AUGUSTA, Georgia (Reuters) - Australian Marc Leishman regained the Masters lead in the second round on Friday while the tournament's feel-good story took an unfortunate turn when 14-year-old Guan Tianlang was penalised for slow play.
Leishman, the overnight leader after an opening 66, remained at six under par after birdies at the seventh and eighth holes made up for two earlier bogeys for a one-shot lead over veterans Fred Couples and Jim Furyk and a charging Tiger Woods.
