McCloskey finally made his Lakeside debut in the 2010 BDO World Championship after winning one of four places in the Inter-Playoffs in Bridlington. He defeated Steve West in the first round after being 2–1 down in sets. However, he was defeated by Garry Thompson in the second round by 4 sets to 1. Martin has since stopped playing the game he loved so much because he is apparently classed as a professional. Martin was a very good amateur who was lucky enough to achieve his dream and play at Lakeside.
