Taiki Mitsumata started working out at catcher during practices at Nagoya Dome on May 23. He caught pitchers during batting practice and tested his arm with throws to second base. He also played one inning as a catcher during a Ni-gun game against Hanshin at Nagoya Stadium on May 26 (he caught Takeshi Kaneko).
Mitsumata has no real experience at catcher, other than a few practices games when he was in junior high school and high school.
