PHOENIX (AP) - Zack Greinke earned his major league-best 16th victory with six strong innings and the Arizona Diamondbacks beat Los Angeles 8-1 on Thursday to complete the first series sweep of the Dodgers this season.
Chris Iannetta and A.J. Pollock homered for the Diamondbacks, who matched their season-best seventh straight victory and pulled 3 1/2 games ahead of idle Colorado for the National League's top wild card spot.
The Dodgers, still with by far the best record in the majors (91-40), have lost a season-worst five in a row.
Greinke (16-6) allowed a run and four hits, striking out six and walking two, to improve to 13-1 in 16 home starts this season.
