Marty Janzen Autographs
Martin Thomas Janzen (born May 31, 1973) is an American former professional baseball pitcher. Janzen played in Major League Baseball for the Toronto Blue Jays, in the KBO League for the Kia Tigers, and in the Chinese Professional Baseball League for the Macoto Cobras.
Janzen played baseball at Gainesville High School in Gainesville, Florida but did not plan to play baseball after high school and was considering, instead, pursuing a career as a professional bowler. However, after graduating, Janzen spent a summer playing American Legion Baseball with coach Kevin Maris, the son of Roger Maris, and added 10 mph (16 km/h) to his fastball. He signed with the New York Yankees as an amateur free agent on August 8, 1991.
Janzen was assigned to the Gulf Coast League to start his professional career. By 1994, he had reached the South Atlantic League with the Greensboro Bats and was described in the Greensboro News & Record as one of the "Yankees' prized pitching prospects."
