His cricketing ability was very clear from an early age and Tom rose rapidly through the Glamorgan age group system, playing for the U17s aged 15, representing the Welsh Minor Counties side aged sixteen and making his full debut in 2007 against Gloucestershire, hitting 71 from 75 balls in a match in the Friends Provident Trophy.
After making his first-class and T20 debuts later that year, Tom continued to grow as a player, making some memorable contributions with the bat and further establishing his reputation as one of the brightest young talents in the game.
He joined Surrey in early 2011, immediately becoming an immensely popular member of the dressing room and quickly establishing himself in the Surrey side for all three formats of the game.
With his natural skill combined with an intense work ethic and his ability to pick things up quickly, Tom impressed throughout his first season at Surrey, scoring an emotional maiden first-class century when the club played Glamorgan in Cardiff.
