(updates at end of third round)
Aug 1 (Reuters) - Americans Troy Merritt and Kevin Chappell, both looking for their first PGA Tour wins, shared the lead after Saturday's third round lead of the Quicken Loans National, while tournament host Tiger Woods fell from contention.
Merritt set an early target with a course record 10-under-par 61 to go 14-under, a figure matched at the end of the round by Chappell, who shot a 67 for his 199 total at Robert Trent Jones Golf Club in Gainesville, Virginia.
One shot back on the crowded leaderboard was reigning Players Championship and Scottish Open winner Rickie Fowler after a 68.
