The Englishman Tyrrell Hatton takes a lead of two shots in the final round of the Arnold Palmer Invitational.
The world number 32 has the last one one-over 73 and a total of six below when looking for his first PGA title.
Rory McIlroy from Northern Ireland, winner in 2018, has also carded a 73 and shares second place with winner 2017, Marc Leishman.
Whirling winds and fast, fried greens made scoring dangerous on Bay Hill, with American Max Homa the only player under par for the day.
The cruel circumstances saw world number three Brooks Koepka card being the card highest lap of his PGA Tour career with a nine-over 81 that left him in a 64th place share.
Homa returned a 70 despite a double bogey at the end, leaving him 16th.
Joint leaders of the night, Hatton and Sung Kang, stood near the corner just before seven o'clock before the Englishman found a bunker and then pushed three times to double the ninth.
Kang went even worse, however, when he made a triple bogey seven after having found water twice on the 11th time and in the end encountered a triple to drop one.
McIlroy took part of the lead after a 365-meter ride when the fifth par created 16th his only bird of the day and he safely two-wells from 95 feet to parse the next hole.
A shot only went after his second finish on the rocks to the right of the green, but Hatton – fourth behind Leishman in 2017 – overcame an increasingly cool afternoon with two birdies in the last three holes.
He rattled in a putt of more than 20 feet for only the third birdie of the day at the 453 yard par four 18th hole.
