Beltran, as he was on Monday, is available to pinch-hit on Tuesday, and the Cardinals are optimistic that the right fielder will rejoin their lineup during the team's next series.
According to Matheny, Beltran is not dealing with much swelling in his knee, which he had surgery on prior to the 2010 season. The issue is simply soreness, something that the Cardinals anticipated Beltran likely would deal with at some point during the year.
The Cardinals' medical staff was scheduled to reexamine the knee on Tuesday, but didn't expect to find any serious issues.
Said Matheny: "They're all pretty confident that we're on the front of it here."
