Bob Estes continues to lead the field at the Ginn sur Mer Classic in Florida, but his fellow halfway leader, Tommy Armour III has dropped off the pace along with Australian Michael Sim. After impressive performances over the first two rounds of the PGA Tour&aposs final tournament for 2007, Estes and Armour III led the field on 14-under. However, on the third consecutive day where play had to be suspended – this time for poor light – Armour dropped two strokes in his first 11 holes, allowing Estes and Sweden&aposs Daniel Chopra to lead the field. In his 12 holes on Saturday, Estes had a mixed round, posting five birdies and three bogeys to be two-under for the third round and 16-under overall. However, Estes, known as one of the great characters on the Tour, is coming under a severe challenge from Chopra who has raced into contention through a six-under 67 in the second round that was followed up in an interrupted third round with another three birdies and a bogey. Chopra is now level with Estes on 16-under, two strokes ahead of Briny Baird and Shigeki Maruyama, while Armour III is a further two strokes back on 12-under after posting two double bogeys and two birdies from 12 holes. For the Australasian contingent, Michael Sim was in the top 10 going into the third round, but only managed six holes before the poor light suspended play. However, in those six holes, Sim recorded one bogey, a birdie and a double bogey to slip back to eight-under overall, eight strokes astray of the leaders. Instead, Paul Gow has over-taken Sim as the best of the Aussies. Gow, needing at least a top 10 finish to potentially make it into the top 150 on the PGA money list – the top 125 – 150 allows players a provisional place on the tour next year – is on nine-under overall after carding a three-under round of 70 on the third day. However Gow, ranked 185th on the list, and Sim (177) are just two and three strokes respectively away from the top 10 and could potentially find themselves provisionally on the Tour in 2008. After Gow and Sim, Andrew Buckle was the only other Australian to survive the cut. He is currently at two-under for the round after 14 holes and four-under overall, although, having started on the back nine he has holes five to nine to complete. New Zealander Grant Waite also narrowly made the cut and is two-under overall after being on even-par after 15 holes on day three.
