Paul Goldschmidt delivered a go-ahead triple in the bottom of the eighth as the Diamondbacks beat the Giants 3-1 on Friday to clinch the NL West. Goldschmidt also walked and scored Arizona's first run against Matt Cain in the seventh. His triple came after Cain was removed from the game, though both runs were charged to Cain. It was his first in 43 major league games, but it gave him 26 RBI in 142 at-bats. He deserves to be Arizona's primary first baseman in the postseason.
