Bubba Watson holed out with a 7-iron for eagle and tied the course record with a 9-under 63 Saturday to build a two-shot lead after three rounds at the Hero World Challenge.
Watson tied the record at Albany Golf Club set 10 minutes earlier by Paul Casey, who made nine birdies in his first 13 holes before closing with five pars for his 63 that left him two shots behind.
The tee times were moved up to avoid afternoon storms, and the conditions could not have been more ideal. Defending champion Jordan Spieth had a 68, leaving him four shots behind.
Six players are separated by four shots.
Tournament host Tiger Woods spent most of the day following along in a cart.
