Simmonds' debut season as a professional began well, as he recorded back-to-back victories over David McDonnell and Surinder Gill in the British Open, before losing in the third round 2–5 to Jonathan Birch. He could not progress any further than the last 96 in any other tournament, however, and a 5–10 loss to Barry Pinches at this stage of the 2002 World Championship meant he dropped off the tour after only one season.
