Padres-Diamondbacks Preview (Yahoo Sports)

Zack Greinke won't dig too deep to figure out exactly why he's throwing the ball better for the Arizona Diamondbacks. Looking to win a third straight start, Greinke tries to help the Diamondbacks avoid a fifth consecutive defeat Saturday night against the visiting San Diego Padres. Since giving up 11 runs in 10 innings of his first two starts, Greinke (5-3, 4.59 ERA) has yielded two or fewer in five of eight outings.
