Cold weather, brisk breezes and overcast skies combined to make scoring less than suitable, but in the gloomy conditions, one man stood out like a blazing star on the grand seaside stage.
Leishman's round also was three strokes lower than anyone else who started the final round in the top 10.
The tall Australian burst from the first tee and turned a four-shot deficit after 54 holes into a three-shot lead by No. 11 tee.
Leishman's Odyssey Versa #6 with a black/white/black stripe pattern on the head was without question the difference-making club Sunday, starting right off with a 41-footer for birdie at the first.
The 36-year-old world number 28 was four back overnight but carded eight birdies to finish on 15 under.
"Pretty incredible, particularly with all the problems that have been happening back in Australia with the fires and people losing their lives". Earlier in the week, Woods said he was not thinking about No. 83. "The reality is setting in because I was just told about five minutes ago".
Tiger Woods still had fleeting hope of picking up his record 83rd victory, mainly because of a par.
Tiger Woods, who has won eight times at Torrey Pines including the 2008 US and will break a tie at 82 with Sam Snead for the most victories in PGA Tour history, posted a 70 and was six strokes back in a tie for ninth with Max Homa of Valencia and Cal (67), Patrick Rodgers of Stanford (68), Beau Hossler of Rancho Santa Margarita (68), Charlie Hoffman of Poway (65) and Harry Higgs (72).
Here's how the rest of the golf world reacted.
Woods shot a three-under 69 and finished the week at nine-under, in a tie for ninth. You dream to be on the PGA TOUR one day and all of a sudden to have five victories, it's a great feeling. "I waited until we got into the tunnel on 18 to tell him because I didn't want the cameras on him and see the shock on his face". It seemed like it came to him to the court, during match season, however he spent hours studying movie and attempting to work out the ideal way to become much better, and that is where he and I actually connected. I think I've led here early in the last round maybe once or twice and let it slip.
DUBAI, United Arab Emirates (AP) - Lucas Herbert marked Australia Day in his native country by capturing his first professional title, beating Christiaan Bezuidenhout of South Africa on the second hole of a playoff in the Dubai Desert Classic.
Woods blasted from a fairway bunker to 13 feet and sank the putt to open with a birdie, conquering the same first hole where he four-putted to a double bogey on Friday.
Most other players were not aware of the tragedy about two hours to the north during the round, including Rory McIlroy, a sports junkie who said he grew up idolizing Bryant.
The golf great explained that the pair would occasionally hang out when Kobe was still playing in the National Basketball Association and Woods had a home in California.
Clearly frustrated, Woods made no mistake in sinking his birdie putt.
Rahm finished with a two-under 70 on Sunday and a 14-under-par total.
Woods made bogey at the par-3 11th, coming up six-feet short on a 62-foot birdie bid and missing his par putt.
But in the end, it was Leishman's day, thanks in large part to his putter.
"I hit a great drive and a great second shot".
When he hit two strong shots to get to the back portion of the green, he thought his eagle putt was for the win. "I wish it could be like that every week".
