Oldcorn said he wasn’t surprised to see former European No 1 Ronan Rafferty setting the pace on the East Lothian coast after a dazzling nine-under-par 63.
But, at the same time, the Edinburgh man admitted he’d be keeping one eye on Paul Broadhurst, the defending champion and Senior Open title holder, as the title battle unravels over the next two days.
“Ronan is going to be hard to beat as he’s not done himself justice since he turned 50 but I sense he’s worked a lot harder this year and is such a good links player,” said Oldcorn after matching Broadhurst’s opening effort with a 68 to sit joint-seventh. “But, if I can hang around Broady, then I won’t be far away.”
Rafferty, who topped the European Tour money-list in 1989, signed for two eagles and six birdies on the Fidra Links.
