Choi Ji-man (Tampa Bay) is nicknamed "Gee."

Los Angeles Dodgers pitcher Ryu Hyun-jin, who has been called "The Host," uses the nickname "Monster" for the second year in a row.

Eric Thames (Milwaukee Brewers), who played in the KBO league, introduced a new nickname, "Mr. T. He played in a uniform nicknamed "SANG NAMJA," which was acquired in Korea last year.

Otani Shohei (LA Angels) has chosen "Showtime" (SHOWTIME), which he came up with in his name.

Meanwhile, uniforms worn by players will be auctioned and all proceeds will be donated to youth baseball development funds.
