From Rotoworld:

Morgan Ensberg said his slow start last season was due in part to an elbow injury. This season, he's healthy, and manager Phil Garner plans to use him in the meat of the order.
"He needs to hit doubles and home runs, because that's the way you drive in runs," Garner said. "We need him to be a big run producer, and he's swinging the bat good this spring." It's not inconceivable that Ensberg could even open the season as Houston's cleanup hitter behind Jeff Bagwell with Lance Berkman injured.

The cleanup spot? Maybe. I like Lane there right now. But we'll see.
