The 27-year-old Australian, who claimed his first Major title at the PGA Championship just a few weeks ago, was in a league of his own at Conway Farms Golf Club, to the north of Chicago – and this despite the world-class field at the third of the four Playoff tournaments being restricted to the top 70 players in the FedExCup. Day's victory, which earned him a cool $1.485 million, also saw him replace Northern Ireland’s Rory McIlroy (-14, T4) at the top of the world rankings.
