At this point in his career, Jon Rahm has no use for finishing second. The world No.1 shot a final-round 67 at the Mexico Open in his title defence to end the week at 21-under total, three shots behind winner Tony Finau.

With the performance, however, Rahm jumped to the top of one more list. He’s already at the top of the Official World Golf Ranking. He leads the PGA Tour’s FedEx Cup standings. He has the most wins for the season, with four, including the Masters last month.

By earning $US839,300 at the Mexico Open, Rahm has now earned $US14,462,840 for the season, which breaks the PGA Tour record. Just as April becomes May.

Scottie Scheffler set the tour record last year with $US14,046,910 in earnings during his four-win season that ended with his first Major championship and PGA Tour Player of the Year honours.

Coincidentally, Scheffler is third on the career list for season earnings with the $US12,508,495 he’s already earned this season by winning twice, including the $US4.5 million that he took home at the Players Championship in March. He’s just less than $2 million behind Rahm this year, but with three Major championships, the playoffs and three other designated events left in the four months that remain in this season, the money race is far from over.
