Ryan Gordan blocked a potential game-tying field goal late in the fourth quarter as the host Arroyo High football team knocked Alameda out of playoff contention with a 17-14 victory on Saturday in a West Alameda County Conference-Shoreline Division game.
The Hornets needed a win to become eligible for the North Coast Section Division II playoffs.
With the game tied at 14-14, Carlos Jimenez capped an 11-play, 47-yard drive with a 37-yard field goal to give Arroyo (6-4, 4-1 WACC-Shoreline) the lead with 2:10 remaining.
Backup quarterback Elijah Hernandez marched the Hornets (3-7, 1-4) down to the Arroyo 5-yard line, William Upp was sent in to attempt a 22-yard attempt. Gordan broke through the line and got a hand on the ball to preserve the Dons' win.
Hernandez rallied the Hornets from a 14-6 deficit in the fourth quarter, scoring a 1-yard keeper, and then hit Keelan Doss for the two-point conversion with 6:06 left.
Chris Harrison ran for 108 yards and a touchdown for Arroyo.
