Kenley Jansen had off-season surgery in 2012 to correct a irregular heart beat and he reported to spring training in 2013 ready to go.
What went right
Jansen was magnificent on the mound in 2013, posting a 1.88 ERA in a career-high 75 games, and his 111 strikeouts were the seventh-most by a Dodgers relief pitcher in a single season, and one shy of the major league lead among bullpen arms.
Before 2013, Jansen walked 10.9% of his major league batters faced. This season that dropped to a miniscule 6.2%. He didn't walk a single batter in June, and had a stretch of 18 games and 70 batters from May 23 to June 29 without issuing a free pass. He struck out 28 batters in between walks.
In Game 4 of the NLDS, Jansen struck out the side to give the Dodgers the series win.
What went wrong
In Game 1 of the NLCS, Jansen was brought in to face Carlos Beltran with the bases loaded and no outs, given the circumstances, it didn't look good for Jansen and it wasn't as Beltran got the winning hit. Jansen did finish all five of the Dodger post-season wins, recording two saves in the process.
Kenley Jansen was tendered a contract and is entering his first arbitration-eligible January. Here's a look at what Jansen's contract cost could look like in January 2014.
