Anirban Lahiri hit a terrible stretch on the front nine, where he dropped four shots in four holes, to finish the week with a card of 73 and in a disappointing tied-51st place at the Shriners Hospital Open on the PGA Tour.
Lahiri, who earlier carded rounds of 69, 72 and 71, finished at one-over 285.
The Indian, who began the 2017-18 season with a T-10 in CIMB Classic and T-5 at CJ Cup in Korea, bogeyed fifth, double bogeyed sixth and again bogeyed eighth to be four-over at that stage. Birdies on ninth, 17th and 18th repaired some damage, but in between there was a bogey on 12th.
Meanwhile, Patrick Cantlay, who appeared to be cruising to victory in regulation, bogeyed the final two holes in a nervy finish to drop into a share of the lead with Alex Cejka and Whee Kim on nine under par.
In the play-off held in fading light, all three players failed to hit the green with their approaches to the 18th.
They were also unable to get up-and-down as Cejka came closest to winning outright when his 15-foot putt for par shaved the right edge.
After returning to the 18th tee, Kim went out as he pulled his drive into the desert and took an unplayable lie.
Cantlay blocked his tee-shot into the right rough behind a collection of trees.
Cejka could not take advantage as he came up short and right with his second before Cantlay took the bold decision to go for the green rather than pitch back out to the fairway.
That worked and the ball landed on the green. Cantlay two-putted in near darkness, while Cejka left himself a 15-footer and missed it for par.
Kim missed a bogey and Cantlay won with par.
So, the former amateur world No 1 Cantlay won for a two- year exemption on Tour.
