Both players are inside the top 50 on the Official World Golf Rankings, with the promising 22-year-old Rahm currently ranked 38th thanks largely to his victory on the PGA Tour earlier this year.
Rahm and Na will now be able to earn Race to Dubai ranking points, beginning this week at the WGC-Mexico Championship, while Rahm will also be eligible to earn Ryder Cup points when the race to qualify for Thomas Bjørn’s European Team for Paris 2018 begins.
Providing they stay inside the world’s top 50, Rahm and Na would be eligible to play in any of the first five tournaments in the European Tour’s new Rolex Series – an alliance of eight events each with a minimum prize fund of US$7million.
Rahm has already represented Spain in the ISPS Handa World Cup of Golf, finishing eighth alongside 2016 Ryder Cup star Rafa Cabrera-Bello in Australia last November.
He was born in the Spanish town of Barrika before studying at Arizona State University, where he was the world’s top-ranked amateur before bursting onto the professional scene with six top-25 finishes in nine starts on the PGA Tour last season before his breakthrough win in January.
Rahm said: “It means a lot to me to join the European Tour – I’m European after all!
"I have always wanted to play the Ryder Cup and I have always wanted to be a member of the European Tour.
"I have obviously taken a different approach to tour life than a lot of other Europeans who went to college in the States, but I thought this was my best shot.
"I’m surprised I have been able to take this opportunity so early but it’s great to be able to join.
“I have so many memories of the European Tour – one that stands out was watching Justin Rose’s hole-in-one on the third hole at the Volvo Masters the year he won the Order of Merit at Valderrama.
"I remember Miguel (Angel Jimenez) winning the French Open; Pablo (Larrazabal) winning the French Open and then Pablo and Sergio (Garcia's) play-off at the BMW International too. I’m really looking forward to playing some tournaments on the European Tour.”
Na has previous experience of the European Tour, having played 14 events in the 2003 season – making 12 cuts – while he also played the UBS Hong Kong Open in 2006, the 2012 Aberdeen Asset Management Scottish Open and the Nedbank Golf Challenge at the beginning of the 2015 season.
