• Keith Young back with a bang at Glencorse
Keith Young won the Glencorse club championship after shaking off the rust to produce an incredible performance in the final.
Although he’d played no competitive golf for a couple of years, Young hit eight birdies and no bogeys in the opening round of the 36-hole title decider.
Despite shooting 66, opponent Jamie Morris found himself ten down and, though he pegged Young back a bit after lunch, eventually succumbed 5&4.
“I have played at Glencorse for nearly 60 years but seen nothing like it,” said Peter Lamb. “Keith is clearly still a class act.”
Stephen Lamb shot 63-62 to win the qualifiying but went out in the first round.

Other winners were Brendan Dick (seniors), Murray Cannon (juniors), David Duthie (gents’ B) and Hazel Carpenter (ladies’ B).
