Aidan O'Connell threw for four touchdowns in the first half Thursday night and the Las Vegas Raiders set a franchise record for most points in a game in a 63-21 evisceration of the Los Angeles Chargers in Las Vegas.

O'Connell completed 20 of 34 passes for 248 yards as Las Vegas improved to 6-8, keeping its slim AFC wild-card hopes alive. Los Angeles fell to 5-9 with its fifth loss in six games, clinching a losing season in a year when some picked it to win the Super Bowl.

It was a complete 180-degree turn for the Raiders, who were shut out on Sunday in a dreary 3-0 loss at home to Minnesota. But they roared out to a 42-0 halftime lead Thursday and never looked back, dropping their AFC West rivals to last place in the division.

Zamir White initiated scoring at the 8:10 mark of the first quarter with a 1-yard run, then O'Connell went to work. He found Tre Tucker for a 30-yard touchdown pass with 4:41 left, then made it 21-0 with a 22-yard connection to Jakobi Meyers. Both came right after Chargers turnovers.

Los Angeles put the game away in the second quarter. O'Connell cashed in a fumbled punt two plays later, hitting Michael Mayer for an 11-yard touchdown pass with 9:15 remaining.

Brandon Bolden ran 26 yards for a score at the 3:50 mark, and O'Connell hooked up with Tucker for a 20-yard touchdown 31 seconds before the half ended.

The Raiders made it 49-0 on their first possession of the second half as Meyers flipped a 3-yard scoring strike to Davante Adams. Their defense got into the act for their last two touchdowns as John Jenkins returned a fumble 44 yards and Jack Jones lugged an interception 16 yards.

Chargers quarterback Easton Stick, who made his first start in place of Justin Herbert (finger), hit on 23 of 32 attempts for 257 yards with three second-half touchdowns, including a 79-yard strike to Joshua Palmer.
