Kenley Jansen racking up strikeouts at historic rate

6 Comments

Last season Carlos Marmol set the all-time record by striking out 16.0 batters per nine innings, becoming the first pitcher in baseball history with a strikeout rate above 15.0.

Marmol’s record is probably safe, but Dodgers reliever Kenley Jansen looks set to join him in the 15-plus club. Last night Jansen closed out a 3-2 victory for his fourth save of the season and struck out the side in the process, giving him 83 strikeouts in 48 innings overall.

That works out to 15.6 strikeouts per nine innings, which is the second-highest rate of all time:

                  YEAR     SO/9
Carlos Marmol     2010     16.0
KENLEY JANSEN     2011     15.6
Eric Gagne        2003     15.0
Billy Wagner      1999     15.0
Brad Lidge        2004     14.9

Predictably the top five spots all belong to relievers from the past 15 years. In terms of strikeout rates for starting pitchers Randy Johnson has the all-time record with 13.4 in 2001, when he whiffed 372 batters in 250 innings for the Diamondbacks.

Jansen, who began his pro career as a light-hitting catcher and didn’t move to the mound until 2009, has a 2.28 ERA, .156 opponents’ batting average, and 124 strikeouts in 75 innings as a big leaguer.

Infielder Trevor Plouffe has signed a minor league deal with the Phillies, Gerry Fraley of the Dallas Morning News reports. Plouffe asked for and was granted his release from the Rangers earlier this month.

Plouffe, 31, had a double and a home run in 17 plate appearances with Triple-A Round Rock to start the 2018 season. He spent last year with the Athletics and Rays, putting up a meager .198/.272/.318 batting line in 100 games.

Plouffe has mostly played third base throughout his career, but can also handle the other three infield spots and both outfield corners, so he’ll serve as organizational depth at Triple-A Lehigh Valley for the Phillies.
