March 7 (Reuters) - Tyrrell Hatton survived brutal conditions to eke out a two-stroke lead over Rory McIlroy and Marc Leishman in the third round at the Arnold Palmer Invitational in Florida on Saturday.
Hatton sank an unlikely 30-foot birdie at the final hole to shoot one-over-par 73 and open a handy buffer over his rivals at Bay Hill in Orlando.
The Englishman is at six-under 210, while Northern Irishman McIlroy (73), who bogeyed the last after firing his second shot into rocks, and Australian Leishman (72) are tied for second on four-under.
South African Christiaan Bezuidenhout, South Korean Im Sung-jae, New Zealander Danny Lee and American Harris English are three strokes behind.
Sung Kang, who shared the halfway lead with Hatton, triple-bogeyed the final hole after pulling his drive out-of-bounds. He shot 78 and fell five behind.
Kang was not the only player to run up a big number on a day of carnage as strong winds, rock-hard greens and thick rough conspired to prevent anyone from breaking 70 at the event for the first time in 40 years. (Reporting by Andrew Both in Cary, North Carolina Editing by Nick Zieminski)
