One year into his major league career, Johnson was traded to the Mariners. He intimidated teams like the "California Angels" (whom he's shown pitching against in Anaheim in 1990) with his impressive height and angry expression.
A pitch with teeth
Johnson's pitches were always energetic — and sometimes out of control — in his early career. So much so that while pitching against the Texas Rangers in 1992, he managed to jar loose a dental fixture!
A different kind of strike
The 1994 season went well for Johnson (here pitching against the A's) but his stride was cut short by a strike.
This isn't the little leagues
During his career, Randy Johnson has been selected for the All-Star game 10 times, including his 1995 turn as the AL starting pitcher against NL starting pitcher Hideo Nomo. Johnson was the AL strikeout leader from 1992-95.
By 1995, Johnson was a force to contend with. The Mariners won this game against the Texas Rangers in Arlington by a landslide. Johnson went on to lead the AL in ERA and capture the Cy Young award.
At the 1997 All-Star Game in Cleveland, Randy Johnson must have felt at home as he chatted with Baltimore Orioles' Mike Mussina in the outfield. After all, it was his fifth time being selected as an AL pitcher for the event.
Something to celebrate
Johnson went eight innings and struck out 11 Angels to lead his team to a 4-3 victory that clinched the American League West title for the Mariners in 1997.
Mid-season in 1998, Johnson was traded to the Houston Astros, who were in the running for the pennant. He went 10-1 in 11 starts, and the Astros reached the playoffs in the only season he pitched for them.
In 1999, the free agent signed with a new team, the Arizona Diamondbacks. The left-hander won the NL Cy Young award that year and again in 2000, 2001 and 2002, all four years with the same fledgling team. He became only the second player in major league history to win the prestigious award in both the American and National Leagues.
Racking up honors
In 2000, not only did Johnson win the NL Cy Young award, he also was named Most Outstanding Pitcher at the Players Choice Awards.
Talk about explosive pitching — a pitch Johnson threw at spring training in 2001 struck out an unlucky dove. There was a burst of feathers, and the bird died on impact.
Bringing the heat
The 6-10 pitcher generated enough velocity with his long frame to throw 100-mph fastballs at times during his prime. Here he delivers a pitch against the Los Angeles Dodgers in L.A. in 2001.
2001 also marked the year Johnson became a World Series champ, leading the Arizona Diamondbacks to victory as a co-MVP. And the fans got behind Johnson's performance, showing their faith with strikeout signs during the World Series.
Pair of aces
The Diamondbacks won the 2001 World Series four games to three against the New York Yankees to become the world champions. Johnson was named co-MVP along with pitcher Curt Schilling.
Sock it to him
Heavyweight boxing champion Lennox Lewis presented Johnson and Schilling with Sportsmen of the Year trophies in 2001 courtesy of Sports Illustrated, adding to the pitching duo's World Series recognition.
Tip your hat
Big Unit struck out Reggie Sanders in 2002 to collect his 3,500th career strikeout. That year he'd take the pitching Triple Crown, leading the National League in wins, ERA and strikeouts.
On top of his game
The dynamite pitcher continued to wow in 2002, the year he pitched against the St. Louis Cardinals in the National League Division Series. It was also the year he'd win his fourth consecutive Cy Young award, marking the fifth time he'd won the award a record second only to Roger Clemens.
Perfect at 40
On May 18, 2004, Big Unit threw his first perfect game while pitching for the Arizona Diamondbacks against the Atlanta Braves. He was 40 years old, making him the oldest pitcher to do so and only the 17th.
Trying on pinstripes
In 2005, Johnson was traded by the Diamondbacks and introduced as the newest Yankees pitcher.
Johnson's pitching suffered in 2005-06 while he was with the Yankees, and at the end of the 2006 season it was revealed that he had a herniated disc that had been affecting his performance.
Back to the desert
After his two rocky seasons with New York, Johnson returned to the Diamondbacks in 2007, after requesting a trade in preseason after the death of his brother. In Phoenix, the pitcher could be closer to his family.
Still bringing it
At the end of 2008, Johnson signed with the Giants, for whom he's still pitching as the second starter in the rotation.
