Dyson cleaning up in Tshwane

England's Simon Dyson maintained his bid for a seventh European Tour title with a second round of 68 in the Tshwane Open on Friday.

Dyson held the clubhouse lead overnight thanks to completing a seven-under-par 65 shortly before an approaching thunderstorm forced the players off the course, with play later abandoned for the day.

South Africa's Trevor Fisher was also seven under with two holes to play and although he bogeyed the first of those when play resumed this morning, a birdie on the 18th saw him join Dyson at the top of the leaderboard.

Both players were then soon back in action for round two and Dyson carded six birdies and two bogeys to join Spain's Carlos del Moral in the clubhouse on 11 under par, one behind Denmark's Morten Orum Madsen who had two holes remaining.

Dyson is playing his sixth event since being handed a suspended two-month ban from the European Tour following his disqualification from the BMW Masters in October.

The 36-year-old was seen to deliberately press down a spike mark to improve his position during the second round, despite knowing it was against the rules.

However, he was cleared of "a premeditated act of cheating" by a disciplinary panel in December and given a two-month ban, suspended for 18 months, something which he says has rekindled his love of the game after fearing a stiffer punishment.

Del Moral, who won the qualifying school at the end of last year to regain his playing privileges, had carded a flawless 65 and had not dropped a shot in 36 holes, despite the 7,964-yard Ernie Els-designed Copperleaf course being the longest in European Tour history.

Madsen, who won the South African Open at the end of November, looked like dropping a shot on his final hole after his drive found a semi-plugged lie in a fairway bunker.

But the Dane produced a superb third shot to within three feet of the flag to save par and return a flawless 65, leaving him 12 under par and one clear of Dyson and Del Moral.

South African trio Fisher, Darren Fichardt and Jake Roos were on 10 under as they looked to claim a sixth win for home players from the eight European Tour events being staged in South Africa this season.

However, defending champion Dawie van der Walt - who beat Fichardt by two shots 12 months ago - had missed the halfway cut after rounds of 78 and 74.
