Jason Day is set to defend the first of his five titles from last season at Torrey Pines. He'll be joined by another strong field that includes Abu Dhabi winner Rickie Fowler, Phil Mickelson, Patrick Reed, Justin Rose and Dustin Johnson. Here's what You Oughta Know heading into the Farmers Insurance Open. (Stats courtesy Golf Channel research department).
• Day has 10 consecutive top-12 finishes worldwide dating to last year's U.S. Open. He also has more rounds of 63 or better (four) than rounds over par (three) in his last 10 starts.
• Fowler is coming off another impressive win last week in Abu Dhabi. He's won four of his last 18 worldwide starts and moved to fourth in the Official World Golf Ranking, the highest spot of his career.
• In addition to the names listed above, two other players to keep an eye on this week are Brandt Snedeker and Jimmy Walker. Snedeker, who won at Torrey in 2012 and finished runner-up in 2013, is coming off top-3 finishes in his last two starts. He's 34 under in this event in the last five years, the best of any player in that span.
• Walker finished T-10 at Kapalua and T-13 at the Sony Open, and he's 25 under in this event since 2012. He's tied for best record in that span with Snedeker.
• The field is split over Torrey Pines' North and South courses over the first two days, and the South Course will be used over the weekend. The South Course played 3.29 strokes tougher than the North Course last year, and it was the fourth-most difficult on the PGA Tour among non-major championships.
• Over the last 30 years, only two players have more than six top-10s in this event: Tiger Woods and Mickelson. And while Woods (back) won't be teeing it up at Torrey, his insane stats are worth repeating. He's won at Torrey eight times (seven Farmers, one U.S. Open), tying his own record for most career wins at a single course. Woods is also a combined 167 under par in this event since his debut in 1998. That is 74 strokes better in relation to par than any other player in that span.
• Mickelson's record isn't too shabby either. He and Woods are the only players to win this event at least three times, and Lefty has 58 rounds under par in this event in his career, the most of any player in the last 30 years. Scott Simpson recorded 46, while Woods and Mark O' Meara have 44.
