Tiger Woods shaved 11 strokes off his career-worst 85 of Saturday with a three-over par 74 to conclude his Memorial tournament.
The 14-time major champion was the first man off the tee, in last place in the weekend field of 71 at a tournament he has won five times.
The odd number of players meant he didn't even have a playing partner, but the former world number one said he approached the round as he had every other in his career.
"To try and shoot the best score I can," he said of his goal.
"Just because I'm in last place, that doesn't change anything."
Woods, who has slumped to 172nd in the world, finished with a 72-hole total of 14-over 302.
That was another career worst, surpassing the 72-hole high of 298 at the 2010 Bridgestone.
Erratic off the tee all week, Woods was making progress on the front nine, following an early bogey with three birdies.
A birdie at the par-five 11th, where he sank a four-foot putt, put him three-under for the day.
But Woods, who insists he's committed to working through the swing changes he's implementing with instructor Chris Como, couldn't maintain the momentum.
A bogey at 13 was followed by a double-bogey seven at the par-five 15th.
A birdie at the par-three 16th was followed by a bogey at 17 and a double bogey six at 18 - where he had finished with a quadruple bogey eight on Saturday.
"This is a lonely sport," admitted Woods, who has less than two weeks to regroup before the US Open at Chambers Bay.
Meanwhile, the BBC remains "committed" to televising the Open Championship for the next two years, despite a report claiming its current deal could end a year early.
It was confirmed by the R&A in February that Sky Sports has been awarded exclusive rights to live television coverage in a five-year deal from 2017, with the BBC offering two-hour daily highlights and live coverage on radio and online.
A newspaper report said the BBC was considering ending its live television coverage after this year's event at St Andrews, a move which would reportedly save the corporation around £7million.
However, a BBC spokesperson said: "We remain committed to our current contract with the R&A."
Sky Sports did not immediately respond to a request for comment.
High-profile players voiced their disappointment about the move to Sky, with former world number one Lee Westwood branding it an "absolute disgrace''.
In an open letter published when the deal was confirmed, outgoing R&A chief executive Peter Dawson insisted "numerous factors'' were taken into account and played down talk about the relationship between free-to-air viewing and participation.
Dawson said: "I recognise that this new broadcast model represents a significant change and I understand that change is controversial.
"Numerous factors were weighed in this process such as quality of coverage, household reach, innovations in the broadcast, commercial considerations and promotion of the Open and our sport throughout the year."
