Kenley Jansen’s Career
Minor League Beginnings and Conversion to Pitcher
In 2004, the Los Angeles Dodgers signed Jansen as an undrafted free agent catcher. He began his professional career in the Dodgers’ minor league system, playing for teams like the Gulf Coast Dodgers and the Ogden Raptors. While his defensive skills as a catcher were evident, his hitting did not progress as the organization had hoped. A pivotal moment in his career came during the 2009 World Baseball Classic, where he played for the Netherlands national team. His strong throwing arm caught the attention of the Dodgers’ management, who suggested he transition to pitching. This decision proved to be a turning point, and Jansen quickly rose through the minor league ranks as a relief pitcher.
