Marc Leishman realized he had at two-shot lead as he stood over a 6-foot birdie putt on the final hole at Torrey Pines.
Leishman finished at 15-under 273, one shot ahead of Rahm (70), who regrouped and birdied the final three holes, his long eagle putt at the last coming up just a few inches short.
"When I first came out on tour and started winning Majors, almost a decade ago, you could probably count the guys on one hand that played a similar game to the way I played", McIlroy said at Torrey Pines. "I didn't think he'd be to the point where he couldn't play golf, but I figured I'd wait to the end".
"This feels pretty awesome".
"Kobe Bryant was my HERO growing up", wrote Koepka.
"Eerily quiet on the grounds of Torrey Pines", he said.
The 24-year-old Herbert dedicated his victory to the people back home battling Australia's unprecedented wildfire crisis. With two Australian winners in the past three weeks on the PGA Tour, there was talk of karma pushing the Aussies forward. We all know that. "The reality is setting in because I was just told about five minutes ago".
Woods curled in a seven-foot birdie putt on the par-3 third and rolled in a 17-foot chip to rescue par at the fourth. He gained almost five strokes against the field on the greens with his putter in the final round, needing just 25 putts on the day.
I played a lot more conservative today... or had to on the back nine because I was in the rough on every hole. "If you can pack your patience around this place, just hang around, you should be OK. If you keep putting it on the green and give yourself chances, you're going to do well out here". McIlroy would have reclaimed the top spot on the Official World Golf Ranking with a victory. I made some good birdie putts early and then some great par saves later. His caddie told him, "Good try". You can be gone at any given time and we have to appreciate the moments that we have. "He's like, 'Nope, (Leishman) birdied 18.' And I didn't hear any roars or anything, so I just assumed he parred".
But talking with press reporters after the round, Rahm disclosed that he really did not take a look at one more scoreboard the remainder of the means.
McIlroy, needing a victory to return to No. 1 in the world, started three shots behind in the final group and opened with two straight bogeys.
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. "I wasn't expecting this at the start of the day", he added. McIlroy couldn't make up enough ground, shot 69 and tied for third with Brandt Snedeker (68). It wasn't in the cards for Woods who seemed to misread a surprising number of putts for a man who has won at Torrey Pines eight times.
Woods also commended Bryant's devotion to working on his match.
"Even if I hit the right speed, that putt doesn't go in", Rahm reasoned.
"It's a shocker to everyone, unbelievably sad, and one of the more tragic days".
