The Cardinals are holding outfielder Peter Bourjos out of action for at least one more day with tightness in his right leg, reports MLB.com's Jenifer Langosch. He alerted the team to the problem after Sunday's game and he has not played since.

"They're testing him out," said manager Mike Matheny. "He has good strength, which is always the sign that we're not looking at anything major. But it was a little tender. We're just staying away from pushing him."

Bourjos, 26, has battled hamstring problems over the years, including missing more than a month with a strain early last year. As speed and defense-first player, any kind of leg problem is a big deal. Bourjos' value will take a huge hit if he loses a step due to injury.
