Diamondbacks' Zac Gallen: Slated for sim game Tuesday

Gallen (hamstring) threw a 37-pitch bullpen Friday, and the right-hander is slated to throw a sim game Tuesday, Alex Weiner of ArizonaSports.com reports.

Gallen threw from a mound for the second time since landing on the injured list May 31 due to a right hamstring strain. It's another step in the right direction for the 28-year-old, who before the injury registered a 3.12 ERA and 1.14 WHIP over 57.2 innings.
