U.S. Open champion Dustin Johnson moved to within three strokes of the lead held by Kevin Chappell, despite a double bogey on the 18th hole in the second round of the Deutsche Bank Championship on Saturday.
Johnson, the World No. 2, shot a five-under 66 at TPC Boston in Norton, Mass., to get to eight-under 134. He is tied for fifth with Smylie Kaufman.
Johnson came to the 18th hole a stroke back of the lead, but then his approach shot went wide to the right of the green and into the woods. He took a penalty stroke and three putts for a double bogey seven.
Chappell, seeking his first PGA Tour win, played the front nine in six-under 30 and finished his round at seven-under 64. He is in sole possession of the lead at 11 under.
Jimmy Walker, PGA Championship winner, shot a seven-under 64 to move into a tie for second with Paul Casey at 10 under.
Brian Harman is two strokes out at nine under following a six-under 65.
Olympic gold medalist Justin Rose is tied with Patrick Reed, Daniel Berger, Ryan Moore, Brian Stuard and Gary Woodland for seventh place at seven under. Reed is the current FedEx Cup points leader following his win at the Barclays last week.
Jordan Spieth and Sergio Garcia are five strokes back at six under, tied for 13th.
Rory McIlroy enjoyed a comeback round, shooting a four-under 67 to move to four under. He is tied with Henrik Stenson, Jim Furyk, Adam Scott and Emiliano Grillo.
Rickie Fowler is tied for 54th at two under along with Russell Knox and Louis Oosthuizen.
Jason Day's round was ruined by a quadruple bogey at the fifth hole and he ultimately finished the day at even-par 71. He made the one-under cut on the number.
Notable players to miss the cut included Brooks Koepka, Bubba Watson and Phil Mickelson.
