The Summit SkyHawks kept taking the lead against San Gorgonio in their back-and-forth battle on Sept. 5 at the Spartans' field.
But just when it looked like the SkyHawks had a chance to clinch the game with a 26-20 advantage, the Spartans came back with two touchdowns in the final minute to pin a heartbreaking 32-26 loss on Summit.
San G. never led until scoring a TD on the game's final play, dropping Summit's non-league record to 2-1.
The defeat ruined terrific performances by running backs Darrin Thomas and Adrion Boyd. Thomas gained 181 yards in 15 carries and scored a pair of touchdowns, while Boyd accumulated 137 yards in 13 attempts and tallied one touchdown.
The first half was a defensive struggle, with the only touchdown coming on Marquis Roby's 22-yard pass to Joshua Hornsby.
After San G. tied the score at 6-6 in the third quarter, the SkyHawks went back in front on Boyd's 75-yard run around the left side at the start of the wild fourth period.
The Spartans forged a 14-14 tie, only to see Thomas put Summit ahead again, 20-14, with a 61-yard touchdown dash down the right sideline. But San G. responded with a TD to make it 20-20.
A 12-yard touchdown by Thomas put the SkyHawks on top once more, but it wouldn't last.
Hornsby caught 3 passes in the game for 93 yards and Michael Anderson had a 30-yard reception.
Summit's next game will be Friday, Sept. 13 at home against Barstow.
