Tulowitzki went 1-for-3, with the hit being a bloop double, and played five innings but didn't have a defensive chance. Giambi went 1-for-3 with an RBI groundout as the designated hitter. Both will be off on Saturday and will play on Sunday.
Manager Jim Tracy said the comeback of Tulowitzki is linked to the Rockies' approach with Josh Rutledge, a prospect who was playing shortstop in Tulowitzki's absence but has been nursing a sore left quadriceps all week. Rutledge was used as a pinch-hitter on Friday, and will be used sparingly until the Rockies are sure he is healthy.
When Tulowitzki returns, the Rockies want to move Rutledge to second base and see how he meshes with Tulowitzki, a two-time National League All-Star.
"I would love to see the dynamic of what it looks like with those two guys in the middle of our field," Tracy said. "To do so, we've got to have them both healthy.
"We want Josh Rutledge a lot more than just a percentage of himself. I don't want to push a quad because you're one chopped ball and a hard sprint to first base away from really pulling it badly -- and that's a month when that happens."
