The start of the third round of the BMW PGA Championship was delayed by at least three hours on Saturday following heavy overnight rain.
Parts of the West Course at Wentworth were left under water by the downpours and that meant greenkeeping staff needed more time to prepare the course, with further rain also forecast.
Consequently the 74 players who made the cut were assembled in groups of three rather than two, with joint leaders Thomas Bjorn and Shane Lowry joined by Spain's Rafael Cabrera-Bello and due out at 2.15pm.
Bjorn and Lowry held a four-shot lead over Cabrera-Bello and two-time winner Luke Donald, with world number three Henrik Stenson, two-time major winner Rory McIlroy and in-form Swede Jonas Blixt another shot back on five under.
Donald's second round of 67 was the lowest round of the day on Friday, the former world number one carding six birdies and an eagle after the weather improved in late afternoon, a run of five threes in succession from the eighth culminating in an eagle on the 12th.
