Washington Nationals third base prospect Brady House continued his push for a promotion to the majors, recording a two-homer game over the weekend and is now slashing .282/.344/.497 with eight home runs through 42 games at Triple-A Rochester. The former first-round draft pick has shown improved strikeout (26.1 percent) and walk rates (8.3 percent) compared to the 54 games he played at that level last season. The Nationals are using a combination of Jose Tena and Amed Rosario at third base at the moment. However, Rosario is more of a utility player, and Tena has yet to hit a home run through 95 plate appearances in 2025, so the Nats may soon be inclined to give their top offensive prospect a shot at the hot corner. With plus power, the 21-year-old is a stash candidate in deeper leagues. Look for him to be up by mid-June, if not before then.

New York Mets outfield prospect Carson Benge got off to a slow start at High-A Brooklyn this year, going 11-for-51 (.216) with three extra-base hits (all doubles) over his first 14 games. Since then, however, the 2024 first-round draft pick has gone 27-for-72 (.375) with 11 extra-base hits (five doubles, two triples, four home runs), a 12:15 BB:K, and has recorded all six of his stolen bases in the last 18 games. Currently riding a nine-game hit streak, the Mets' third-ranked prospect moved from No. 98 overall up to No. 89 on MLB.com's latest refresh of their top 100 prospects list and figures to see a promotion to Double-A before long. The left-handed slugger is a couple of years away from the big leagues, but could be a name for dynasty managers to monitor if he continues to hit well and climb up the prospect ranks.

San Diego Padres right-hander Joe Musgrove (elbow) has been traveling with the big-league team after starting to play catch again in early April. Musgrove is playing catch three times a week and is scheduled to progress from 75 feet to 90 feet this week, according to MLB.com. The 32-year-old veteran is recovering from Tommy John surgery to fix a torn right UCL. He was placed on the 60-day injured list on March 20 and will miss the entire 2025 season for the Padres and fantasy managers. Before injuring his elbow last year, Musgrove was no longer a reliable fantasy starter and posted a 6.37 ERA in his first eight starts. He looked better in two starts after returning, but that was the extent of his season before having to undergo TJ surgery. With better health, Musgrove could bounce back in 2026, but it's no sure thing at his age.

San Diego Padres right-hander Matt Waldron (oblique) made a minor-league rehab start in the rookie-level Arizona Complex League on May 15 and could move to Double-A San Antonio for his next rehab start. Waldron suffered a left-oblique strain while warming up in the bullpen before a spring training game and was moved to the 60-day injured list (retroactive to March 24) on March 27. MLB.com is estimating that he could make his 2025 season debut in the big leagues by June or July. In 1 2/3 innings in the ACL last Thursday, the 28-year-old knuckleballer gave up an earned run on two hits while walking one and striking out three. He threw 38 pitches in the outing and will likely need at least a few more starts before being under consideration for starting-rotation role at the big-league level. Fantasy managers in 12-team mixed leagues can continue to ignore Waldron.

Texas Rangers right-handed pitching prospect Kumar Rocker (shoulder) could start a minor-league rehab assignment later this week if he bounces back well from the two-inning live batting practice session he had on Sunday, according to The Dallas Morning News' Shawn McFarland. Manager Bruce Bochy said that Rocker looked "good" on Sunday, but the 25-year-old will have a lengthy rehab assignment because of the fact that he was shut down for three weeks while recovering from a right-shoulder impingement. Rocker is a must-stash in dynasty/keeper leagues, but there's a chance that he won't be placed right back into a starting role at the big-league level when he completes his rehab assignment. The former third overall pick had a rough 8.10 ERA and 1.75 WHIP with five walks and 16 strikeouts in 20 innings over his first five starts of the year with Texas before getting hurt.
