The Arizona Diamondbacks will retire Randy Johnson's No. 51 this year, team CEO Derrick Hall told reporters Tuesday.

Johnson, who was announced as a 2015 inductee into the Baseball Hall of Fame on Tuesday, was also named a special assistant to the team's president and CEO.

Johnson played eight seasons with the Diamondbacks, from 1999 to 2004 and again from 2007 to 2008. He had a 118-62 record with 2,077 strikeouts in 233 games for Arizona. He and Curt Schilling helped lead the Diamondbacks to a World Series championship in 2001.

Johnson threw a perfect game at the age of 40 on May 18, 2004, the only perfect game in franchise history.

Only one other Diamondbacks player has had his number retired by the franchise. The team retired Luis Gonzalez's No. 20 in 2010.
