Kenley Jansen broke the all-time strikeout rate record

6 Comments

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.

Tuesday’s Rays-Orioles game postponed due to rain

The Orioles announced that Tuesday night’s game against the Rays at Camden Yards has been postponed due to rain. The game will be made up as part of a single-admission doubleheader on May 12 at 3:05 PM. The second game will begin about 30 minutes after the first game finishes.

As Weather.com noted recently, Major League Baseball has already seen a record number of weather-related postponements this month, at least dating back to 1986.

According to Jayson Stark of The Athletic, as of April 19 when he wrote this column, there had been only four days where all 30 teams managed to play on the same day. Stark also pointed out that, at the time he published his article, there had been 27 games with first-pitch temperatures in the 30’s. There was one such game last year, eight in 2016, four in 2015, and 12 in 2014. It’s been a weird month.
