Gatts (shoulder) participated in catching drills Saturday, but has not yet resumed throwing, Jake Kaplan of the Houston Chronicle reports.

EDGE Analysis

Soreness popped up in Gattis' right shoulder, preventing him from taking part in baseball activities. Next up, the Astros will get him throwing and taking at bats. Houston starts playing in games Feb. 25, so Gattis will have several days to get up to speed. The Astros view him as the backup catcher, who will serve as designated hitter from time to time.
