St. Louis Cardinals left fielder Matt Holliday has been placed on the 15-day disabled list with a strained right quadriceps, according to USA Today. He suffered the injury -- an aggravation of his previous quad ailment -- in Wednesday's 1-0 loss to the Cincinnati Reds. Holliday was already on the disabled list from June 9 to July 12 due to a previous injury to the same muscle, missing 31 games of action. There is no word yet on how much time Holliday will miss with this latest issue, but St. Louis acquired outfielder Brandon Moss from the Cleveland Indians on Thursday. Holliday, who is hitting .290 with four home runs and 31 RBI, has played in 63 of the Cardinals' 111 games this season. This year will be the first time he's played in fewer than 120 games in his 12-year career.
