Washington Nationals shortstop prospectSeaver King is currently on the 7-day IL at Triple-A Rochester, but he still holds a solid stash upside in deeper leagues. His combined numbers this season at Double-A Harrisburg and Rochester are a .306 batting average, 10 homers, and 51 RBI, along with 50 runs and nine stolen bases. He has demonstrated five-tool ability during his time healthy this season in the minors, but faces a logjam in the MLB infield.He is blocked byCJ Abrams at shortstop in the big leagues and byNasim Nunez at second base. King seems to have the tools to be a big-league contributor, but 2027 might be the year he becomes a fantasy contributor as he continues to get healthy and develop. The 23-year-old could be a name to watch in fantasy leagues, but it might be a surprise if his Washington Nationals future comes as early as the 2026 season.

Colorado Rockiesfirst base/outfield prospect Charlie Condon appears primed to make a difference in the second half of the season at the big-league level. Up to this point this season, Condon has proven to be a quality bat at Triple-A Albuquerque, mixing elite hitting skills with a knack for power. At Albuquerque, Condon is hitting .289 with 20 homers and 60 RBI to go with 75 runs scored. In July, Condon is hitting .310 after hitting .337 in June. The No. 2 overall prospect in the Rockies' system is starting to rake for Albuquerque, and it might not be long before the former No. 3 overall pick out of the University of Georgia makes his big league debut. It would be hard for the Rockies to keep a bat like Condon's in the minors, and now is the time to add Condon to fantasy teams. His high-upside bat should pay off big time in the second half, making him a must-stash candidate.

Miami Marlins starting pitching prospect Karson Milbrandt is making a strong case for a promotion to the big league club despite two rough starts at Triple-A Jacksonville in his latest outings. Milbrandt has pitched well at two levels this year, going 4-1 at Double-A Pensacola with a 1.34 ERA and 70 strikeouts in 47 innings. Then he has gone 0-2 with a 5.48 ERA and 20 strikeouts in 23.0 innings pitched for Jacksonville. The Jacksonville numbers are slightly concerning for the 22-year-old right-hander, especially the nine earned runs he has given up in his last two starts. The numbers at Double-A and his prospect pedigree as the Marlins No. 4 overall prospect make him a desirable waiver-wire option as he waits for his shot to prove himself in Miami. With Eury Perez and Janson Junk healthy again, the Marlins rotation is at capacity right now, but a good stretch in the second half at Jacksonville could give Milbrandt a chance to show off his skills in Miami.

Minnesota Twins starting pitcher Taj Bradley finished the first half by holding the Angels to two runs over seven innings Sunday. He is 3-0 in July with a 1.89 ERA, 0.95 WHIP, and 27 strikeouts in 19 innings, pushing his season line to 9-3 with a 3.59 ERA and 118 strikeouts across 102 2/3 frames. Bradley's cutter and splitter have done the heavy lifting, generating 39.0% and 38.7% whiff rates. The fastball is still getting hit hard, and 15 home runs plus 40 walks leave some blowup risk. That matters less after three straight wins with at least six strikeouts in each. Bradley is now 77% rostered on Yahoo, so he may already be gone in most leagues. Where he remains available, he should be treated as a must-add rather than a streamer.
