Parker McLachlin made a seven-over-par 12 on the par-5 seventh hole at Quail Hollow Thursday morning, tying the worst score of the 2010 PGA Tour season.
McLachlin, the 2008 Legends Reno-Tahoe Open champion, matched Michael Campbell's 12 on the sixth hole at Bay Hill earlier this year. John Daly's 18 in 1988, also on the sixth hole at Bay Hill, is the highest single-hole score on record with the PGA Tour.
The seventh hole at Quail Hollow measures 532 yards and is bordered by water right of the fairway. After shooting a 49 on the front nine Thursday, McLachlin bounced back with a birdie to start his back nine.
