The RubberDucks blew the game open with a five-run sixth inning. Eric Haase hit a long homer over the Dunkin’ Donuts video board to make it 3-0, then two more runs scored on Moncada’s second error. Jordan Smith followed with an RBI single and Nellie Rodriguez hit a sacrifice fly to make it 7-0.

Akron starter Rob Kaminsky (W, 6-7) went five scoreless innings and allowed just three hits and two walks. He struck out five.

The Sea Dogs scored both of their runs in the sixth inning off of Robbie Aviles. Cody Decker hit a bases-loaded grounder to third that was misplayed by Joe Sever. Jake Romanski then hit into a 5-4-3 double play, but Nate Freiman scored to make it a 7-2 game.
