Against the Astros on Wednesday, Cardinals outfielder Matt Holliday suffered a quad injury that caused him to miss Thursday's game.
Holliday, who was used as the team's designated hitter against the Royals this weekend, aggravated the injury and left today's game in the fifth inning after beating out a potential double-play ball.
Per Matthew Leach of MLB.com, the Cardinals said the move to take Holliday out of the game was "precautionary."
The Cardinals begin a three-game series in San Diego tomorrow.
On the season, Holliday is hitting .349 with six home runs, 31 runs batted in and 31 runs scored although he is only 3-for-26 (.115) in his past eight games played.
