Worth noting

• Manager Walt Weiss did not rule out using right-handed-hitting center fielder Drew Stubbs as a leadoff man, although the plan is to use him below the middle of the order. Stubbs has a tendency to strike out and has a low career on-base percentage, but the potential combination of power and speed could serve the Rockies well at the top of the order on occasion.

"He's done it before and there's an element to his game -- obviously, the speed element -- that's that option appealing," Weiss said. "But I want to make sure a guy doesn't doesn't have to revamp his whole game because we're moving him to a spot that doesn't suit him.

"I'm not getting too hung up on the batting order right now. That stuff will play out. We'll figure that out. There's some kind of tweak to the lineup just about on a daily basis."

• Righty reliever Wilton Lopez, hoping for important late innings, is back throwing after being slowed over the weekend by a stiff neck.

• Sometime around the middle of March, Weiss said the Rockies will have a staff meeting to determine protocol for using instant replay challenges. They'll determine the rotating personnel who will be looking at replays to see which plays should be challenged, and how suggestions will be relayed to the dugout.
