Kenley Jansen’s Dominant Fastball
Every year it seems we hear about a former position player trying to transition to the mound in order to save his professional career.
Two years ago, it was Tony Pena Jr. with the Royals who moved from a light-hitting shortstop to reliever. In 2010, Sergio Santos of the Chicago White Sox grabbed headlines after making the big leagues as a shutdown reliever after struggling for a better part of a decade as a shortstop. Trevor Hoffman also failed as a shortstop before trying his luck as a pitcher. Carlos Marmol played two years as a catcher and outfielder for the Cubs before stepping foot on the mound for good.
It’s not uncommon. One can set foot in a big league bullpen and likely find a former position player lurking in that group — a player that just couldn’t cut it as a professional ballplayer at their respective positions — but the organization saw a special arm they wanted an opportunity to refine on the mound.
In 2011, the position-player-turned-reliever that firmly burst onto the scene was right-hander Kenley Jansen of the Los Angeles Dodgers.
