Gareth Maybin carded a second round 73 to comfortably make the cut on level par at the South African Open.
The Ballyclare golfer is eight shots behind the leader, England’s Andy Sullivan after a round that included four birdies, three bogeys and a double-bogey at the par four 16th.
Sullivan added a 70 to his opening 66 at Glendower Golf Club to reach eight under par, one shot ahead of former Masters champion Charl Schwartzel and eight clear of four-time major winner Ernie Els.
Tournament host Els, who has won the event five times, was just one shot behind Sullivan after an opening 67 but slumped to a second round of 77.
Schwartzel, who has yet to win his national open, finished birdie, eagle, birdie to record a 69 while Sullivan - who won a trip into space for a hole-in-one during the KLM Open last year - carded four birdies and two bogeys in pursuit of his first European Tour title.
Peter Lawrie missed the cut by one shot after finishing on three over.
The Dubliner followed up his opening round 71 with a second round 76.
