WASHINGTON (AP) — Shohei Ohtani had three doubles to improve his major league-leading batting average to .371, rookie Landon Knack got his first victory and the Los Angeles Dodgers routed the Washington Nationals 11-2 on Wednesday night.

The Dodgers had a season-high 20 hits en route to their third straight victory, with Mookie Betts and Will Smith each having four hits and Andy Pages homering.

Nick Senzel homered for Washington. The Nationals didn’t have a baserunner after the second inning.

Ohtani went 3 for 6, hitting RBI doubles in the eighth and ninth innings. He leads the majors in slugging percentage (.695), OPS (1.128), extra-base hits (21) and doubles (14). He is hitting .429 during his nine-game hitting streak.

“His average exit velocity on balls he puts in play, he’s got to be in a category by himself,” Dodgers manager Dave Roberts said. “The ball just does different things when it comes off his bat.”
