Do a Google search for James Batie, Troy University hall of fame.
You will find anything you want to know. I did make one mistake, he was ranked 6th in the world not 4th.
BTW, I was present the day Batie ran a 9.3. I usually did not compete in the 100 but always ran a leg of the 440 relay.
I did run that day and ran a 9.7 which qualified me for nationals but both the coach and I knew I had no chance so did not go.
Did the search.
Could not find anything about him running 9.3 in the 100.
