Graeme McDowell equalled Rory Sabbatini's two-day-old course record with a six-under-par 64 in the final round of the Honda Classic in Florida.
That moved McDowell up from 30th to joint sixth on two under.
After turning in 33 the Northern Irishman holed from almost 45 feet at the 11th, added another birdie on the 13th and then finished with two more.
McDowell, who sank a 35-footer at the short 17th and then was on in two at the last, said: "It was a very different golf course today.
"The wind had switched and the 'Bear Trap' was a lot more civilised."
South African Sabbatini won the event by one stroke from Korean YE Yang.
