Thanks to the United States Tennis Association's Equipment Out of Adjustment regulation, the sweat-related court conditions were treacherous enough that Millman was cleared to leave to change out of his sweat-soaked getup without consequences.
Eight of those statements have been about the heat, three have been about unruly chair umpires acting out of turn, and one was about an Australian player's excessive perspiration.
The US Open has been played out in sweltering temperatures - over the 30-degree mark most days - and crushing humidity.
Millman went up 1-0 and eventually held a 4-3 edge in the second set, until Djokovic came roaring back.
"You don't stop sweating, though. The sweating doesn't stop", Millman explained, according to ESPN.
If Djokovic wins in NY, he'll join Pete Sampras on 14 grand slam triumphs, a total only bettered by Roger Federer and Rafael Nadal.More news: North Korea holds military parade without showing ICBMs

This year's edition has been fairly smooth sailing for Djokovic, who has only dropped two sets en route to the semis and has switched up a gear in his last three matches. As play resumed, so did Djokovic's dominance and Millman literally had the air sucked out of him, this time for reasons not the weather. "It feels like sauna".
The common thread among almost all the U.S. Open matches this year is the excessive heat and humidity at Arthur Ashe Stadium in NY. We understand the conditions are very tough inside of Arthur Ashe Stadium.
'Whenever you have a loss, you tend to cop it'. The stadium has an air conditioning system of sorts - a water-cooled ventilation system blows air into the seating areas - but it's hard to effectively cool the cavernous, 24,000-seat facility.
Millman's upset win against Roger Federer, regarded by many as the best player of all time, in the fourth round of a grand slam was a career highlight for the proud Queenslander. Incredible. I mean, I have to take at least 10 shirts for every match.
