I guess his HR wasn't real after all. He's picking up the ways of the Pirates.
By the end of the season, they'll have an entire catalog of follies. The two balls not caught at the pitchers mound. Craig. Now Hayes.
What amazes me is the attention to detail that someone actually kept an eye on him as he rounded the bases.
What happened? Did Hayes fail to touch one of the bases as he ran them?
He missed 1B.

How is that possible? He's a finely tuned athlete who's in control of his body's movements. He's not a butterfly.
He was hustling for extra bases at that point before realizing the ball struck the foul pole. But he should have realized it and gone back when he saw it was a HR.
How is it possible for a player to miss a base? They're not postage stamped-sized, and THEY'RE STATIONARY!!!
