Bernard Tomic returns to the scene of his "tanking" controversy on Monday (Tuesday AEST) - only this time he won't have his coach and father John in his courtside box at the US Open.
Following the lead of French Open and Wimbledon officials, the USTA has "opted not to credential" John Tomic and is also considering banning him as a spectator at the season's final grand slam event in New York.
"Our desire is to make it as difficult as possible for him to gain entry to the US Open," USTA spokesman Chris Widmaier said ahead of Tomic's first-round match against Spaniard Albert Ramos.
"Our gate personnel that scan tickets have been informed that he's an unwanted guest.
"It would be within our right to escort him off the grounds. However, we have not determined what our exact policy will be at this time."
John Tomic was banned from tournaments by the ATP Tour and International Tennis Federation earlier this year after being accused of assaulting Bernard's hitting partner Thomas Drouet in Madrid on May 4.
He has denied assaulting Drouet, but remains on the outer, leaving his son to rely on Tennis Australia for on-site support at Flushing Meadows.
Tomic is back at Flushing Meadows for the first time since tennis great John McEnroe accused the youngster of "going the tank" during his 6-3 6-4 6-0 second-round pummelling at the hands of retiring American Andy Roddick last year.
The 21-year-old has since slipped to No.52 in the world - despite vowing after winning the Sydney International in January to finish 2013 inside the top 10 - and the head of Australian men's tennis Todd Woodbridge has challenged Tomic to "step it up".
"It's important that he has a good tournament," Woodbridge told AAP.
"It hasn't been the year he had hoped and he needs to finish the year strong and take momentum into 2014.
"This year has been like a rollercoaster ride for Bernie and it would be great to see him finish strong.
"Bernard has been forced to mature this year off the court and his attitude on court is also maturing. It's a natural process.
"What's interesting is how much longer it's taking all the game's young talent to achieve the high rankings and, from that perspective, Bernard is still on track to be winning slams in a couple of years."
Tomic has won just one match since reaching the last 16 at Wimbledon.
"Wimbledon was good for him and the US should be an excellent hunting ground for him," Woodbridge said.
"In the past, he won the juniors here and the speed of the court suits his game perfectly, so really he is due to step it up here."
Tomic admitted on Sunday he'd found it difficult to focus at times, but pledged to give his all on the big stage.
"It really brings out the best in you when you play in front of a lot of people," he said.
"I've been in difficult situations where I've played a few matches and where I haven't been as focused as I should have been and that comes from the experience.
"I'm still learning in that area."
Tomic has never played the 75th-ranked Ramos before.
"I've got a tough ask," he said.
"Every match here at the US open is tough. Nothing come's easy. You've got to work for it."
Three other Australians are also in first-round action against Spaniards on Monday, with teenage qualifier Nick Kyrgios facing fourth seed David Ferrer, Marinko Matosevic up against 19th seed Tommy Robredo and Ashleigh Barty meeting Estrella Cabeza Candela in the women's event.
