Son Nick, 16, who plays off nine, was first to shine when he achieved the feat on the 220-yard, par-three fifth at his home club, Bush Hill Park.
He said: “On the fourth hole I had a quadruple eight, which made me so angry that I was just going to step up and hit the ball on the fifth. However, I managed to calm down a bit on the tee, while waiting for my turn to tee off.
“I took my shot seriously and managed to strike it perfectly – a slight right draw on line with the pin – and my playing partner said ‘that’s in the hole!’. I celebrated like I’d just won the Masters.”
And, just eight months later, father Kevin, 48, followed in his footsteps while they were playing together, as they often do, when he too sank an ace on the fifth.
12-handicapper Lewis senior said: “Traditionally I always play a driver on this hole, but Nick insisted a three-wood was fine.
“I tried the three-wood and, fortunately, hit a shot which looked good, but the pin was behind bunkers so we had no idea how good the shot actually was.
“It was only after searching for my ball at the front and back of the green that Nick looked in the hole and found my ball. The celebrations started there – I only managed to score one more point after that hole, but didn’t really care.”
Lewis senior has been fortunate to have had two previous holes-in-one since taking up golf – he achieved his first when he was 16 and his second five years ago – while Nick’s, last year, was his first.
Kevin added: “I must confess I was totally in shock: firstly to get the hole-in-one on the same hole as Nick, and secondly to have achieved it on such a prestigious day as captain’s day.
“I have been playing golf for 35 years and Nick has been playing for five years. I get to play most weekends and Nick now plays at least three times a week, hence why his handicap is far better than mine.”
And next time they challenge each other to a game they’ll have no excuse for missing their tee-time, as both received limited-edition BOSS watches to recognise their achievements.
