Jordan Spieth and Rory McIlroy headline this week's Northern Trust Open at one of the toughest courses on Tour – Riviera Country Club. Here's what You Oughta Know entering the event (stats courtesy Golf Channel research department):
• Spieth missed that playoff by one stroke last year, but the world No. 1 is back and making his fourth start in this event.
• Spieth has plenty of history at Riviera. He led Texas to the NCAA Championship on this course in 2012, and he's a combined 13 under par the last two years at the NTO. That ranks third behind D. Johnson and Bubba Watson, who are also in the field this week.
• Spieth has finished first or second in 14 of last 33 worldwide starts.
• Someone who doesn't have any history at Riviera is McIlroy, who is making his debut at the Northern Trust Open.
• It's McIlroy's first start in the United States since the Frys.com Open in October.
• McIlroy has 11 PGA Tour wins since 2010; most of any player during that span.
• The world No. 3 will be tackling one of the toughest courses on Tour. Riviera had the most difficult greens to hit in regulation last season.
• Riviera also ranked as the toughest course to make putts inside 10 feet last season.
• Sergio Garcia also missed the playoff last year by a stroke. He tied for seventh in his only worldwide start this year at the Qatar Masters.
