Arizona Diamondbacks first baseman Pavin Smith (elbow) was activated off the 60-day Injured List ahead of Monday's game against the Los Angeles Dodgers. Smith hasn't played since the opening series of the season after having surgery to remove loose bodies from his elbow. He'll serve as the designated hitter and bat fifth during his return on Monday. The expectation is that Smith will split up time between DH and first base against right-handed pitching. He slashed. 258/.362/.434 with eight home runs and 28 RBI last season. Smith could be a potential option in deep leagues. In a corresponding move, infielder Tim Tawa has been optioned to Triple-A.

San Francisco Giants relief pitcher Wilkin Ramos has been called up ahead of Monday's game against the Milwaukee Brewers. Ramos will serve as bullpen depth after a strong start to the season in Triple-A. Across 27 innings, Ramos posted a 2.00 ERA, 1.15 WHIP, and a 27:7 K:BB ratio across 17 appearances in the minors. He'll likely start in low-leverage spots, but Ramos could quickly earn his way up the depth chart in San Francisco. He's someone to keep an eye on as a potential closer candidate down the road.

Cincinnati Reds infielder Edwin Arroyo has been called up to make his MLB debut on Monday against the Kansas City Royals. Arroyo will join the big league roster with Elly De La Cruz (hamstring) landing on the 10-day Injured List. The rookie infielder will cover second base and bat eighth during his debut. Matt McLain will shift over to shortstop, but Arroyo could play over there as well. This season, Arroyo is slashing .323/.383/.562 with 11 home runs and nine stolen bases during his time in Triple-A Louisville. He could be worth an add in most fantasy formats, with everyday playing time likely coming his way while De La Cruz is on the shelf.

Cincinnati Reds shortstop Elly De La Cruz (hamstring) was placed on the 10-day Injured List on Monday. De La Cruz will head to the shelf for the first time during his MLB career. Reds manager Terry Francona said that De La Cruz is looking at missing 2-4 weeks of action due to a Grade 1-2 hamstring strain. The best-case scenario is that De La Cruz is back in the mix by mid-June, but hamstring injuries can be tricky. Matt McCain will take over at shortstop on Monday, with Edwin Arroyo making his MLB debut at second base. The expectation is that these two will split up most of the playing time at shortstop while De La Cruz is out. Fantasy managers will need to stay tuned for more updates on De La Cruz as he progresses.
