Golf-Watson in clubhouse lead at weather-hit Shenzen

April 20 (Reuters) - American Bubba Watson posted a six-under-par 66 to take a slender clubhouse lead in the opening round of the weather-hit first day of the European Tour's Shenzen International in China on Thursday. South African pair Dean Burmester and Haydn Porteous, Frenchman Gregory Bourdy, Thai Thongchai Jaidee and German Maximilian Kieffer managed to complete their rounds to sit just a shot back before play was called off due to bad light. An hour and 50 minutes of play was lost in the afternoon due to the threat of lightning at Genzon Golf Club. Dylan Frittelli of South Africa was four-under, with Dane Thorbjorn Olesen, Spaniard Eduardo de la Riva and Austrian Bernd Wiesberger at the same score with holes left to complete in their round. After starting on the back nine, two-time Masters champion Watson had a bogey on the 12th but it proved to be the only blemish of his round. After the bogey, Watson fought back with three birdies in the next four holes. Another gain came after making the turn, followed by an eagle on the second. "You know anytime you shoot six-under, shoot in the 60s, you're happy with it but every golfer can pick and choose what they wish they did better, but all in all a great day and a good start," he told the European Tour. "I just made putts today. Most of my swings and most of my shots were really good today and there were no bad swings in there so it just made the score better."
