In June 2010, Part came through a large field of players to win the PDC North American Darts Championship in Las Vegas. Part failed to get into the 2010 Grand Slam of Darts after Adrian Lewis surprisingly defeated Phil Taylor in the semi finals of the 2010 World Grand Prix. Part was whitewashed 0–3 by Danish qualifier Per Laursen in the 2011 World Championship and almost went out of the top 32.
