In the top of the 4th inning of the Nationals-Marlins game, Nationals batter Jayson Werth hit a 0-1 fastball from Marlins pitcher Josh Johnson to the top of the right field wall. The ball bounced back onto the field of play, as 1B Umpire D.J. Reyburn (70) ruled a home run. After instant replay review, the call stood. Did the ball indeed hit the metal "pipe" out of play or did it hit the top of the wall?
