NC State vs TCU NCAA Tournament game (Video)
 

In the 8th inning, the pitcher for NC State was called for a balk that tied the game after a big comeback.

Can anyone tell me what might have been the infraction that resulted in the balk call? ESPN showed highlights of this and I was trying to figure out what might have been the possible infraction?

Not saying the call was wrong, but all it appeared the pitcher did was step off the rubber. I did not see any other action, but I have not done baseball in awhile so I am wondering if there as something that was a POE or some action I have not seen in some time.

Just curious.

Peace

Can't tell from that angle. It's obvious that one of the base umpires (probably U3) made the call.

There may have been a knee buckle or something but I can't see anything from that angle.

I don't see a balk, have watched it many times from all angles available.
