Josh Garufi led off with a double to left and scored on a one-out double to left-center by Noah Sheehan.
Windsor had the tying run on second base with two outs in the seventh, but Bitzer got Jake Conroy to ground out to short to end it.
Third baseman Garufi also started a pair of 5-4-3 double plays for the Jackets.
“In a close game where runs are hard to come by, to get a double play is a big pick up,” Hughes said. “To do that twice was huge. Garufi played extremely well at third.”
Against Seton, the Yellowjackets were held hitless by David George through four innings and trailed, 1-0. OHS broke through for four runs in the fifth inning.
Brock Eichler led off with a walk and scored on a double to right by Collin Neer. Conor Tavarone followed with an infield hit and Garufi walked to load the bases. Brunetta then hit a three-run double off the fence in left-center to give OHS a 4-1 lead.
Winning pitcher Kevin Smith struck out 11, walked six and allowed four hits innings through 6 2/3 innings.
Smith suffered a concussion in gym class and hadn’t played or practiced for about a week-and-a-half, Hughes said.
“He had a good breaking ball and a good fastball,” Hughes said. “He pitched out of some big innings, too. They had chances every inning, but he was able to make pitches. It was an impressive outing.”
Neil McCormack hit a two-out, two-run double in the seventh inning that pulled the Saints to 4-3, but Sheehan relieved Smith and struck out the final batter to get the save.
The Yellowjackets will travel to Chenango Valley at 1 p.m. today.
