Rory McIlroy, his US Open title defence a fortnight away, missed the cut in his third straight tournament on Friday, heading for the exit early at the USPGA Tour's Memorial.
The 23-year-old star from Northern Ireland had regained the world number one ranking four weeks ago but has since missed the cut at the US tour's Players Championship and Europe's BMW PGA Championship at Wentworth.
McIlroy's seven-over 79 included two double-bogeys -- a seven at the par-five 11th hole and a six at the par-four 14th.
He had three bogeys and not a single birdie on the day, his six-over 150 well beyond the projected cut as the round was coming to a conclusion.
McIlroy had already added next week's St. Jude Classic in Memphis to his schedule, saying he wanted to get more rounds in before the US Open tees off at Olympic Club in San Francisco on June 14.
