Ok ... a few things of observation, and for discussion.
1) great call here no doubt
2) even though a great call ...... did Hal Gibson actually see the runners leg above the plate? Or, was his ruling out on the fact that he was tagged before his lead leg reached home. I'm not sure he can see a lifted leg, ...NOT THAT HE CAN'T ...I'm just saying...it's got to be really difficult to see that detail in real time.
3) Gibson has a Platinum TW retrofit w/ the throat cushion taken off
