Harper led off the fourth inning with a slow roller that second baseman Mark Ellis barehanded and flipped to first. The throw appeared to beat Harper and umpire Jeff Gosney called him out.
The 21-year-old Harper kept his head down, screaming his displeasure as he passed Gosney on his way to the third-base dugout. Gosney threw out Harper, who didn’t seem to initially realize he’d been ejected.
Nationals manager Matt Williams said he asked third base umpire C.B. Bucknor whether they could wait until the end of the inning before Harper had to leave the dugout. Williams said the crew wanted Harper to go immediately.
The game was briefly delayed while Harper gathered his belongings and walked to the visiting clubhouse beyond the left-field wall.
