Every pitcher with 300 strikeouts in a season is part of an elite club. Throughout the history of MLB, only 19 pitchers have accomplished the amazing feat of striking out 300 batters in a season. Most of the pitchers on this list are among the best pitchers in the history of the sport, and they were all — for either a season or their entire careers — among the top strikeout pitchers.
Pitchers like Randy Johnson and Sandy Koufax are synonymous with strikeouts, and of course, Nolan Ryan, who holds the record for most strikeouts by a pitcher in a season and a career, has six 300-strikeout seasons. Astros teammates Gerrit Cole and Justin Verlander joined the ranks in 2019 with career years and are among more recent pitchers such as Clayton Kershaw and Chris Sale to strike out 300 batters.
