Robert Rock leads Joburg Open January 13 2012

Englands Robert Rock took the lead in the Joburg Open in the second round before a thunderstorm halted play for the day. Robert has a score of 11 under par after posting an eagle and four birdies.                                             Jamie Elson, one of the leaders after the first round, was unable to start, it has yet been reported why. Damien McGrane, who shared that first-round lead with Jamie Elson, was one over after three holes on Friday. The second round will have to be completed tomorrow, an anxious wait for Charl Schwartzel to see if he makes the half way cut.
