Allen Webster pitched into the sixth inning to win in his Arizona debut, Paul Goldschmidt had two hits and an RBI and the Diamondbacks beat the San Francisco Giants 4-2 on Saturday. Webster, who spent the first two months in the minors after starting 11 games for Boston last season, was called up before the game and didn't allow a hit until Joe Panik's double with one out in the sixth. The Arizona right-hander gave up two runs and two hits with two strikeouts and three walks.
