Triples is a relative newcomer with the first State Championships coming in 1968. After a 14 season break between 1991 and 2004 the Triples is back and cut throat as ever. Poor ends will often see big scores go the other way in this form of the game. Dennis Katunarich is the only man to win the event playing every position. He and Robbie Ball are also the only players to win back to back State Events 15 years apart.
