As the season progresses, several High-A prospects are catching the eyes of fantasy baseball managers eager to find the next breakout stars. George Lombard Jr. of the Yankees is showing improved power with a 177 WRC+ and 39 stolen bases in his first pro season. Yophery Rodriguez, recently traded to the Red Sox, has a WRC+ of 146 and is demonstrating excellent plate discipline. The Guardians' Alfonsin Rosario has made a leap with a 163 WRC+ and five home runs, while Arjun Nimmala of the Blue Jays is impressing with consistent hitting and raw power. Ryan Waldschmidt of the Diamondbacks is also standing out, boasting a 185 WRC+ as he progresses through the minors. Observing these risers can be key for dynasty leagues, especially as they climb through the ranks and potentially become future stars.
