(Reuters) - American Jay Haas charged into early contention for a third Senior PGA Championship title by shooting a flawless five-under-par 66 in Thursday's opening round at Bellerive Country Club in St. Louis, Missouri.
The 59-year-old shrugged off lingering back pain with accurate driving and deft course management to end a cool, blustery day tied at the top with compatriot Duffy Waldorf, who qualified for the over-50 Champions Tour last August.
