Top-ranked defending champion Jason Day, battling illness and fatigue, birdied the par-4 11th hole Thursday at Baltusrol for a solid start to his repeat bid at the 98th PGA Championship. McIlroy opened with three pars while Mickelson began bogey-par-par after finding a greenside bunker at 10 and missing a seven-foot par putt. Defending champion Day has struggled with illness and taken extra rest in the run-up to the year's final major tournament, playing only one practice round on the eve of the event at an unfamiliar course.
