(Reuters) - American Daniel Berger moved within sight of his second victory in two months when he opened a three-shot lead after the third round of the Travelers Championship in Cromwell, Connecticut on Saturday.
Berger, last season's rookie of the year on the PGA Tour, picked up nine birdies to surge clear with an eight-under-par 62 at the TPC River Highlands.
The 23-year-old posted a 15-under 195 total, three ahead of Scotland's Russell Knox (64), South African Tyrone Van Aswegen (65) and American Russell Henley (65).
Low scores were plentiful on a day when Ernie Els made his first ace on the PGA Tour since 2004, using a seven-iron from 171 yards at the 16th.
