Rory McIlroy's second round begins over an hour later than scheduled at BMW PGA Championship after play suspended following lightning

England’s Matthew Baldwin, who held a one-shot lead overnight following an opening 65, had increased his advantage to four strokes when the players were called off the course.

Baldwin had covered the front nine in 30 and was 12 under par after 16 holes of round two, with Andy Sullivan, Thriston Lawrence and former winner Billy Horschel all on eight under.

Play resumed at 1315 after a delay of an hour and 17 minutes, which was reflected in the tee times for the later starters.

Rory McIlroy, who had been due to get his second round under way at 1225, was now due to resume his bid for a second victory in the event at 1340.

The 2014 winner carded an opening 67 on Thursday despite seeing the head of his nine iron fly off down the 12th fairway as he hit his approach to the par five.
