In doling out the fine, the ATP again said it was considering a "major offense" punishment against him, considering that he got kicked out of the Italian Open in May for throwing a chair and had previously been suspended in 2016 for tanking and for insulting fans at a tournament in China.
Nick Kyrgios is no stranger to on-court antics, including an outburst at the Western & Southern Open on August 14 that generated $113,000 in fines.
He later backed away from the comments but remains under a suspension cloud after being heavily fined following his antics towards match officials in Cincinnati earlier in the month.
"I was fined $113,000 K for what?"
"Why are we talking about something that happened three weeks ago when I just chopped up someone [in the] first round of the US Open?".
The reporter replied by saying that his penalty was a substantial fine and now was the time to ask his reaction.
"The comments made by Kyrgios after his 1st rd match in NY will be assessed under Player Major Offense provision under ATP Rules", the ATP said.
Here at 10 daily, we've written too many times to count about how there is good Nick Kyrios and bad Nick Kyrgios, and how you can nearly bet that you'll see the opposite version from tournament to tournament.
When asked whether the fine bothered him Kyrgios originally responded: "Not at all". Just answer my question.
This won't be the last we hear of Kyrgios at the U.S. Open, from any angle.
The ATP offered no timeline around when it would make any decision on Kyrgios's fate when quizzed on the eve of the Open, which started on Monday. In the same section of the code of conduct that covers the "major offence" rule, the one that could throw the Australian out of the game for three years, there is a section that covers "the integrity of the game".
The Australian world No 30 lashed out at the ATP following his US Open first-round win over Steve Johnson in the early hours of Wednesday morning.
Not content to let matters lie, Kyrgios demanded to know why Keothavong wasn't doing more to control the crowd.
"I actually came to NY".
"He always tells us he doesn't train a lot, but I don't necessarily buy into that".
Kyrgios was actually on good behaviour for most of his match, and it should be said that there is some truth in his assertion that the rules are not always universally applied.
"I felt like I was moving well, playing well".
Nick Kyrgios delivered heaps of brilliant shotmaking and a sprinkle of controversy in a 6-3 7-6 (1) 6-4 win over American Steve Johnson on Tuesday that put the Australian into the second round of the US Open.
All-American Alabama LB Dylan Moses has torn ACL
This could lead to some roles and assignments shifting too as the Crimson Tide have a lot more experience at outside linebacker. Alabama Head Coach Nick Saban stated Moses will require surgery and will be out for "an indefinite amount of time".
