Johnson's 303 career victories are the fifth-most by a left-hander in MLB history, while his 4,875 strikeouts place him second all time behind Nolan Ryan and first among left-handers. Johnson is a ten-time All-Star, won the Cy Young Award five times, and is one of only two pitchers to win the award in four consecutive seasons (1999–2002). Johnson won Cy Young Awards in both leagues. He is also one of five pitchers to pitch no-hitters in both leagues, and one of 20 pitchers in history to record a win against all 30 MLB franchises.
Johnson enjoyed a career longevity uncommon to pitchers, with his signature fastball-slider combination remaining effective well into his 40s. Four of his six 300-strikeout seasons occurred after his 35th birthday. On May 18, 2004, at 40 years old, he threw Major League Baseball's 17th perfect game, and remains the oldest pitcher to accomplish this feat. Johnson ultimately retired at the age of 46, and was elected to the Baseball Hall of Fame in 2015, his first year of eligibility. He is the first member of the Hall to be depicted in a Diamondbacks uniform on his plaque.
