ST. LOUIS -- Center fielder Colby Rasmus underwent an ultrasound procedure on Monday and was absent from the Cardinals' lineup for a second straight game with abdominal discomfort. Jon Jay started in center and batted second against the Phillies on Monday.
Rasmus said the injury occurred while working out during St. Louis' off-day on May 9, then aggravated it when he collided with the outfield wall while trying to rob a home run in Saturday's 7-3 loss in Cincinnati.
"Yesterday was probably the worst it's felt after doing that, but today it already feels better," he said.
Rasmus met with team physician John Ellena prior to Monday's game with the Phillies. He shagged fly balls, but did not participate in batting practice on the field.
