According to Nikkan Sports, Chen will likely stay in Japan for one more season and will ask the team to be posted after the 2011 season.
Said Chen, "I had a lot of games where I gave up a lot of runs this season so I'm not satisfied with my year. There are still plenty of things I need to learn in Japan."
According to Sponichi, Wei-Ying Chen's agent is expected to visit Japan some time in mid-November to discuss contract details. It seems Chen may also be considering the Majors, although I'm not exactly what his current situation is.
