Last month, Randy Johnson became the first player inducted into the Hall of Fame with a Diamondbacks cap on his plaque. On Saturday, Johnson became the third player to have his number retired by Arizona.

The D-Backs retired No. 51 in honor of Johnson during a pregame ceremony Saturday evening. He walked in from the Chase Field bullpen and received a huge ovation, and later played the drums. Here's the entire ceremony:

Johnson, now 51, played with the D-Backs from 1999-2004 and 2007-08. He helped the club win the 2001 World Series title and won four of his five Cy Young awards with Arizona.

The D-Backs signed Johnson to a four-year, $52 million contract during the 1998-99 offseason, and it is arguably the most successful free agent pitching contract in history. During those four seasons the Big Unit went 81-27 with a 2.48 ERA (187 ERA+) and 1,417 strikeouts in 1,030 innings. He racked up 38.3 WAR and won the Cy Young all four years.

All told, Johnson went 118-62 with 2.83 ERA (164 ERA+) and 2,077 strikeouts in 1,630 1/3 innings with Arizona. He is the franchise's all-time leader in pretty much every meaningful pitching category. Wins, ERA, strikeouts, innings, WAR, you name it.

Johnson played eight of his 22 big league seasons with the D-Backs. He won 303 career games overall and ranks second all-time in strikeouts (4,875) and ninth in WAR (104.3).

No. 51 is the third number retired by the D-Backs, joining No. 20 for Luis Gonzalez and the universally retired No. 42 for Jackie Robinson.
