Newly crowned US PGA champion Jason Day is already relishing the prospect of another head-to-head shootout with world No.1 Jordan Spieth at this year’s Presidents Cup.

Day slammed the door shut on Spieth in a high-quality final-round duel at Whistling Straights to land his long-awaited maiden major championship on Sunday.

Day’s breakthrough victory lifted the Australian to No.3 in the rankings behind only Spieth and Rory McIlroy.

While Day and Spieth may well battle it out again beforehand during the US PGA Tour’s FedEx Cup playoffs, Australian golf’s new golden boy says it’d be something special to square off with the world No.1 in a genuine matchplay environment at the President’s Cup in Korea in October.

The Internationals will be trying to topple the star-studded USA line-up for only the second time in 10 encounters – and for the first time since 1998 – and Day and Spieth will almost certainly be the respective teams’ No.1s.

“I would absolutely love to play Jordan in the singles,” Day said in a teleconference on Wednesday.

“Not only would it be fun, it would be very competitive, a fantastic challenge for both of us.

“I think both of us really enjoy going head to head. There would be a lot of pressure.

“I feel like it would be very exciting because we’re both very fierce competitors and we both want to win so bad.

“But, by the end of the round, we’d be happy for each other because we more enjoy the competition and the challenge rather than really hating each other or anything like that.

“We’re actually good friends and we just enjoy playing against each other.”
