Kenneth Mackenzie placed two punts - at 150-1 and 66-1 - on Sibley representing England when the opener was a 16-year-old
The family of Dom Sibley have collected £21,000 in winnings after an eight-year-old bet made by the batsman's grandfather came to fruition.
Kenneth Mackenzie placed two punts - at 150-1 and 66-1 - on Sibley representing England when the opener was a 16-year-old.
Though Mr Mackenzie died in 2011, his daughter Christine was able to make the claim on his behalf after the 24-year-old debuted in New Zealand before Christmas.
"He’d have been so proud of Dom’s achievement, so watching him was tinged with sadness, but he’d also have been delighted at pulling off the bet at massive odds," Mrs Sibley told The Times.

Dom Sibley made 133 not out in Cape Town
"Dom was five when he originally said he could play for England — by the time he was seven or eight he was playing for the under nines and that was when the inquiries were made at William Hill about the odds.
"He went back a few years later and told them he thought the odds were a bit skinny, but they honoured the bet."
William Hill in Leatherhead paid out.
A company spokesman said: "This is a record-breaking payout for any such bet involving a cricket protégé.
"Dom clearly made a massive impression on his adoring grandfather and it is a great shame he never lived to collect his winnings."
Sibley made his first international century on Monday, with his second-innings 133 not out putting England in a position of superiority in the second Test against South Africa in Cape Town.
