Defense came through on the final play Saturday for the East Thunderbirds, who sacked West's quarterback on a point-after conversion run in overtime to captured the Cook Inlet Conference championship with a 13-12 overtime victory at Dimond Alumni Field.
The score was tied 6-6 after regulation and both teams scored touchdowns in OT.
East got the ball first in the extra period and scored on Tina Dunbar's run up the middle. Dunbar added a one-point conversion run to make it 13-6.
West answered with Dani Levine's 10-yard pass to Alexandria Rojas but couldn't convert its point-after attempt.
"We called time, and went for two (points) instead of one on the PAT and we didn't get it. They sacked the quarterback," West coach Travis Cantrell said.
The game was the rubber match for the two teams, which split during the regular season, with West taking the first game 12-0 and East winning the second game 20-0.
"It was a very, very good game," Cantrell said. "Good speed, good defensive play. To go into overtime tied 6-6 is pretty wild."
East, which downed regular-season champion Dimond 12-0 in a semifinal game, finished the season with an 11-6 record.
West, which got an 88-yard touchdown run from Anna Sophia Roberts during regulation, finished 11-6. Levine completed 10 of 20 passes for 275 yards to spark the Eagles.
