Dominic Sibley became the youngest player to make a double century in the County Championship in 2013 when he grandly repelled Yorkshire's attack at The Oval in only his third first-class match.

Sibley developed through the Surrey youth system while at Whitgift School on a sports scholarship. At just 15 he made his Surrey 2nd XI debut, scoring 37 against Sussex at Horsham. That summer he made a double century for his club side, Ashtead. For the next two seasons he developed under the tutelage of Surrey academy director Gareth Townsend. He was selected for England Under-19s tour of South Africa in the winter of 2012-13 and made a century in the second Youth Test.

Sibley's Surrey bow came in a Yorkshire Bank 40 against Essex at The Oval at the start of August. It was memorable for the wrong reason as was stretchered off with a badly gashed knee having dived to make his ground and got his pad stuck in the ground. The injury ruled him out of England Under-19s tri-series but he returned to the Surrey first team at the end of the month, making a duck against Warwickshire at Edgbaston.

Instead of returning for his final year at Whitgift, he played the final three matches of the 2013 season. After failures against Somerset at Taunton and then back at Edgbaston, he etched his name into the record books with 242 against Yorkshire at The Oval. It was the highest maiden century for Surrey and the second-youngest double century by an Englishman in first-class cricket, only WG Grace being younger.

Amid the gloom of Surrey's relegation, Sibley was a rare source of pride. Much, possibly too much, was expected of him in the next two seasons, when he was still a teenager. He managed only a dozen games in two years and was not a central part of a fast-improving Surrey squad, but few at the club doubted that he would return and prove that his innings against Yorkshire was no one-off.

There were signs of consolidation in 2016, a season in which he came painfully close to an elusive second Championship hundred. Against Hampshire at the Ageas Bowl, he reached 99 before he was bowled by Gareth Berg. Perhaps surprisingly, he revealed signs of a more expansive game when he topped Surrey's Twenty20 averages.

Perhaps unsettled by Surrey's decision to sign Mark Stoneman and Scott Borthwick as top-order competition at the end of 2016, he surprised the club by turning down a new three-year contract during the 2017 season and instead signed a three-year deal with Warwickshire. With some frustration on both sides, he was allowed to leave in August on a loan deal which saw Rikki Clarke move in the opposite direction and quickly established himself at the top of the order in the red and white ball teams.
