A crowded leaderboard at the RBC Heritage largely thinned Saturday, as several players were able to tame Harbour Town Golf Links during the third round. Here's what You Oughta Know heading into Sunday's final round, where Charley Hoffman holds a two-shot lead over Webb Simpson:
• Simpson, the defending U.S. Open champion, isn't the only former Open champ nipping at Hoffman's heels. Graeme McDowell, who won the Open in 2010, is tied for fourth, four shots back. Simpson has not won since his Open triumph, while McDowell has taken the European Tour's 2010 Andalucia Valderrama Masters and the unofficial 2010 and 2012 World Challenge.
• The fact that Hoffman rode a hot putter to the top of the leaderboard Saturday should be no surprise, as Harbour Town's small greens have yielded some of the fewest putt totals in PGA Tour history. Eight years after David Frost set a Tour record with 92 putts for four rounds at Hilton Head, Hoffman needed only 21 putts to complete his 5-under 66 Saturday, and through three rounds has taken just 73 strokes on the greens of Harbour Town.
• Though he has yet to win in 2013, Bill Haas has arguably been among the more consistent players on the PGA Tour this season. The 2011 FedEx Cup champ has already notched five top-10 finishes in 10 starts this year, tying him with Keegan Bradley and Brandt Snedeker for the most top-10 finishes on Tour. Beginning the final round tied for sixth, Haas has an opportunity to pass both Bradley and Snedeker in the category with another high finish at Hilton Head, and can perhaps grab his first win since the 2012 Northern Trust Open in the process.
• While Brendon De Jonge continued his recent trend of playing well during the third round at Harbour Town, he has yet to carry that form forward into the final round. The Zimbabwean, among the top players still without a PGA Tour win, shot a 4-under 67 Saturday, the third time in five Hilton Head appearances that he has shot 67 or better during the third round. He has yet to break par in the final round, though, averaging 73 shots in his four prior starts. De Jonge will begin Sunday tied for fourth, four shots behind Hoffman, hoping to end his recent stretch of final-round disappointment along the Calibogue Sound.
• Both playing this year on one-time career money-list exemptions, Jerry Kelly and Stuart Appleby are in position for their highest finishes of the season at Harbour Town. Kelly, who fired a bogey-free 66 Saturday, will begin the final round tied for sixth, still seeking his first top-20 finish of the 2013 season. Appleby, meanwhile, starts the final round in a tie for 14th at 5 under, with his tie for 46th at the Valero Texas Open earlier this month still currently serving as his best finish on Tour this year.
• Of the 22 players who barely made the 36-hole cut thanks to Jesper Parnevik's missed putt early Saturday morning, 14 were able to survive the 54-hole cut that trimmed the field from 91 to 71 players. No one improved their position more than James Hahn, Trevor Immelman and Ben Crane, all of whom played their way from the cut line into a tie for 23rd after rounds of 5-under 66. Ironically, one of the eight to fall victim to the MDF label Saturday night was Parnevik, who struggled to a 2-over 73 after missing a short putt Saturday morning that could have sent all of the players at 2-over 144 home for the weekend.
• After a 4-under 67 Saturday, Ryo Ishikawa appears poised for his highest finish on the PGA Tour in nearly a year. Ishikawa, who finished second at the Puerto Rico Open last March, has made only four cuts in 10 prior starts this season on the PGA Tour, and has not recorded a top-25 finish since the Memorial last summer. The Japanese sensation enters the final round among a large group tied for sixth at 6 under, five shots off the pace, hoping for another low round that may bring with it his first PGA Tour victory.
