I just stuck in there really and had to make a couple of miracle shots to keep it ticking over, Broadhurst said.
Spanish Ryder Cup player Miguel Angel Jimenez was part of a large pack two shots back, while former U.S. Open champion Angel Cabrera of Argentina settled for a 71. Jimenez hasnt won in Spain in 10 years.
Jose Maria Olazabal returned from an injury to shoot a 70. The 42-year-old Spaniard, a two-time Masters champion, showed little signs of the back pain and fatigue that had plagued him since his last competitive round in June.
Federico Cabrera looked unlikely to follow his father, Angel Cabrera, into the weekend after shooting an 81 to sit second to last.
