Tiger Woods won his third PGA Tour title of the season at the AT&T National, fending off challenges from compatriots Anthony Kim and Hunter Mahan.
Woods, who was hosting the event, was out in the last group with Kim, but a course record-equalling 62 at Congressional Country Club from Ryder Cup star Mahan set the clubhouse lead at 12-under par.
The 14-time Major winner slammed in a critical 20-foot birdie putt on 16 as Mahan warmed up for a potential play-off, but the world number one carded pars on the testing final two holes to deny his fellow American.
Woods also made history by winning his own event, joining legends Arnold Palmer and Jack Nicklaus in that elite group – the latter pair having hosted and won the Arnold Palmer Invitational and Memorial Tournament respectively.
Kim, who was paired with Woods in a PGA Tour event for the first time, played himself out of contention largely due to a bad day on the greens.
