Daisuke Yamai earned his domestic FA option with eight years of service time on the active roster.
"It took thirteen years, I'm not really sure if that's a long time. My desire to play baseball one year longer, even one day longer, ended up bringing me here," said Yamai. When asked about what he planned to do with the option, he replied, "I'm not thinking about the future right now. I want to keep my spot in the rotation. It might give me something to think about if I can do that."
