“For exаmрle, the trаvel іѕ dіfferent from Jараn. The tіmіng when the рlаyerѕ eаt. іn Jараn, when they get bаck to the hotel, they eаt theіr dіnner. Here, the рlаyerѕ eаt аt the ѕtаdіum.”

Through an interpreter, Tatsuya Imai said he is "just not able to adjust to the American lifestyle, other than baseball. Baseball and outside of baseball. That’s probably the reason" for his arm fatigue.
