The Top 20 Pitching Seasons in the Last 25 Years

T7. Randy Johnson, Arizona Diamondbacks (1999)

In case you're already tired of seeing Johnson's name, sorry. Just four years later, Johnson turned in a 17-win season with a WAR of 9.5 once again, this time on a FIP of 2.76 in 35 starts.

Once again, Johnson was named the NL Cy Young winner and rewarded with a spot in the All-Star game.
