Pacific Palisades, California …

Four-time Major winning Jordan Spieth sank to his highest score in over four years in posting a shock final round 81 in the rain-affected Genesis Open at Riviera.

Spieth who was near the lead thanks to a 64 at the end of the opening day and then was sharing eighth place with a round to play, slumped to an eventual tie for 51st place at one-over par.

The Texan’s last round began on a positive note with a first hole birdie but the current World No. 23 proceeded to play the second to 10 holes in 11-over par.

Spieth doubled the second, bogeyed the third, tripled the fifth, bogeyed the eighth and then posted a quadruple fat-lady bogey ‘8’ at the short downhill par-4 10th hole to slump to 10-over par for his round.

Then, and as if someone else had jumped into his shoes, Spieth pared his remaining eight holes including a surprising end to his round and with Spieth delighting a huge crowd gathered around the 18th when he chipped-in from the left fringe for a saving par.

It was Spieth’s highest round since a third round 80 at the 2014 season-ending Tour Championship, and his score was just one shot shy of matching his worst score on the PGA Tour and that was an 82 on day three of the 2013 Memorial.

Spieth was asked after his round for a comment but he politely declined saying:  “Thanks fellas.  We’ll do it next time.”

In posting a first round 64 Spieth recorded just 21 putts but posted 34 on day four.
