Unheralded journeyman Kim Chang-yoon fired a course-record 10-under-par 62 on Friday to lead after two rounds of OneAsia's SK Telecom Open on South Korea's Jeju Island. Kim's ten birdies left him at 14-under after day two of the tournament, one stroke ahead of overnight leader Matt Griffin (67) from Australia. Fellow Australian Jason Norris posted his second 66 for sole possession of third place at the Pinx Golf Club, with Korea's Park Do-kyu (66) one more behind.

Belgium's Nicolas Colsaerts boosted his chances of successfully defending his title with victory on day two of the Volvo World Match-Play Championship in Bulgaria on Friday. The 30-year-old easily accounted for Thailand's Kiradeck Aphibarnrat, winning 3 and 2 on the Thracian Cliffs course along the Black Sea shoreline. Colsaerts was a shock first round-robin loser to South African Branden Grace but was always in command in his match with Aphibarnrat, winner earlier this year of the Maybank Malaysian Open.

Ian Poulter's impressive match-play record will be tested in this week's historic Volvo Match-Play Championship at Thracian Cliffs in Bulgaria. Poulter, a former double winning event champion and hero of last year's European Ryder Cup team triumph, was uncharacteristically lost for words when asked if he could name any course similar to this week's host venue. The spectacular Gary Player designed course is laid out over four kilometres on a cliff top overlooking the Black Sea.
