Kuala Lumpur: Justin Thomas birdied his last two holes Saturday to share the 54-hole lead with Brendan Steele as several others lurked in contention in a superbly played CIMB Classic. Thomas and Steele were tied at 20-under-par thanks to respective third rounds of 67 and 66 at the par-72 Kuala Lumpur Golf and Country Club. Fellow American Kevin Na countered with an 8-under 64 to lie just a stroke back. There has been a bumper crop of ultra-low scores reaped on the warm and humid course, with nine rounds of 64 or less so far.
