SAN DIEGO (AP) — Philip Rivers threw for one score and reached the 4,000-yard mark for the fourth straight season, Ryan Mathews ran for two scores and hit 1,000 yards rushing, and the San Diego Chargers kept their slim postseason hopes alive with a 34-14 victory against the playoff-bound Baltimore Ravens on Sunday night.

The Chargers (7-7) neutralized Baltimore's normally ferocious defense, which got Ray Lewis back after a four-game injury absence, and scored on six of their first seven possessions. San Diego is tied with Oakland, a game behind Denver with two to play. San Diego has won three straight after a six-game losing streak.

The Ravens (10-4) had their four-game winning streak snapped, but clinched a playoff berth earlier in the day thanks to losses by the New York Jets, Oakland and Tennessee.

Baltimore's Joe Flacco was sacked five times - three by former Ravens linebacker Antwan Barnes - and intercepted twice.
