Tests show no concussion for Holliday in collision

Cardinals left fielder runs into Dodgers' Ramirez on pickoff play at second

ST. LOUIS -- Tests for a possible concussion came back negative on Cardinals left fielder Matt Holliday, who exited Saturday's 4-2 win in the fifth inning, four innings after he collided with Dodgers shortstop Hanley Ramirez while scampering back to second base.

Holliday drove home two runs with a first-inning single and advanced to second when Carl Crawford bobbled the ball in left field. Before throwing a pitch to the next batter, Matt Adams, Dodgers starter Zack Greinke made a pickoff throw to second. 

As Holliday slid back to the bag, he made contact with Ramirez, who fell into Holliday's head. The Cardinals' left fielder was slow to get back on his feet and consulted with manager Mike Matheny and a team athletic trainer for several minutes before remaining in the game. 

He initially notified the training staff of some headaches and dizziness. Holliday responded well to a few quick tests by the trainers when he came back to the dugout, which is why he remained in the game. When his responses deteriorated a few innings later, the Cardinals then made the decision to take him out.

"That's stuff we pay attention to," said manager Mike Matheny, well-versed in the risk of concussions. "We're going to err on the side of caution. He came in and was just off a little bit. I understand that explanation, that description. It's better to go ahead and find out what we're dealing with."

Holliday, who declined a request to speak with the media, is listed as day to day. Peter Bourjos pinch-hit for him in the fifth and remained in the game to play center. Jon Jay moved over to left.
