Jon Rahm has labelled the Official World Golf Rankings system as "a bit of a joke" after he clinched a third DP World Tour Championship since 2017 and landed his second victory in his last four starts around the world.
The Spaniard said the OWGR was "laughable".
DP World Tour chief Keith Pelley weighed in on Rahm and McIlroy's disagreement today.
Rahm, who clinched a record fifth Rolex Series title on the Earth Course in Dubai on Sunday, was then further pressed on what he made of the fact that he would not be moving up the world rankings despite winning the DP World Tour's season finale.
He has now finished 2-1-4-1 in his last four tournament starts around the world, yet has still not progressed from his fifth spot in the OWGR.
Rahm finished in a tie for second at the BMW PGA Championship in September, won the Open de Espana in mid October, finished tied fourth at the CJ Cup in late October and then just won the DP World Tour Championship today.
"I think this win keeps you at fifth in the world, but you are so much better than the No.5 in the world," Rahm told The Telegraph's James Corrigan.
Rahm paused, looked surprised, then said:
Jon Rahm loves the Earth Course. That’s a third DP World Tour Championship title since 2017. Incredible stuff from Rahmbo pic.twitter.com/7jo9U2TdcF— GolfMagic (@GolfMagic) November 20, 2022
Rahm has spent a cumulative total of 43 weeks as the World No.1 but he lost the title when Scottie Scheffler stole it from him back in March 2022.
McIlroy has since picked up the World No.1 post and has now held it for five consecutive weeks and a cumulative total of 110 weeks.
Despite playing in his final event of the season this week, McIlroy is guranteed to finish the year as World No.1 whatever happens.
