Thankfully he won but I thought the 3rd and 4th sets could have gone either way. He appeared to be having issues with the sun on his toss so that would account for some of the serving issues. And he just does not like the heat- it always makes him lethargic And I don't think acclimatizing to the heat/humidity conditions can occur with everyone. Genetics have to play a role in that as well.
And is it me or does the AO seem even slower this year?
I was having the hardest time watching.
