Muncy, Vargas exit game after head-on collision at first base

PHOENIX -- Dodgers third baseman Max Muncy and D-backs first baseman Ildemaro Vargas both exited Arizona's walk-off 3-2 victory Thursday night at Chase Field after a collision at first base in the top of the fifth inning.

Muncy grounded a ball to first base, where Vargas was able to field it from behind the bag. From opposite sides of the bag, Vargas and Muncy were racing to get there when both collided head on.

Muncy beat Vargas to the bag for a base hit, but both were down for several minutes as their respective training staffs checked on them. They were able to stand under their own power, but both came out of the game.

Per the Dodgers, Muncy exited due to shortness of breath and was being evaluated for a concussion. The club expressed optimism after the loss that Muncy may have avoided a concussion, and while he is expected to be out of the lineup for its home series opener against the Angels Friday, hope remains that he will avoid a trip to the injured list.

The D-backs have shared no further updates on Vargas' condition.

Muncy was replaced by pinch-runner Santiago Espinal, who also took over at third base, and Vargas was replaced at first base by Pavin Smith.
