Last Friday, Aug. 15, was a big day in Major League Baseball. Teams around the league began calling up their top prospects over the weekend. However, Philadelphia Phillies top prospect Justin Crawford remained in Triple-A Lehigh Valley.
It's not just a coincidence that multiple highly touted prospects have joined the MLB ranks over the last few days, either. Aug. 15 marked the date that teams could promote prospects and have them maintain their rookie status for next season. To maintain rookie eligibility, position players must not be on the active roster for more than 45 days or accumulate more than 130 at-bats.
