Musgrove will join the Astros' rotation on Sunday with Lance McCullers landing on the DL with elbow discomfort, the Houston Chronicle's Angel Verdejo reports.
He is likely already owned in deeper/serious leagues after making a very impressive debut Tuesday, striking out eight over 4.1 one-hit innings of relief, but if he is still available on waivers, now is the time to grab him in mid-sized leagues. Musgrove is one of the Astros' top prospects and a top-100 prospect in the game. He uses plus-plus control and mid-90s fastball to get ahead of hitters early, and can rack up strikeouts while maintaining efficient pitch counts. McCullers is out indefinitely and Musgrove should get at least a handful of starts as long as he can keep his head above water.
