Dodgers 6, Reds 3: Andre Ethier homered and ripped a three-run triple to back another strong start by Zack Greinke as host Los Angeles topped Cincinnati for the second straight night.

Greinke (8-1) allowed three runs in 7 2/3 innings while matching a season high with 11 strikeouts against zero walks to improve to 4-0 at home. Hanley Ramirez and Chone Figgins each had RBI singles for the Dodgers, who tied a season high with their third straight win.

Reds starter Alfredo Simon (6-3) was reached for five runs on five hits and four walks in 3 2/3 innings while losing for the first time in six road decisions. Devin Mesoraco hit a two-run homer to chase Greinke in the eighth and Roger Bernadina delivered a run-scoring single in the fifth as Cincinnati dropped its fourth in a row for the first time this year.

Ethier hit the first pitch he saw from Simon in the bottom of the second over the wall in right-center for his first home run since April 19. Following two singles and a walk in the fourth, Ethier lined a shot into the corner in right to clear the bases and make it 4-0.

Greinke retired the side in order in the first, third and sixth innings and struck out Bernadina with runners on the corners to end the seventh to preserve a 5-1 advantage. Mesoraco slugged a 3-2 offering from Greinke out to left to make it 6-3 in the eighth, but J.P. Howell came on to get the final out of the frame and Kenley Jansen cruised through the ninth for his 16th save.
