LOS ANGELES — Knuckleballer Steven Wright threw a complete-game shutout, and the Boston Red Sox rolled to a 9-0 rout of the Los Angeles Dodgers before an announced sellout crowd of 52,728 at Dodger Stadium on Friday night.

Wright (13-5) retired 18 of 19 batters before giving up a single to Yasmani Grandal to open the eighth inning. Wright finished with nine strikeouts and one walk and held the Dodgers to three hits.

Wright is the only major league pitcher to allow three runs or fewer in his 11 road starts this season, tying Rogers Clemens’ club mark set in 1988.

Mookie Betts, Sandy Leon and Travis Shaw homered for the Red Sox (60-48). Shaw’s solo shot was among the highlights of a five-run eighth for the Red Sox, which allowed them to blow the contest open. Boston outhit Los Angeles 10-3. Leon, who went 2-for-3, drove in four runs.

Dodgers starter Scott Kazmir allowed four runs on five hits with four walks and two strikeouts in 5 1/3 innings. Kazmir (9-5), who hadn’t issued a walk in his previous three starts, suffered his second straight loss after compiling a seven-game winning streak.

The Dodgers (60-49) dropped their third game in four contests.

Former Dodger Hanley Ramirez returned after a two-game absence after injuring his left wrist Tuesday night at the Seattle Mariners. Ramirez was 0-for-4 with a walk and two strikeouts.

A sacrifice fly by Leon scored Jackie Bradley Jr., who reached on a fielder’s choice and advanced to third on a base hit by Aaron Hill, for a 1-0 Boston lead in the second inning.

In the third, Betts led off with a solo home run to left for a 2-0 edge. It was his 23rd homer this season.

Leon crushed a two-run blast to left off Kazmir in the fourth for a 4-0 advantage. It was Leon’s fourth of the season.
