Falter is scheduled to start Wednesday's game against the Diamondbacks in Arizona.
Falter will be making his second straight turn through the rotation while the Phillies remain without Zack Wheeler (forearm), who was placed on the injured list last week. After striking out six and allowing three earned runs over six innings en route to earning the win his last time out Friday against the Pirates, Falter takes a 4.41 ERA and 1.24 WHIP into Wednesday's contest.
