BARCELONA: Scotland's unheralded Scott Jamieson topped the Spanish Open first round leaderboard Thursday and hoped his experience of playing at Augusta's fabled Masters course would help him to a debut title. Playing in just his 11th European Tour event, the 27-year-old shot a six-under-par 66 to be one ahead of England's Steve Webster, Jeev Milkha Singh of India, France's Romain Wattel and Spaniard Pablo Larrazabal. Jose Maria Olazabal had to settle for a level-par 72, while Colin Montgomerie, the Spaniard's successor as Ryder Cup captain, was three under with three to play, but had a double-bogey six on the 16th. The 47-year-old came back with a birdie for a 70. Kim takes lead In Seoul, teenage amateur Kim Hui-soo shrugged off the nerves of playing in his first professional tournament to take a one-shot lead at the $1 million Maekyung Open Thursday with a first round six-under-par 66. The 19-year-old university student, who was invited to this week's OneAsia event at Namseoul Golf & Country Club in Seoul, chipped in for two of his seven birdies to edge ahead of last year's runner-up Kim Kyung-tae. On a sun-drenched day, Kim Kyung-tae, David Oh, Choi Ho-sung and Cho Min-gyu shared second place, a shot behind the leader as the field prepares for the second round. Kim Yeong-su, Park Sang-hyun and Australia's Ashley Hall posted rounds of 68 to sit well placed at four under ahead of a group of seven players, including 2009 champion Bae Sang-moon, a shot further back.
