and told the team he was ready to go. However, he's not in the starting lineup against the New York Yankees, and the Mariners are likely waiting to reinstate him from the injured list and return him to the starting lineup for the second game of the series on Tuesday. Dylan Moore is going to get one more game to serve as Seattle's starting shortstop. He's at the 6 and is batting sixth against Yankees right-hander Marcus Stroman. Crawford has been out since the end of April with a Grade 1 right-oblique strain but is on the cusp of a return. Fantasy managers in deeper leagues will be hoping Crawford can turn things around offensively when he's back, as he'll be returning to a .198/.296/.302 slash line with two homers and nine RBI.UPDATE: Crawford was activated from the injured list on Monday but wasn't included in the starting lineup.

Seattle Mariners manager Scott Servais said that second baseman Jorge Polanco (hamstring) will be available off the bench, if needed, against the New York Yankees in the Bronx. Josh Rojas is making another start at second base and will bat leadoff for the M's versus Yankees right-hander Marcus Stroman. Polanco is missing a fourth straight game due to a right-hamstring issue, but it appears he's getting close to a return and should avoid a trip to the injured list. The 30-year-old Dominican veteran has had a rough start to his first year in Seattle, as he's currently slashing .192/.298/.308 with five homers, 13 RBI and 15 runs scored in 146 at-bats. Rojas has exceeded expectations offensively for the M's but has come back down to Earth a bit in his last five games with just one hit and seven strikeouts in his 21 plate appearances.

Minnesota Twins outfielder Max Kepler is taking a seat on Monday with the team facing left-hander Mitchell Parker and the Washington Nationals. With Kepler getting a day off, Manuel Margot will draw into the starting lineup, playing right field and batting third for the Twins. The 31-year-old lefty-swinging Kepler has been solid in limited plate appearances against southpaws this year, but he's hit just .221 against them in over 1,000 career plate appearances. The German outfielder is hitting .303 (30-for-99) with three home runs, 17 RBI and 13 runs scored so far this year, but the underlying numbers show that he's due some regression in the average department eventually. Margot is hitting just .195 (17-for-87) this year with a homer and nine RBI, but he could be worth considering as a DFS sleeper against a young lefty out of the three-hole.
