Who were the winners and losers on Sunday at the PGA Championship? Let's take a closer look with another edition of birdies and bogeys

Birdie: Rory McIlroy

At Congressional, the question was how McIlroy would hold up given his recent collapse at the Masters. This week, the questions were about a dismal summer stretch that rendered him irrelevant in the two previous majors. In each case, McIlroy has provided a resounding answer. McIlroy's display over the final 36 holes at the Ocean Course was no less impressive than his U.S. Open win at Congressional, both a product of remarkable ball-striking and timely putting. With the win, McIlroy takes over the No. 1 spot in the world ranking, and becomes the first player from the U.K. since Tommy Armour 1930 to win the PGA. Surely, as Tiger Woods has shown, McIlroy will face more tests in the years to come. But thus far he's shown an ability to respond.
