Byeong Hun An leads the Waste Management Phoenix Open after 54 holes, but he’s he'll have to fend off a host of challengers to claim his first PGA Tour victory. Here’s what You Oughta Know for Sunday at TPC Scottsdale.
• Recent history is not on An’s side, as six of last seven winners at this event trailed entering final round.
• The last two winners of this event were three shots back entering Sunday. Luckily for An, no one is three back, although the defending champio, Hideki Matsuyama, is four behind.
