On the 25th, Lotte announced that they would change the registered name of infielder Masami Ishigaki (27) to "Katsumi Ishigaki."

Masaru Ishigaki commented through the team, "The name Katsumi expresses my wish that 'Umi (The Marines) will win', as well as my determination to beat the opponent and contribute to win. I will continue to fight with all my might. I appreciate your continued support."

He was transferred from Chunichi in the active player draft last season, but injuries affected his performance, with a batting average of .143, 0 Home Run, and 0 RBI in 20 games. This season, he has changed his registered name and is taking on the challenge.
