At the 2010 Grand Slam of Darts, Waites once again reached the final by winning all three of his group matches, then following up with comprehensive victories over Raymond van Barneveld, Co Stompé and Steve Beaton (who had earlier eliminated Taylor). Waites played James Wade in the final, and defeated the PDC world #2 16–12 having trailed 8–0. The win was Watites's first in either a PDC or a BDO major, and made him the first player from the BDO (and the first player from either code other than Phil Taylor) to win the Grand Slam.
