I don't know what the rule is there, but just because you don't agree doesn't make him wrong. He damn well may be right even if the umps totally freaked us on that one.
Good job Burnett
If he sees something that he thought was an improper call he can overrule. It's not like it's NEVER happened before.
It was the wrong, wrong, wrong call.
Looking at the replay, it looked like he tagged his foot. I did not see empty space in between the glove and his leg/foot. Looked like he touched him.
The ump was wholly in the wrong. You can't overturn that call.
