Gah, is it that he can't throw a strike there or that he is trying to be too fine? Really, if it's the second one, just groove it with heat. The batter will more than likely make an out.
Safe at first, umpire wasn't in position to make that call as he was still deciphering whether it was fair or foul. His body language made it seem like he knew he made a mistake as well.
After playing years of baseball growing up I joined a beer league softball and started in LF. First inning there is a line shot to me and I try to go home with it to get the runner and airmailed the ball over the fence. The throw on that fateful day was better than Stanton's last throw.
