Van Peer won two events on the PDC Development Tour in Coventry in April 2015.[2] He went on to finish third in the 2015 Development Tour Order of Merit and was subsequently awarded a two-year PDC Pro Tour card for 2016 and 2017.
Whilst playing at the 2017 Grand Slam of Darts, Van Peer suffered a severe case of dartitis during his match with two time World Champion Gary Anderson. Former player and now Sky Sports pundit Wayne Mardle has talked about his struggles with dartitis and has thrown his support behind the young tyro, even touting him as a future champion despite his struggles with the condition. Despite his visible struggles on stage, Van Peer defeated both Simon Whitlock and Cameron Menzies in the group stage, before losing out to Mensur Suljović in the second round.[7]
