Some notes and nuggets to whet your appetite for Sunday’s final round of the RBC Heritage:
• Carl Pettersson knows how to close the deal when he’s in position to win a PGA Tour event. He has led or shared the lead going into the final round in three of his four PGA Tour victories. Overall, Pettersson has won three of the five times he has held or shared the 54-hole lead in a PGA Tour event. His Tour titles: ’05 Chrysler Classic, ’06 Memorial, ’08 Wyndham Championship, 2010 RBC Canadian.
• Colt Knost, a shot behind Pettersson at Harbour Town, forfeited his invitation to the 2008 Masters after winning both the U.S. Amateur Public Links and U.S. Amateur in ’07. He decided to turn professional instead of playing the Masters as an amateur. Knost still hasn’t earned back that invite to Augusta National, but he’ll get one if he wins Sunday at Hilton Head.
• Knost’s best finish in a PGA Tour event is a tie for third at the Mayakoba Golf Classic in late February. It is his only top-10 finish in 66 PGA Tour starts as a pro.
• Pettersson is No. 68 in the Official World Golf Ranking, Knost No. 366.
• Zach Johnson tees it up Sunday four shots off the lead, looking to win his eighth PGA Tour title. Nobody in the top 10 of the RBC Heritage leaderboard has won more PGA Tour titles than Johnson.
• Brandt Snedeker starts Sunday six shots behind, the same deficit he faced when he came from behind to win this event a year ago. Snedeker has a history of big comebacks, winning all three of his PGA Tour titles in that fashion. He was seven behind starting the final round when he won the Farmers Insurance Open in January. He was five back going into the final round when he won his first PGA Tour title, the Wyndham Championship in ’07.
• This is the season of the big comeback. So far in ’12, winners have overcome deficits of seven (Snedeker/Farmers Insurance Open), eight (Kyle Stanley/Waste Management Phoenix Open), six (Phil Mickelson/AT&T Pebble Beach National Pro-Am) and seven (John Huh/Mayakoba Golf Classic).
• Bubba and Boo in back-to-back victories for the Blackwater River Region? A week after Bubba Watson won the Masters, Boo Weekley enters the final round in fourth place at the RBC Heritage. He is five shots off the lead. Watson and Weekley both grew up in the Florida Panhandle, both grew up playing at Tanglewood Country Club in Milton, Fla., and both attended Milton High School, though Weekley is five years older. Weekley is a two-time RBC Heritage winner.
• Barring a torrid final round, the PGA Tour will feature a new world No. 1 come Sunday night with Rory McIlroy expected to move up. To prevent that, current No. 1 Luke Donald must finish tied for eighth or better at Harbour Town. Donald starts Sunday tied for 52nd and seven shots behind the current group tied for eighth.
