Daily Sports has comments from Yusei Kikuchi suggesting that he's decided on beginning his pro career in Japan: "It'll be after I consult with my parents and manager, but I'm thinking domestic. In the future I think I'll go to the Majors if I can, but after building my strength domestically."
There were some hints on Kikuchi's direction in yesterday's news, but it seemed like observers basically took his comments and interpreted what the wanted to hear (Gen comments on this as well). If this most recent revelation is true, I think it's the right choice for Kikuchi. I'll go into once the story is confirmed.
