Bryson DeChambeau took renewed aim at golf's world rankings on Wednesday, describing them as "almost obsolete", after the LIV rebel slumped to a new low of 178.

The breakaway LIV circuit is yet to receive the green light for its tournaments to earn world-ranking points, adding to a slew of issues tearing golf apart.

Bankrolled by Saudi Arabia's Public Investment Fund, LIV split the sport last year by luring away top stars from the US PGA Tour and DP World Tour (formerly the European Tour) with lucrative contracts.

LIV has triggered accusations of "sportswashing" -- using sport to deflect from Saudi Arabia's human rights record, especially the brutal killing of journalist Jamal Khashoggi in 2018.
