WENTWORTH (England), May 25: Denmark’s Anders Hansen fired a seven-under-par 65 for a two-shot lead in the Volvo PGA Championship’s second round on Friday as overnight leader Colin Montgomerie slipped back after injuring a spectator with an errant drive.

The 31-year-old Hansen finished the day at 11-under-par 133 at Wentworth’s West Course while Montgomerie hit a 71 and was nine under overall.

The seven times European number one dropped three shots in his last four holes to share second place with Argentina’s Eduardo Romero, who carded a 68 on a day of gusting winds and occasional showers.

The 38-year-old Scot was tied for the lead with Hansen standing on the 16th tee but then struck a spectator on the back of the head when he pulled his drive well left.

The spectator, Englishman John Edom, was felled and, after recovering consciousness, received treatment from on-course medical staff.

He had his head bandaged and then shook Montgomerie’s hand before being taken to hospital as a precaution, tournament officials said.

“Colin was visibly distressed by the incident and enquired about Mr Edom’s health after finishing his round,” Montgomerie’s manager Guy Kinnings said in a statement.

Hansen dropped a shot at the par-four first but then collected eight birdies to hold the early clubhouse lead.

Romero, who fired an opening 67, eagled the par-four 11th when he holed his second shot with a nine iron from 135 yards from under some trees and, for a while, was the outright leader at nine under.

But the moustachioed Argentine dropped a shot at the long 17th before collecting his third birdie of the day at the last and had to settle for a 36-hole total of nine-under-par 135.
