Whatever the reason for all the whiffing, Carlos Marmol led all MLB relievers last season with 114 strikeouts. Joel Hanrahan was second with 93, while Brad Lidge, Octavio Dotel, and J.P. Howell rounded out the top five with 92. Marmol's season total is definitely impressive, not only because he outpaced everyone by twenty, but also because it's the most relief strikeouts since 2004. His total isn't anywhere near the record for most strikeouts in relief, however.
A pitcher has reached 120 strikeouts in relief in a single season thirty-six times. Some of those pitchers, like Mike Marshall or Goose Gossage, got there by throwing a ton of innings in relief. Some pitchers, like Billy Wagner, got there by striking out a ton of batters per nine innings. The rest were obviously a healthy mix of those two extremes. Whatever method got them there, the list of pitchers is below:

Students of baseball history may recognize the significance of the season behind Mike Marshall's highest appearance on the list. That was the year he pitched 208 1/3 innings over a major league record 106 games. He only struck out six batters per nine innings, but the sheer number of innings pitched allowed him to rack up K's. Meanwhile, Eric Gagne, Billy Wagner, and Brad Lidge made up for pitching fewer innings by striking out just under fifteen batters per nine innings.
And now for something completely different: students of ridiculous baseball videos may recognize Mark Littell, also known as the guy who enjoys proving athletic supporters work.
