Overnight leader Chad Campbell carried on where he had left off on Thursday, making two early birdies to extend his lead in the second round of the Masters Tournament at Augusta National.
Two closing bogeys in his opening round had given Campbell ‘only’ a 65 after he had threatened to break the major championship record at nine under par with three to play.
He was one in front of Hunter Mahan and Jim Furyk when he resumed and, although Mahan instantly added a birdie to his tally, Campbell was unruffled and collected two early birdies to move back to nine under.
Mahan then ran up back to back sixes at the second and third holes to drop back to four under, while fellow American John Merrick reached the turn in 34 before bogeying the 10th to sit four shots behind Campbell.
Merrick was playing alongside Larry Mize, the 50-year-old who was champion in 1987 and who had opened with a 67.
Mize had a shock to his system when he double bogeyed the opening hole, then came back with back-to-back birdies only to drop another shot at the fourth.
Northern Ireland's Graeme McDowell, who like England's Ross Fisher got to five under on Thursday before bogeying the 17th and 18th, birdied the long second but bogeyed the seventh to return to three under, the same score as Argentina’s Andres Romero.
Ian Poulter remained on his overnight score of one under after completing his front nine in 36 shots.
