Kenta Maeda and Hayato Sakamoto recorded a show together for FujiTV's Sport! on Friday. While the show won't be broadcast until 1/18/2010, Sanspo has posted a report with a few observations from the recording. One of them is about a section in which Sakamoto asks Maeda if he wants to play in the Majors. To which Maeda says he has no interest. Sakamoto followed and said he didn't want to go either and finished by saying that he loved Japan.
Maeda also apparently mentioned how nice it would be to play on the same team, but didn't really specify if he meant temporarily, like at the WBC, or permanently, as in with the Giants or Carp.
One thing to keep in mind is that the two players are still young at only 22. All of this could also just be posturing. But it still might be good to file this away for future reference.
