Game Preview: Giants vs. Diamondbacks

Diamondbacks:
The Diamondbacks have had many ups and downs over the last two weeks, and seem as likely to lose a game as to win one. Pitcher Micah Owings (5-2, 3.79) seems to be over his struggles from several weeks ago, and has posted to straight solid outings.

Giants:
The Giants again look to Tim Lincecum (2-2, 5.19) to turn in another solid start. He has struggle over the past month, but looked dominant in a start last week against the Padres. However, he lacked all control in that start, and managed to slide by with great stuff and a bit of luck.

Predictions:
As with last week, this game will be won or lost by Tim Lincecum. When he's on, he's as good as any starter in baseball, but when he's struggling, the Giants have little chance of winning.
