You Oughta Know: WMPO tough on 54-hole leaders


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.

• An would be in good company if he does get the victory tomorrow. The only 54-hole leader to win since 2010 was Phil Mickelson in 2013.

• An is making his Waste Management Phoenix Open debut this week. He would be the fourth to win in his debut at TPC Scottsdale.
