Yovani Gallardo's working on a shutout, with his Brewers up 2-0 through the top of the seventh inning.

Does Gallardo have a good shot at finishing the whitewash?

Gallardo has thrown only three shutouts in his 116 career starts (including a Division Series start against the Phillies, three years ago). Two of those shutouts came in 2010, and the other came this season ... nearly six months ago, against the Braves. In that game, Gallardo gave up only two hits -- same as this one, so far -- but struck out only two Braves, compared to six Diamondbacks (so far) today.

He's thrown 87 pitches in his seven innings, or roughly 12 per inning. If he's able to maintain that pace, he'll need around 112 pitches to finish, and Gallardo was allowed to throw at least 110 pitches in 10 of his 33 starts this season.

So if he keeps pitching like this, the math's in his favor. That said, he did give up a couple of loud outs in the seventh inning, and the Brewers have two outstanding relief pitchers available in the late innings. Gallardo might get a shot at the shutout, but manager Ron Roenicke will probably have his starter on a short leash.
