With runners at first and second, Julian Jarrard pulled a ball down the left-field line to score the game-winning run.

Down 2-0, the Warriors tied the game in the top of the seventh. After Michael Stefanic led off the inning with a single up the middle, Derek Rodigo doubled down the right field line, advancing Stefanic to third. Michael Pollex came up next and shot a ground ball to the first baseman’s right. The ball got past the Aliamus but was fielded by the second baseman Dalton Maxwell who tossed it to the pitcher covering the bag. Pollex, hustling down the line, was called safe at first as Stefanic scored and Rodigo advanced to third.
An attempted squeeze play worked out to the Warriors’ advantage when Luke Coffey bunted to the right of the mound for a single, bringing home Rodigo. Unfortunately, the Warriors were unable to plate any more runs in the inning.
