Russell Knox living the dream at Wentworth

Scotland’s Russell Knox believes he can make the leap from a former “head case” to a bona fide superstar as he targets a Ryder Cup debut in 2016.

Knox is relatively unknown on the European Tour after leaving his native Inverness to attend Jacksonville University on a golf scholarship, but his runners-up finish in the Irish Open on Sunday elevated him to a career-high 23rd in the world.

That and his victory in the WGC-HSBC Champions in Shanghai last November also means there is a 60ft poster of Knox draped on the grandstand behind the 18th green at Wentworth, where the 30-year-old will make his debut in the BMW PGA Championship this week.
