Japan's Kohki Idoki takes Senior PGA Championship in 2nd career start LOUIS, May 26 (UPI) -- Kohki Idoki charged ahead after trailing by five strokes Sunday, coming away with the Senior PGA Championship title in just his second tour appearance. The 51-year-old Japanese, a relative unknown on the Champions Tour circuit, sank a long birdie putt on the 17th en route to a sterling round of 6-under-par 65 at Bellerive Country Club. He ended at 11-under-par 273, two strokes ahead of the field in notching his first-ever major championship. Third-round leader Kenny Perry (72) was ahead by as many as three strokes Sunday but fell short in his bid for a third career title after carding a double-bogey on No. 5 and then stumbling to two more late bogeys. He was joined in second place by Jay Haas (70) at 9-under 275. Sole possession of fourth at minus-8 went to Mark O'Meara (65) while Kiyoshi Murota (67) took fifth at 7-under.
