Musgrove was scratched from his scheduled start for Triple-A Fresno on Saturday, the Houston Chronicle reports.
It would seem Musgrove is the Astros' insurance policy in case Doug Fister, whose wife is expecting the couple's first child this weekend, is unable to take Monday's turn. Although Musgrove hasn't been nearly as dominant since his promotion from Double-A Corpus Christi, his impeccable control has translated to the higher level (seven walks in 59 innings), and the overall numbers with Fresno are strong. He's given up just two runs on 12 hits while striking out 16 in his last two starts for Fresno (14 innings).
