On June 10, 2007 39-year-old Masumi Kuwata enters a game for the Pirates. He becomes the oldest major league rookie in 47 years, since Diomedes Olivo debuted – also with the Pittsburgh Pirates. Kuwata allows one hit in two innings, but it is a two-run homer to Alex Rodriguez. Ken Takahashi, another veteran of Nippon Pro Baseball, will debut at age 40 in 2009.
