Astros first baseman Lance Berkman plans to return to the lineup on Tuesday against the Marlins. Berkman went 3-for-4 with a homer and a double in his second of two rehab games on Sunday at Triple-A Round Rock. He underwent arthroscopic surgery on his left knee on March 13 and hasn't appeared in any games for the Astros this year. "I've already talked to Brad Mills and tried to call [general manager] Ed Wade," Berkman told MLB.com. "[Mills] asked me if I could go Tuesday, and I said, 'Absolutely.' He said is this the type of thing where we're going to have to nurse you along, and I said, 'No, you can run me out there for about 10 or 15 games and see what happens.' I anticipate being in the lineup on Tuesday and not coming out of it until the end of the year."
