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.
