Zack Greinke posted his career-high 18th victory, rookie sensation Corey Seager hit a two-run homer and Adrian Gonzalez doubled home two more to lead the Los Angeles Dodgers to a 6-2 victory over the Pittsburgh Pirates on Friday night. The only run the major league ERA leader gave up while he was in the game was a first-pitch homer by Neil Walker, who leads all NL second basemen with 14 home runs, 47 extra-base hits and 62 RBIs. The list includes Gaylord Perry, Randy Johnson, Pedro Martinez, Roger Clemens and Roy Halladay.
