Having joined Southampton’s academy at nine, Ben Reeves was originally a central midfielder but he developed into a versatile professional, capable of playing full-back or further forward. He eventually broke into the first team early in the 2011-12 season, but promotion to the Premiership meant that his opportunities were limited and he had to be content with being a mainstay of the U-21s, when not on loan in Essex.

During his second loan-spell, he came on as a sub at Wembley, when Southend lost to Crewe in the JPT Final. Released, come the summer of 2013, Ben joined MK Dons on a one-year deal but becoming their Player-of-the Season that year he was smartly offered a two-year extension. Reeves received his first international call-up for Northern Ireland in February 2014, qualifying as his grandparents hail from Fermanagh. He made his debut on 14 October 2014, when he came on as a substitute in a Euro 2016 qualifier match against Greece. In August 2017 he signed for his old MK Dons manager, Karl Robinson at Charlton but two years later he returned to Stadium MK and League One. Released in the summer of 2020 he was invited to join Plymouth on a trial basis and quickly earned himself a contract. After a spell in Kent with Gillingham he returned to Hampshire by joining Eastleigh at the beginning of 2024 and then returned to Staplewood in a player/coach role for the U21s. In 2025 when Tonda Eckert became the interim manager of the first team, Ben became one of his assistants.
