Bryce Harper might be playing home run H-O-R-S-E, hits dinger directly into bullpen bathroom

Bryce Harper has already hit some wonderful home runs this year. He got back at the Braves' boobirds with a dinger on Opening Day, he nearly hit one to the moon against the Marlins and he crushed a grand slam for his 100th career longball last week. 
So, to tie things up in the 10th inning of Sunday's Nationals-Phillies game, because hitting home runs has just become too easy for him, he decided to play some homer H-O-R-S-E -- launching a Statcast-best moonshot directly into the Phillies' bullpen bathroom:

Instead of taking on the challenge, Freddy Galvis chose to simply hit a walk-off double in the bottom half of the inning for a 3-2 win.
