Lee Westwood saw a double bogey at the final hole ruin his chance of leading the Masters going into the weekend.

The Englishman was one shot ahead but three-putted for a six on the 18th to fall one behind AmericansJason Dufner and Fred Couples.

Veteran Couples shot a 67 to join Dufner on five under par for the championship.

Scotland’s Paul Lawrie remains inside the top ten after he birdied the last three holes for a 72, keeping him on three under.

Rory McIlroy, Sergio Garcia, Louis Oosthuizen and Bubba Watson are all well placed for a charge over the weekend.

Things are not looking so rosy for fellow Brit Graeme McDowell who made the cut on three over as did Luke Donald, Ross Fisher and Martin Laird on four over.

Tiger Woods’ bid to claim a 15th major title took a blow and he will have to make up eight shots after posting a score of 75 in his second round.
