Right, it's a little closer when watching it in real time, but even so, what harm would it have done for the ump to have just punched him out and be done with it?
Would the Indians have argued the call? highly doubt it.

Highly unlikely the Indians were going to score 3 runs with 1 out to go anyway, just call the guy out.
Rob a guy of a hit.... or rob a guy of a perfect game.... hmm, tough call.
