Video: Bryce Harper thinks he flied out, but homers

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.
