I've never seen anything quite like it.
Adam Jones' inside-the-park home run in the fourth inning today was a catchable ball - granted, it would've been a highlight reel catch - but even had it not been caught, it should've been a double, a triple at best. Nyjer Morgan missed the catch, the ball hit off his glove and dropped behind him.
He didn't turn around. He spiked his glove on the warning track as Jones circled the bases. Until we hear any different, it seems likely that Morgan thought the ball had dropped over the fence, and thinking he should've caught it, he flashed some emotion.
And it cost him, and the Nats, a run.
I don't mind players showing emotion on the field, but this was a case of temporary blindness. Unless you actually see the ball clear the wall, keep your glove on your hand and look over your shoulder.
I'm a big fan of Morgan's, but this won't be one of his more memorable moments.
