CHARLOTTE, N.C.: Jordan Spieth came to Quail Hollow hoping to follow in Rory McIlroy’s footsteps and complete the career Grand Slam. After Thursday’s opening round of the PGA Championship, he’d probably be happy just to make the cut. The 31-year-old Spieth struggled in every facet of the game at demanding Quail Hollow — off the tee, with his approach shots, his chips and even his putting — and shot a 5-over 76, leaving him 12 shots behind leader Jhonattan Vegas and all but ending his hopes this year of capturing the one major that has eluded him since he turned pro 13 years ago. Spieth could never find his swing and repeatedly misjudged distances to the flag, leaving him scrambling for par all afternoon. He managed to hold it together early and was even par through eight holes. Then the wheels came off. He bogeyed six of of the final 10 holes — chunking a chip from the rough on No. 11 and failed to get up and down for par on No.
