 I'm Joey Waller. Right now, they open in rainy Troon, Scotland. The leader, 29-year-old Englishman Daniel Brown. His first major championship, Billy Horschel, 5-under through 17. Meanwhile, five others are two shots behind. Sewu Kim with a hole-in-one on the par 3 17th today at 238 yards. That's the longest ace in open history.
