Jon Rahm has successfully defended his LIV Golf season points title without winning an event all year, closing with an 11-under 60 before losing a playoff to Sebastian Munoz on the first extra hole in the Indianapolis event.

Munoz won two days after becoming the first player to shoot 59 with a double bogey. The Colombian — with Rahm hitting balls on the driving range — birdied the final two holes in regulation for a 65 to match Rahm at 22 under at The Club at Chatham Hills.

Rahm also lost on the first extra hole last week outside Chicago, falling to Dean Burmester in a three-way playoff that included Josele Ballester. On Sunday, Munoz beat the Spanish star with a birdie on the par-4 18th in the playoff.

Rahm took the season points title from Chilean Joaquin Niemann, a five-time winner this season. Niemann shot a 66 to tie for fourth at 17 under, his first top-10 finish of the year that he didn't win.

Munoz led Torque GC to the team event championship, finishing at 64 under to break the LIV record of 53 under.

Cameron Smith (67) was the best-placed Australian at 13 under and in a tie for 14th.

Compatriots Lucas Herbert (67) completed his three rounds four under the card, Matt Jones (67) three under and Marc Leishman (73) two over.

The all-Aussie Ripper GC came home in 13th, and last, at 18 under.

Ian Poulter birdied four of his last five holes for a 67 to tie for 17th and avoid relegation from the tour. Majesticks teammate Henrik Stenson was relegated, missing a 20-foot birdie putt on the final hole that would have keep him on the tour and left Poulter out.
