I was at the game on 9/10/2001, and it was against the Red Sox. Clemens was going for his 20th victory that season, but the game was rained out, it was raining horribly!!
I would have to look at the schedule, but I didn't think the White Sox were on the heels of the Red Sox and I thought there was a game breather in between, could be wrong though, as my memory from those next few days were crazy as I was staying in lower Manhattan and viewed the whole thing
