England's Ross McGowan overshadowed world No. 1 and defending champion Luke Donald to take a one-shot lead after the opening round of the Madrid Masters Thursday. One shot behind are Australian Brett Rumford and local favorite Gonzalo Fernandez-Castano, who thrilled the home fans until a three-putt bogey at the final hole cost him a share of the overnight lead. Donald carded a 68 to be four shots off the pace. Yang leads in SK Defending champion Y.E. Yang and American Rickie Fowler set the first round pace at the Kolon Korea Open Thursday with US Open champion Rory McIlroy just one shot off the pace. In an eventful first round, 2010 US PGA Tour Rookie of the Year Fowler carded a four-under-par 67 before South Korea's Yang matched the American's tally in the OneAsia event, despite being forced to battle increased winds. World No. 3 McIlroy carded seven birdies but twice found the water on his way to a 68. He sits tied for third at three under alongside South Korea's Hong Soon-sang and Hong's amateur compatriot Lee Soo-min. “I birdied the first hole of the day and that helped lot. I played well and enjoyed the round,” said Yang, who overcame a 10-shot final round deficit last year to win a second Kolon Korea Open title.
