Manager Mike Matheny said to expect a "couple pitchers and a few position players" to join the Cardinals on Saturday, the first day that clubs can carry more than 25 players on their active rosters. One of those additions will be first baseman Lance Berkman, who wrapped up his Minor League rehab assignment with Triple-A Memphis on Thursday. Berkman singled in his first at-bat, but was taken out for a pinch-runner because of rain. The Cardinals did not want to risk Berkman doing any more damage to his already compromised knees. Berkman finished his rehab stint 3-for-17 with three walks and three strikeouts.
