The selection committee announced on a conference call Tuesday it had elected the maximum four players this year. All were eligible for the first time.
Yzerman retired in the summer of 2006 with the sixth-highest point total in NHL history. The longtime Detroit Red Wings captain won the Stanley Cup three times and a gold medal with Canada in the 2002 Olympics.
Hull's 741 goals rank third all-time, Robitaille's 668 are the most by a left wing and Leetch is one of just five defensemen to have a 100-point season.
A player must be retired for three seasons before becoming eligible to enter the Hall. The induction ceremony will be Nov. 9.
