Raiders improve to 4-1 with a 34-31 victory over the Chargers

Derek Carr threw a go-ahead 21-yard touchdown pass to Michael Crabtree on a fourth-and-two gamble and added another TD pass to Amari Cooper to lead the Oakland Raiders to a 34-31 victory over the mistake-prone San Diego Chargers.

San Diego (1-4) committed four turnovers and then botched the hold on a potential tying field goal. Rookie Drew Kaser couldn’t hold the snap on what would have been a 36-yard field goal attempt.

The Raiders (4-1) took over with two minutes left and ran out most of the clock to get a third straight win for the first time in five years and hand San Diego its 10th straight division loss.

Oakland took the lead on a bold call late in the third quarter. Facing a fourth and two at the 21 late in the third quarter trailing by five, coach Jack Del Rio once again trusted his offense to make a big play and it paid off.

Carr found Crabtree deep down the left side for the touchdown that put the Raiders up 25-24. A 2-point conversion pass to Cooper gave Oakland a three-point lead and Jamize Olawale added a one-yard run that made it 34-24 on a drive set up by Kaser’s 16-yard punt.

Carr threw for 317 yards, including a 64-yard pass earlier in the third quarter that gave Cooper his first touchdown of the season. Cooper had six catches for a career-high 138 yards.

Philip Rivers threw for 365 yards and four scores for the Chargers, who were once again done in by their own mistakes. San Diego has three losses already this season in games it led at the two-minute warning.
