Collin Morikawa set for final round chase: Can he catch Stewart Cink at Harbour Town?

The veteran Cink leads Morikawa by five shots heading into a final round of The RBC Heritage that is a battle of the generations.
Stewart Cink claimed his first PGA Tour win in 1997, a mere four months after Collin Morikawa was born.
25 years ago Morikawa was nothing more than a bump in his mother's tummy, meanwhile Cink was earning graduation to the main tour with three wins on the second tier.

Emiliano Grillo is a stroke back of him in solo third, with Matt Wallace and Sunjae Im sharing fourth on 11-under.
Last week Hideki Matusyama led the Masters at this stage by four and was priced 5/6.
With an extra shot in the bag, Cink is rated a 2/5 shot with Paddy Power who also offer Morikawa at 9/2.

Slipstreaming?
Last year Webb Simpson thrashed a 64 to complete the win here so he knows how to go low with the Sunday pins. Matthew Fitzpatrick and Harold Varner III both currently rank first for Par 4 Performance, alongside Cink. All three are currently tied sixth and eight shots back.
Harbour Town trends
Stewart Cink: 5-shot lead; largest through 54 holes by anyone at this event since Tom Watson in 1979 (8 shots)

Players with a 5+ shot lead through 54 holes on the PGA Tour the last 15 years are 33-for-40 (82.5%) going on to win.
Conclusion
Hefty hitters might want to back Cink at 2/5 with Paddy Power, the rest of us might want to look elsewhere.
Given the frequency of wins from a little further back in the field Simpson 45/1, Fitzpatrick 55/1 and Varner III 125/1 (all at Bet365) might prompt a little interest, but they need to go low and have help.
