Jose Maria Olazabal on the charge in South Africa as two birdies help him to share the lead at volvo Golf Champions But he was on 10 under par with South African trio Retief Goosen, Masters champion Charl Schwartzel and Branden Grace, with Belgian Nicolas Colsaerts - joint overnight leader with Grace - one behind after bogeying the first. Olazabal bogeyed the fourth, missing from five feet, and fell two behind when Goosen had another birdie on the third, but the double US Open champion followed that with a bogey. Olazabal was only one behind again after making a 12-footer on the short eighth and with Goosen mixing birdies with bogeys things could hardly be tighter. He and Schwartzel were 10 under, one ahead of three more major champions in Olazabal, Ernie Els and Louis Oosthuizen as well as Colsaerts. Harrington, though, fell six back with further bogeys on the seventh and eighth, but did at least birdie the long ninth to retain a slim chance. The five par fives were always likely to play a big part and, while Goosen ran up a seven on the ninth, Els sank an 18-foot eagle putt at the 13th and jumped into a one-shot lead. He was five under for the day and 11 under for the tournament, one in front of Colsaerts and two ahead of Schwartzel and Grace, while Olazabal's bogey at the 10th left him three back.
