(AP) -- With Troy Tulowitzki on a tear, the Colorado Rockies appear to have moved past their recent offensive woes as they try for their first three-game winning streak in almost a month.

The All-Star shortstop, however, will now face a pitcher he's struggled against throughout his career.

Tulowitzki will try to stay hot Sunday and help the Rockies take three of four from the visiting San Francisco Giants, who send Barry Zito to the mound.
