Newton enjoyed a prolific cricket record while at school and was tipped by The Wisden Cricketer as "one to watch". He made his Northamptonshire first-team debut in 2009. Although born in Taunton, he moved from Somerset at an early age to Norfolk.
He first recalled playing cricket in the back garden aged four or five.
From there he attend Taverham Hall prep school before boarding at Framlingham College in Suffolk. He made his senior club cricket debut for Swardeston in the 2003 season, aged just 13, scoring five runs.
After an impressive schools career which included averaging 94.70 as a 15-year-old at Framlingham and also a double century against the Master Control Console, he was awarded a place on the Northamptonshire Academy in 2005. From there he regularly played for Northamptonshire under-17"s and then from the age of 19, the second XI. Also during this period, he played for England under-17s and captained Master Control Console under-18s.
Newton made his one-day debut for Northamptonshire aged 19 in September 2009 against Middlesex scoring seven.
In 2010 people began to take note of his ability after an impressive performance in scoring his maiden one-day fifty against Essex and decent scores in his debut first-class game against Worcestershire when a lot of others around him failed. He scored his first first-class century against Leicestershire in the final game of the 2010 season. A successful 2011 season saw Newton start to establish himself in the Northamptonshire County Championship first team
In six first-class matches so far he has scored 446 runs at an average of 44.6, with a top score and personal best of 113 coming against Middlesex in August.
These scores see him ranked as having the third highest first-class batting average of his county in 2011, behind only David Murphy and captain Andrew Hall., albeit in fewer matches.
