Tiger Woods, in agony and in danger it seemed of having to pull out of the US Open last Friday, completed a simply staggering victory on Monday.
On the very day he reached 500 weeks as world number one, Woods took his total of majors to 14 - just four short of Jack Nicklaus's record - after a marathon duel with fellow American Rocco Mediate at Torrey Pines.
After staying alive with a 15-foot putt on Sunday Woods again birdied the last to stop 45-year-old qualifier Mediate becoming the championship's oldest winner.
They were both round in level par 71s as a result, Mediate having come from three down after 10 to lead by one on the final tee.
Woods then won his own version of the "Battle of Wounded Knee" when his opponent, ranked 158th in the world, bogeyed the first extra hole of sudden death. Their 91st of the week.
In his first event since surgery on his left knee straight after the Masters in April, Woods made it a remarkable five straight victories at the San Diego venue and took his on-course career earnings through the 100 million US dollars mark.
If not the greatest victory of all the 87 he has now had as a professional, it was certainly the most unlikely when he started with a double bogey and appeared miles short of full fitness.
His play-off record now, though, is a stunning 16-3 - and, of course, he has maintained his record of winning every single major he has led after 54 holes. All 14 of them, that is.
After Woods, battling as he had all week with the pain in his left knee, had bogeyed the 11th and 12th Mediate birdied the next three and went one ahead.
The last of those was with a 25-foot downhill putt after the 13-major winner had conjured up a magical recovery from a bunker on the wrong hole.
Woods, having missed from 12 feet there, almost made a 50-footer on the next and could not convert a 22-foot chance at the 17th.
Mediate, though, opened the door by driving into a bunker on the last. He had to lay up short of the water, whereas twice champion Woods hit a three-iron onto the green and two-putted.
Sudden death began on the seventh hole and there it ended as well when Mediate was in a bunker, missed the green and failed to get up and down.
Collated final round scores in the US Open, Torrey Pines GC, San Diego, California, United States of America (USA unless stated, par 71):
