MLB.com: “Tribe lands Japan’s Kobayashi”
The Kobayashi the MLB.com article refers to is relief pitcher Masahide Kobayashi, who signed a two year contract with the Cleveland Indians.
Masahide will not be the first Kobayashi to throw a pitch at Jacobs Field. Takeru Kobayashi threw the first pitch at an Indians game in 2005.
