The seeds for the 2018 US Open are set. Three-time champion Rafael Nadal, the No. 1 player in the ATP Rankings, will lead the field when play gets underway on Monday. The Spaniard will go for his second Grand Slam title of the season and look to match his 2017 Grand Slam haul by winning Roland Garros and the US Open.

Second seed Roger Federer will also be vying for his second Grand Slam title of 2018. The Swiss currently has 20 Grand Slam crowns, only three ahead of Nadal’s 17. Juan Martin del Potro, who’s at a career-high No. 3 in the ATP Rankings, will try to replicate his 2009 US Open run and hoist his second Grand Slam trophy.

Novak Djokovic’s surge at the Western & Southern Open in Cincinnati last week landed him the sixth seed. Djokovic became the first player to win the Career Golden Masters by beating Roger Federer in the final of the ATP World Tour Masters 1000 event in Ohio.

Less than 48 hours after becoming the first man in history to complete the Career Golden Masters, Novak Djokovic was awake bright and early Tuesday for an appearance on NBC’s breakfast show, Today, in New York City.

“It feels great [to complete the Career Golden Masters]… It is amazing to be in New York and obviously for the first time, at my sixth attempt, to win Cincinnati,” said Djokovic. “It’s probably the biggest challenge you can have in tennis, to win all the Masters.”

The 31-year-old, fresh off his recent win over Roger Federer at the Western & Southern Open, is already in New York City as he begins preparations for the final Grand Slam of the season. The two-time champion joined Hoda Cobb, Savannah Guthrie, Craig Melvin and fans for a quick visit as excitement begins to build ahead of Monday’s start of the US Open. Djokovic, who most recently lifted the trophy in 2015 (also 2011), owns a 62-10 record at the USTA Billie Jean King National Tennis Center.

After missing the 2017 tournament due to injury, Djokovic will be making his first appearance at the event since his runner-up finish to Stan Wawrinka two years ago. The 70-time tour-level titlist will be seeded sixth, with defending champion Rafael Nadal and five-time winner Roger Federer occupying the No.1 and No. 2 spots, respectively.

“I’ve been through a difficult journey with an injury that kept me away from the Tour for the second part of last season,” said Djokovic. “For sixth months I was away, I [did not] play the US Open. It was the first Grand Slam I had missed… I’m really glad I am back on track. I recovered well and I am playing at my best at the moment. It is the best possible way to prepare for the US Open.”
