UNDATED (AP) — Los Angeles Dodgers ace Clayton Kershaw looked pretty good in his first outing since he strained a back muscle in the team's season opener in Australia.

The reigning National League Cy Young Award winner struck out nine over seven shutout innings as the Dodgers whipped Washington 8-3. Kershaw gave up nine hits and had to work out of a one-out, bases-loaded situation in the sixth inning to keep the Nationals scoreless.

Drew Butera's three-run homer put the Dodgers ahead 8-0 in the eighth inning. Hanley Ramirez also homered and had two RBIs as the Dodgers snapped a two-game skid.

Also in the majors:

— Grady Sizemore's third hit of the night was a walkoff single in the 12th inning of Boston's 4-3 decision over Cincinnati. Sizemore and Mike Napoli each had two RBIs for the Red Sox.

— The New York Yankees pulled out a 4-3 win over the Angels on Brian Roberts' tiebreaking solo homer with two out in the ninth. Roberts had two RBIs as the Yankees won for only the second time in seven games.

— Baltimore and Tampa Bay sat through a 19-minute power outage delay just before Ryan Flaherty and Nick Markakis (mahr-KAY'-kihs) both drove in a run in the top of the eighth to lift the Orioles past the Rays 5-3. Evan Longoria hit a two-run homer for the Rays, who loaded bases with one out in the ninth but failed to score against Tommy Hunter.

— Carlos Gonzalez was 5-for-5 with three RBIs and two runs scored as Colorado walloped Texas 12-1. Nolan Arenado lined an RBI double in the seventh to run his hitting streak to 26 games, one off the Rockies record set by Michael Cuddyer (kuh-DY'-ur) last year.

— Justin Smoak had two hits, three RBIs and two runs scored in Seattle's 8-3 pounding of Oakland. Rookie Roenis Elias (roh-EH'-nihs eh-LEE'-uhs) is 3-2 with a 3.27 ERA after allowing three runs over 6 1/3 innings of the Mariners' ninth victory in 11 games since an eight-game skid.
