Bryce Harper has done everything in his career fast, and now that includes the first home run trot of his career.

Harper sprinted out of the batter’s box, and once the ball cleared the fence he never slowed his gait. Harper ran around the bases in about 18 seconds and kept sprinting all the way into the dugout, where Manager Davey Johnson met him with a high five and his teammates followed suit, patting him on the head and the backside.

Harper had been in an 0-for-11 rut before he smacked two hits Sunday in Cincinnati. He had only hit one home run all season, even in Class AAA. “I’ll get it going,” he said after the game. Tonight, he responded with the first home run of his career, the first of what promises to be many.

Rain began pouring in the fourth — which threatened to erase the homer from the record books.
