The Astros have informed Singleton that he isn't going to be on the major-league roster to begin the season, Matt Kawahara of the Houston Chronicle reports.

EDGE Analysis

Singleton struggled at the plate this spring, slashing .171/.239/.195 with no homers and 10 strikeouts over 46 at-bats. He had been in the running to back up Christian Walker at first base. With Singleton not slated to make the club, the door could be open for Zach Dezenzo to land an Opening Day roster spot.
