Former British Open champion Cameron Smith and Jason Day, back Down Under for the first time in seven years, shot 4-under 67s Thursday and were two strokes off the lead midway through the first round of the Australian PGA at Royal Queensland. Smith, the 2022 British Open champion at St. Andrews, 2015 U.S. PGA Championship winner Day and fellow Australian Marc Leishman were in a group behind first-round early leader Elvis Smylie, the son of former Australian tennis pro Liz Smylie, who shot 65, and Joel Girrbach of Switzerland (66).
