 It is moving day in Scotland. Third round of the Open in full swing at the Royal Troon Golf Course. And boy, it is raining pretty miserably all day there. Billy Horschel, Daniel Brown share the lead at 5-under. One shot ahead of Xander Shopley and Justin Rose. And second round leader Shane Lowry, he is now tied for fifth. Two shots off the pace. Earlier this morning, South Korea's Siwoo Kim made the longest hole-in-one in Open history when he aced the 238-yard par 3, 17th.
