The Arizona Diamondbacks will put their first-place status in the National League West on the line Wednesday night when they wrap up a three-game series against the San Francisco Giants. The Diamondbacks (72-60) have come up short in two low-scoring affairs, 2-0 and 1-0, in the first two games of the series to drop into a tie with the Colorado Rockies (72-60) atop the West. Arizona has been atop the division or tied for the top spot every day since Aug. 7.
