Before joining the Cubs, Lim spent 17 seasons pitching professionally in Korea (1996-2007) and Japan (2008-12). He also has pitched for Korea in a number of international events, helping his country to a bronze medal at the 2000 Summer Olympics in Sydney and second place in the 2009 World Baseball Classic.
Will it be awkward if Aoki has to face Lim in a game?
"No. I'm a professional, he's a professional," Aoki said. "He wants to get me out, and I want to get a hit off him."
He smiled and added: "He's a nice guy."
That's always good to know.
