JERSEY CITY, New Jersey (REUTERS) - Matt Kuchar completed a round of six-under-par 65 early on Saturday morning to claim a two-stroke lead after 36 holes of The Barclays, the opening event of the FedExCup play-offs.

Kuchar was at 11-under 131, with 2012 US Open champion Webb Simpson and long-hitting Gary Woodland tied for second at 133 at the halfway mark of the weather-hit tournament.

World No.6 Kuchar returned with 39 other players to complete the second round and put the event back on track after thunderstorms caused more than six hours of delays on Thursday's opening day.

The 35-year-old Kuchar birdied three of the five holes he had left to play, rolling in a 28-foot putt at the par-three 14th, and bogeyed the two others including the 18th.

Tiger Woods, playing in the same group as Kuchar, missed a 13-foot putt for birdie when play resumed at 14 after the suspension due to darkness on Friday, but birdied the 17th to improve to six under, five shots off the pace.

South African Charl Schwartzel, the 2011 Masters winner, finished up a second-round 67 to reach 135, a total he shared with reigning Masters champion Adam Scott of Australia, 2011 PGA champion Keegan Bradley, and Rickie Fowler.

Two-time Major winner Rory McIlroy returned on Saturday to complete a 65 that featured eight birdies to join a group of nine at 136.

Along with world No.1 Woods, the group also included US Open champion Justin Rose and fellow Briton David Lynn, Spain's Sergio Garcia, Sweden's Freddie Jacobson and Jonas Blixt, Brandon de Jonge of Zimbabwe and American Jim Furyk.
