Padres' Andres Munoz: Back at Double-A

Munoz is opening the year back at Double-A Amarillo, Mike Rosenbaum of MLB.com reports.

The best relief-pitching prospect in the minors, Munoz has the upside to someday be a top-five closer, thanks largely to a 103-mph fastball. However, he has plenty of work to do with his breaking ball and his command. Look for him to spend most of the year at Triple-A.
