Mariano Rivera vowed to pitch again yesterday, and though most doctors believe the Yankees closer will be out until next season, Brewers starter Yovani Gallardo has proven Rivera may not have to wait that long.

Gallardo tore his right ACL during a start on May 1, 2008 and was back on the mound for the Brewers on Sept. 24 of the same season, giving up one run in four innings and striking out seven. He was less effective when he started the first game of the postseason that year, but has been solid — and healthy — ever since.

"It's going to be a tough four-and-a-half or five months," Gallardo said from San Francisco last night, where the Brewers faced the Giants. "You have to have a lot of patience after the surgery, waiting for your strength and range of motion to come back."
