Min Woo Lee is within sight of a maiden US PGA Tour victory after producing a third-round birdie blitz in Florida.
A 5-under-par 66 left the Australian fan favourite in a tie for fourth place at PGA National in Palm Beach Gardens.
He is three shots behind leading trio Shane Lowry (United States), David Skinns (Great Britain) and Austin Eckroat (United States) heading into the final round.
Lee drained eight birdies, including five on the back nine, to find himself in the top five entering the final round of a PGA Tour event for only the second time.
The West Australian is already a two-time PGA European Tour winner and is now one strong round away from joining his world number five sister Minjee Lee as a US tour victor.
He shares fourth at 10-under with American Jacob Bridgeman (65), Scot Martin Laird (66), Taiwan's Kevin Yu (70) and Frenchman Victor Perez (70).
Min Woo and Minjee Lee will appear on Australian Story on Monday at 8pm AEDT on ABC TV, ABC iview and YouTube.
