Zac Gallen had a career-high 10 strikeouts over six scoreless innings, Christian Walker hit a two-run homer and the Arizona Diamondbacks beat the Colorado Rockies 4-0 in the first game of a doubleheader on Friday.
The 25-year-old Gallen (3-2) has been one of the NL's top pitchers for much of the season and saved one of his best outings for last, giving up five singles and walking two. He finishes the season with a 2.75 ERA over 12 starts and struck out 82 batters over 72 innings.
Yoan López and Stefan Crichton combined for a scoreless seventh to finish the shutout and further diminish the Rockies' already minuscule playoff chances.
