BURGHILL Valley professional David Park is hoping for a return to form as he bids to get back among the top echelon of the European Tour. Today he competes in the Loch Lomond World Invitational where the top 15 non-exempt finishers are guaranteed a start in the 130th Open Championship at Royal Lytham and St Anne's next week. Failing that, his only chance of playing in the Open is through the final qualifying competitions which take place on Sunday and Monday.
