The Evangels also grabbed a quick lead in the nightcap on an RBI single by Jerry McNew that plated pinch runner Rhett Barber.
It stayed 1-0 through three innings when the Stars broke through with a three-run fourth inning that was capped by a two-run single from Skyler Bean.
Shaun Corso then broke the game open with a three-run homer in a four-run fifth inning and another RBI single by Bean in the seventh tacked on another run for the Stars.
Ben Donnell allowed five runs in his four innings of work, while Roberto Delgado got the win for the Stars after giving up one run and striking out three in 4 2/3 innings.
