Berkman has surgery on left knee

Lance Berkman is expected to miss two to four weeks after having

knee surgery to remove loose cartilage from his left knee.

Astros manager Brad Mills said that the surgery on Saturday

showed there was no damage to the meniscus or ligaments. The

timetable for Berkman’s recovery puts him in jeopardy of missing

Opening Day.

Mills said that the team would not move Carlos Lee or any other

outfielder to first if Berkman is out for the start of the

season.

Berkman’s backup, Geoff Blum, went 1 for 4 with an RBI for an

Astros split squad that topped the Nationals 8-7 on Saturday. Chris

Shelton and Jeff Keppinger could also see time at first.
