Overturned call at first gives D-backs inning-ending DP

WASHINGTON -- D-backs manager Kirk Gibson won a replay challenge of a call at first in the first inning on Thursday at Nationals Park.

With one out and runners at first and second, Washington's Adam LaRoche hit a grounder to second baseman Aaron Hill, who flipped to shortstop Cliff Pennington for the force out. Pennington then fired to first to attempt to turn the double play.

First-base umpire Bob Davidson called LaRoche safe at first and Gibson challenged the call.

After a brief review, the call was overturned and LaRoche was called out to end the inning.
