TROON, Scotland — The British Open brought a final two hours of the worst weather to the world's best players, and Billy Horschel was up for the fight. He survived with a marvelous short game from pot bunkers and the rough, and he managed a 2-under 69 that gave him a one-shot lead going into a final round and his best shot at winning his first major. It was getting there Saturday that was so difficult, a third round that got turned upside down and every other possible way. Masters champion Scottie Scheffler was two behind, one of only two players yet to post a round over par this week. He went from 10 shots behind to playing in the final group Sunday with Horschel, one shot behind.
