The James Logan High football team is clicking on all cylinders, both offensively and defensively.

The Colts scored 41 first-half points en route to a 54-5 nonleague win over visiting Berkeley (0-4) on Friday night.

Logan (5-0) allowed just 173 yards of offense, and the first-team defense hasn't allowed a touchdown since a win over Reed-Sparks (Nev.) to open the season.

For the second week in a row, Logan quarterback Jeffery Prothro was on point. He was 6 of 7 passing for 145 yards and three touchdowns. He also rushed for 48 yards on six carries and two scores. All of his action came in the first half. Prothro hit Amalani Fukofuka three times for 92 yards and two touchdowns.

On the ground, Warren Miles Long had 111 yards on nine carries, including a 37-yard touchdown run. Teammate Damond Beasley had 86 yards on three carries, including an 81-yard TD run.

Newark Memorial 42, Irvington 0: The Cougars (3-1) were well-grounded in their win over the Vikings (1-3) in the Mission Valley Athletic League opener for both teams at Tak Fudenna Stadium.

Mark Morton gained 91 yards on 13 carries and scored three touchdowns, and Marty Leggett ran for 104 yards as Newark dominated.

It took just three plays for Newark to score its first touchdown when Morton ran 45 yards up the middle just 55 seconds into the game.

Three Irvington plays resulted in minus yardage, and the Cougars took over on the Vikings' 30-yard line. Newark took seven plays to score, with Morton plunging 2 yards for his second TD.

After an Irvington punt, the Cougars drove 43 yards in eight plays with Morton scoring on another 2-yard run with 39.4 seconds left in the first quarter.

Newark got its only score of the second quarter when quarterback Riley Pivin threw a 61-yard pass to Fred Tidwell.

Pivin also threw a 10-yard TD pass to Robert Ramirez in the third quarter.

Oak Grove-San Jose 27, McClymonds 20: Oak Grove needed a clutch third-and-long pass from backup quarterback Ray Cruz and big plays from receiver Will Ossai to hold off visiting McClymonds.

The host Eagles won against an opponent that desperately wanted -- but didn't get -- one more opportunity after scoring a touchdown with just under three minutes to play.

In the end, Oak Grove (3-0) completed a perfect nonleague schedule, although coach Jay Braun knows his team was far from perfect against McClymonds (1-3).

The Oakland school suited up only 24 players -- fewer than half of Oak Grove's roster -- yet had the Eagles in trouble in the closing minutes.

Keith Williams, who threw for 183 yards, cut Oak Grove's lead to 27-20 with 2:46 left when he scored on a 1-yard sneak and threw a two-point conversion pass to Jermaine McCann-Caluya.

McClymonds failed to recover the onside kick but looked as if it would get the ball back when Oak Grove faced third-and-16 at its 45.

Cruz, who came off the bench in the first half to throw a TD pass, had three defenders chasing him as he scrambled to his left. Just before he reached the sideline, he threw a pass to Ossai for a 16-yard gain that sucked the wind out of McClymonds' rally.

"I wish the game was still going right now, but, you know, what can I do?" Williams said.

Nick Bernardo took the opening kickoff and dashed 68 yards up the middle to the McClymonds 17. Two plays later, Chidobe Awuzie ran in from the 6 for a 7-0 lead.

Oak Grove patiently drove down field for another touchdown on its next possession. Dallas Misaalefua finished the 13-play series with an 8-yard scoring pass to Ossai, the only pass attempt for the Eagles in the quarter.

Northgate 55, Fremont 8: Jimmy Sharpe ran 63 yards for a touchdown and returned an interception 62 yards for another score within the first seven minutes of the game, and the host Broncos (4-1) wrapped up their nonleague season with a rout of overmatched Fremont.

Sharpe had 85 yards on four carries for Northgate, and Eric Haynes went for 82 yards and a touchdown on five carries.

On third-and-1 from the Northgate 37, Sharpe appeared to have been stopped by a crowd of Tigers defenders. But he broke through the clump before the whistle blew and outran the pursuit for the score.

Quarterback Joe Pelletier threw for 106 yards, with touchdowns of 15 and 20 yards to Brandon Lee.

Northgate ran for 331 yards.

Fremont (3-1), which had just 17 players in uniform, was held to 96 yards of total offense.

Encinal 34, Vallejo 8: It took three quarters for Encinal (3-2) to get much going, but a late offensive surge led the Jets to a win over visiting Vallejo (0-4).

Encinal's Corey Sails led the way, rushing for 131 yards on 18 carries, with three touchdowns. Sails also intercepted a pass.

Sails started the Jets' nonleague win with a 1-yard dive in the first quarter. Early in fourth quarter, Sails ran it in from 36 yards -- at that point, just the third play of the game over 20 yards.

Shortly after that, Encinal's Isaiah Hunter took an interception 36 yards for a touchdown. Hunter later scored on a 4-yard run to give the Jets a 27-0 lead.

Diablo Valley 44, Chabot 20: Quinn Kaehler completed 34 of 61 passes for 490 yards and five touchdowns as the host Vikings (1-3) led throughout this nonconference game.

The Vikings scored 21 points in the second quarter to take a 24-11 lead into halftime. After three quarters, DVC led 31-14.

Chabot (0-4) was led by quarterback Brandyn Eckhart. He rushed for 96 yards and a touchdown, and threw for 90 yards and another score.
