Zack Greinke watched second baseman Howie Kendrick glove Wil Myers' line drive to end the second inning with the bases loaded, and then hopped off the mound in joy. While it was a rare show of emotion, Greinke did what he does best - beat NL West foes. Greinke held the San Diego Padres to four hits in seven innings, and Carl Crawford homered to help the Los Angeles Dodgers to a 3-0 victory Friday night. It gave a couple guys days off out there.'' Greinke (3-0) improved to 21-1 with a 1.88 ERA in 31 games against division opponents since joining the Dodgers as a free agent before the 2013 season.
