Junior quarterback Joel Blumenthal threw for four touchdowns and ran for another. He completed 15 of his 17 passes before leaving late in the third with the game well in hand.
“I liked what we were able to do offensively,” Gower said. “We were able to get some younger kids good playing time and everybody gave good effort.”
Both of Blumenthal's final two touchdown passes — one to Dinkines and another to Grayson Johnson — came on fourth down.
Down 13-0 late in the first quarter, Southeast looked like it had a chance to climb back in the game, going on a 14-play drive that lasted nearly seven minutes.
But on fourth-and-1, Deer Creek's defense pinned Southeast quarterback Micah Hunter with a five-yard loss to get the ball back and two plays later Dinkines scored to put the Antlers up 20-0.
About the only negative for the Antlers was the penalties, as Deer Creek was flagged 14 times for 129 yards.
Deer Creek (4-1) hosts El Reno next Friday. Southeast (2-3) plays at Carl Albert.
