There's an old saying in baseball that momentum starts and stops 60 feet, 6 inches from home plate.

That's where Yovani Gallardo will be standing Friday afternoon at the start of Game 5 of the National League Division Series at Miller Park, and it will be up to the Milwaukee Brewers ace to control an Arizona Diamondbacks offense that ran amok in the desert.

The Brewers never knew what hit them in Games 3 and 4 at Chase Field, falling behind early and never recovering. That leaves it to Gallardo, the Game 1 winner and a perfect 6-0 for his career against the Diamondbacks, to restore some normalcy in the early innings.

"It's very important," Gallardo said Thursday during a media session at Miller Park. "I think it's getting those first couple of innings out of the way, putting zeros up on the board. Who knows? That might be the whole difference in the ball game."
