OAKLAND -- McClymonds High's opportunistic defense propelled the Warriors to their third straight Oakland Section championship with a 38-13 win over Oakland Tech in Friday's Silver Bowl at Laney College.

Mack's defense scored three touchdowns and forced six turnovers to win its 21st straight game against Oakland Athletic League competition.

"It was probably one of the best displays of defense I've coached," Warriors coach Curtis McCauley said.

Mack (9-3) now hopes to have at least one more game to its season.

The section championship makes the Warriors eligible to be selected to the California Interscholastic Federation Division IV Northern regional championship game. Mack, which is ranked second in the division in Northern California by Cal-Hi Sports, will learn its fate Dec. 2.

The Warriors were passed over for a spot in the Division II state championship bowl game two years ago after going 12-0. They hope to be rewarded this time.

"It would mean the world to us," McCauley said. "We worked so hard to get here. Two years ago, we came up a little short. But our goals have always been to get back here."

Mack senior Kenyatta McGee Jackson rushed for 121 yards and two touchdowns and also scored on a 60-yard interception return in the fourth quarter.

"It just felt great to help my brothers out and do my part to help my team to a victory in the Silver Bowl," Jackson said.

The Warriors offense sputtered at times and was outgained 271-235 by Oakland Tech (8-4). But the defense more than made up for it.

On the Bulldogs' first possession, Mack's Shaqan Washington picked up a fumble and returned it 35 yards for a touchdown and 8-0 lead. Jackson's 1-yard touchdown run made it 14-0.

In the second quarter, Jackson helped deflect a pass that Lavon Washington intercepted and took 70 yards for another score.

"The offense wasn't really moving the ball, so the defense had to take control of the game," Lavon Washington said.

Oakland Tech trimmed the gap to 22-7 when Jeremiah Vernedoe scored on a 1-yard run. The Bulldogs were in position to score again, but Mack's Louis White intercepted another deflected pass at the goal line. It was the first of White's three interceptions on the day.

The game stayed 22-7 until the fourth quarter when Jackson scored on a 6-yard run. On the fourth play of Tech's next possession, he delivered his interception return for a score to put them game well out of reach at 38-7.

The Bulldogs scored with 2:30 left when they went on a 15-play drive, paced primarily by the running of quarterback James Lewis. He had 71 yards on five carries and scored on a 1-yard run.
