Sihwan Kim swept his second tournament in two months on Saturday, winning the Asian Mixed Stableford Challenge in Thailand as local teen sensation Ratchanon Chantananuwat suffered disappointment after his record-breaking victory last week. Sixty players from the men's Asian Tour and Ladies European Tour teed off in the $750,000-prize tournament which wrapped up Saturday at Siam Country Club's Waterside Course near Pattaya. Kim scored seven points in the final round for a 49 point total, under the modified stableford scoring system.
