GAINESVILLE, Va. — Troy Merritt shot a tournament-record 10-under 61 on Saturday for a share of the lead with Kevin Chappell after three rounds in the Quicken Loans National.

Merritt moved to the top of the leaderboard even before the second-round leaders hit their first shots. He had 11 birdies and a bogey on the par-5 eighth hole.

Chappell had a 67 to join him at 14-under 199.

The challengers at the tournament midpoint included Tiger Woods, but the two-time champion and tournament host was errant off the tee early, gave back three strokes in his first 12 holes and finished with a 74 to drop into a tie for 42nd at 5 under.

Rickie Fowler was one shot back after a 68, and Jason Bohn (67), Whee Kim (67), Charles Howell III (67) and David Lingmerth (68) were 12 under with a round left at Robert Trent Jones Golf Club.

LPGA: Jin-Young Ko of South Korea and Teresa Lu of Taiwan shot 3-under 69s to share the lead after the third round of the Women’s British Open at Turnberry, Scotland, with both players chasing a first major title.

Second-round leader Suzann Pettersen is a stroke behind their 8-under total of 208 after shooting 72 on a day of changeable weather on the Ailsa links.

Chasing victory to complete a career Grand Slam, top-ranked Inbee Park (69) is in a three-way tie for fifth place, with world No. 2 Lydia Ko (72) and Minjee Lee (70).

The 20-year-old Jin-Young Ko is the surprise of the tournament. She is playing in her first major, has never played links golf, and has hired a temporary caddie for the event. They met for the first time on Tuesday.

CHAMPIONS TOUR: Defending champion Kenny Perry had a hole-in-one and matched the 3M Championship record with an 11-under 61 to take a four-stroke lead at Blaine, Minnesota.

Perry played the first eight holes in 7 under, making the ace on the fourth hole, and had two birdies on the back nine and closed with an 18-foot eagle putt on the par-5 18th. He had a 14-under 130 total at TPC Twin Cities.

Kevin Sutherland and Scott Dunlap were tied for second. Sutherland had a 65, and Dunlap shot 67.

Minnesota native Tom Lehman, the first-round leader after a 64, had a 71 to drop into a tie for fourth at 9 under with Bernhard Langer and Marco Dawson. Langer and Dawson each shot 67. Langer won the event in 2009 and 2012 and has two second-place finishes in his previous six appearances. Dawson won the Senior British Open last week in England.

EUROPEAN TOUR: Pontus Widegren of Sweden will take a one-shot lead into the final round of the Madeira Islands Open, and hope of a first win on the tour.

Widegren offset two bogeys with two eagles before the turn, and finished the third round with a 5-under-par 67 to sit on a total of 16-under 200.

Widegren said he struggled on the greens, and was able to overcome a tough start by hitting “a nice eagle at No. 3” and building momentum.

Tied for second were Scott Henry of Scotland and Roope Kakko of Finland.
