Ballston Spa responded with a drive of its own, which fullback Van Huyben capped with a five-yard touchdown run to tie the game at 7. But Denn scored on an 18-yard run in the second quarter, and Genzano added a 30-yard field goal before halftime to give Guilderland its nine-point lead.
Seager cut into that deficit with a 10-yard scoring run in the third quarter and put Ballston Spa ahead for good with a 16-yard run early in the fourth quarter.
The win keeps Ballston Spa tied with Bethlehem and Shenendehowa for second place in the Empire Division heading into Friday's game against Christian Brothers Academy (1-3).
"We certainly know how dangerous CBA is," said Bowen. "Between the athleticism of their quarterback (Andrew Vivian) and the obvious threat their tailback (Jack) Reilly is with his speed, we have some things to shore up defensively if we're going to win."
Meanwhile, Guilderland faces a tough final three weeks in its pursuit of a Section II, Class AA playoff berth. After a cross-divisional game with Niskayuna Friday, the Dutchmen face winless Albany before meeting unbeaten Saratoga Springs.
"Without question, we feel we are a team that can be competitive in the playoffs," said Penna.
First, Guilderland will have to get by a Niskayuna team that loves to throw the football.
"They run a true spread offense where they run every play from the shotgun (formation)," said Penna. "They throw the ball a lot, and they sprinkle in run plays. We'll have to mix up our coverages and try to do some things with our (defensive) formations to keep them off balance."
Blue Streaks get by Plainsmen
In other Class AA football action Friday, unbeaten Saratoga Springs hosts winless Albany, while Shenendehowa travels to Bethlehem with second place in the Empire Division on the line.
