Olympic champion Xander Schauffele produced a grandstand finish to breathe some much-needed life into the Tour Championship in Atlanta.
World number one Scottie Scheffler, who started the week on 10 under par as the player with the most FedEx Cup points ahead of the season finale, was five shots clear after the opening round at East Lake.
And although the Masters champion remained out in front with a bogey-free 66 on Friday, he saw his lead slashed to two shots as playing partner Schauffele finished birdie, birdie, eagle in his 63.
