Washington Nationals right fielder Bryce Harper had never homered at Wrigley Field heading into Tuesday's game, which might explain his comical initial reaction to a solo shot he hit to left field.

With the Nats trailing, 1-0, in the seventh, Harper hit what he thought was a routine fly ball to left field, tossing his bat to the side as he shook his head in disgust while jogging up the first-base line.

Harper was then surprised to see the ball take off in the Chicago wind and land in the left-field bleachers.

After he crosses the plate, you can see the slugger mouth the word "Wow!" to Ryan Zimmerman as he congratulates him.
