An early eagle lifted Prom Meesawat into the lead as the final round of the Hong Kong Open began in Fanling.
The 29 year old from Thailand had already birdied the second when he found the green in two at the par five third and holed from 20 feet.
That took Meesawat, whose best European Tour finish came when he was third in Indonesia in 2008, to ten under par.
That was one ahead of overnight leader Stuart Manley, the Welshman bogeying the first after a wayward drive as he seeks a first European Tour title, Australian Qualifying School graduate Wade Ormsby and defending champion Miguel Angel Jiménez.
The Spaniard became The European Tour’s oldest winner with his third victory at Hong Kong Golf Club a year ago, and the 49 year old birdied the third from 12 feet as he looks to break his own record.
Manley drew level with a birdie at the long third, then had two birdies and two bogeys in the next four holes.
Meesawat, meanwhile, birdied the sixth and went to the turn in 30, but Manley joined him on 11 under when he holed a 12 footer for birdie at the short eighth.
Dutchman Robert-Jan Derksen chipped in at the 12th for one of four unanswered birdies over his first 14 holes to be one behind along with Jiménez.
Manley miscued his approach to the tenth and bogeyed to leave Meesawat in front on his own.
And the Thai responded by pulling three clear with his second eagle of the day from 50 feet at the 13th.
Meesawat dropped a shot at the 14th after failing to get up-and-down from just off the edge of the green, and with Jiménez splashing out a greenside bunker to ten feet and holing his lead was immediately back to one.
Jiménez drew level with a birdie from two feet at the 14th, and Meesawat did well to stay in a share of the lead by rescuing par from 30 feet at the 16th after finding a bunker with his approach.
A dramatic afternoon took another twist when Jiménez three-putted the 15th and dropped a shot.
That left Meesawat leading by one on 12 under, with Jiménez and Derksen one behind – the latter setting the clubhouse target after making a fine birdie at the last.
Meesawat parred his way in to set the benchmark at 12 under after a 65, with Jiménez and Manley one behind on the course.
The Spaniard then birdied the 17th from ten feet to leave matters tied at the top once more.
