The Rockies first baseman became the latest to forget how many outs there are in an inning.

Colorado Rockies first baseman Ben Paulsen suffered a moment Monday evening he will want to forget. 

During the top of fifth inning of the Rockies’ game against the Texas Rangers, Paulsen recorded the second out of the inning when Prince Fielder grounded to first, driving home Nick Martinez from third base. Paulsen mistakenly thought he had recorded the final out and started jogging into the dugout. That sudden lapse of judgement allowed speedy youngster Rougned Odor to score and give the Rangers two runs on a groundout.

Oops indeed.
