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.
Other players the Cardinals want to call up for the season's final month have to be on the club's 40-man roster to be eligible for consideration. There are currently 39 players on that roster, meaning the Cardinals have the flexibility to add someone.
Top pitching prospect Shelby Miller is not on the team's 40-man roster. The Cardinals have been mum in recent days about whether Miller will be rewarded for his recent success by being among the group of pitchers summoned to the Majors.
