Lee Westwood one shot behind four-way lead in Thailand

Lee Westwood sits one shot off the pace following a first-round 70 at the Thailand Golf Championship.

Thanyakon Khrongpha, Marcus Fraser, Richard Lee and Lee Wei-Chih all share the lead after carding three-under 69.

Westwood dropped three shots during his opening round, but five birdies kept him in contention for the title.

Martin Kaymer, who suffered a double bogey on the back nine, sits two shots behind, alongside Ryder Cup teammate Sergio Garcia after both carded one-under 71.

Darren Clarke and Victor Dubuisson were less positive in their rounds as both finished three-over-par.
