Zac Gallen has a 3-1 record with an ERA of 1.93 and 21 strikeouts in four career appearances against the Phillies in his career. Gallen is coming off his worst start of the season but I like him to bounce back here. The Diamondbacks are 7-2 in his last nine starts.

Diamondbacks are 7-1 in their last 8 against a team with a losing record.
Phillies are 3-8 in their last 11 against a team with a winning record. Ranger Suarez also was not been as sharp at home over the last season with a 4.68 ERA in his last 14 home games.
