Derek Lamely signed for a course record, 9-under-par 31-32=63 following his third round of the Puerto Rico Open.
The rookie hit 16 GIR and needed just 25 putts at Trump International, leading to 10 birdies. His lone miscue was a bogey at the par-3 11th hole. The 63 breaks Bo Van Pelt's 64 in 2008 as the low round at the tournament, now in its third year.
