LOS ANGELES – Some tidbits to whet your appetite for Sunday's final round of the Northern Trust Open at Riviera.

• Phil Mickelson, tied with Keegan Bradley for the lead, is a pretty good closer, winning 21 of 30 times when he has led, or shared the lead, after 54 holes. He has won his last three when doing so.

• Mickelson and Bradley will be in the same grouping with Bryce Molder in the last threesome off on Sunday. Mickelson and Bradley have become pals, often playing practice rounds together. They share the same management company. Last year, Bradley even helped Mickelson tinker with a belly putter.

• Mickelson will be working Sunday to complete his eighth consecutive round under par. That goes back through his AT&T Pebble Beach National Pro-Am victory.

• If Mickelson wins, it will be the fourth time he has won back-to-back PGA Tour events, his last coming in 2006 (BellSouth Classic/Masters).

• If Mickelson wins, he’ll join Arnold Palmer and Ben Hogan as three-time winners in this event. Lloyd Mangrum and Macdonald Smith each won it four times.

• Nobody has won PGA Tour events in back-to-back weeks since Tiger Woods won the Buick Open and WGC-Bridgestone in 2009.

• Americans have won the first six PGA Tour events of the year. The top five on the leaderboard are all Americans.

• Ten players are within three shots of the lead.

• Winners of the last three PGA Tour events have come from at least six shots behind. A guy six shots back this week will have to pass 19 players to win.
