re: What was the reason for awarding UT runner second base in the 9th?

Coopers desire to throw the next pitch within 3 seconds of the previous one is why this got called. He rushes back on the dirt so eager the throw the next pitch that he's already there when the infield is throwing the ball to him when the previous play is over. Every other pitcher takes a few seconds, which is why a balk is almost never called when this trick is attempted.
