(Reuters) - Kim Si-woo made his 38th start on the PGA Tour a winning one when he clinched a commanding five-stroke victory at the Wyndham Championship in North Carolina on Sunday. An hour-plus rain delay with two holes left merely postponed Kim's celebration at Sedgefield Country Club in Greensboro. Kim, 21, is the second South Korean to win in Greensboro, 11 years after his mentor K.J. Choi.
