I wrote last week about how Kenley Jansen had the second-highest strikeout rate in baseball history, but the Dodgers rookie was so dominant down the stretch that he vaulted into the top spot.
Jansen ended up striking out 34 of the final 56 batters he faced this season–which is absolutely ridiculous–and finished the year as the first pitcher in baseball history with more than 16.0 strikeouts per nine innings.
Here’s the new all-time leaderboard (among pitchers with at least 40 innings):
YEAR SO/9 KENLEY JANSEN 2011 16.1 Carlos Marmol 2010 16.0 Eric Gagne 2003 15.0 Billy Wagner 1999 15.0 Brad Lidge 2004 14.9
Jensen racked up 96 strikeouts in 53.2 innings while posting a 2.85 ERA and .159 opponents’ batting average. Not bad for a 23-year-old rookie who was a light-hitting catcher in the minors as recently as two seasons ago.
