Australian Cam Davis has conjured some magic to capture a share of the first-round clubhouse lead at the PGA Championship in North Carolina. Davis sparkled with a five-under-par 66 to enjoy top spot on the leaderboard at men’s golf’s second major of the year with unheralded American Ryan Gerard. As Masters champion Rory McIlroy quickly found himself on the back foot in his quest to follow up his historic Augusta triumph with a fifth victory at Quail Hollow, Davis rolled in seven birdies on Thursday (Friday AEST). Davis had hold of solo top spot until stumbling late with a bogey at the treacherous par-5 ninth, his last hole of the round after starting on the 10th.
