 Welcome back to Sports Econ 101. I'm Edward Brown along with Mike McDowd, Russell Jackman, our special guest, Marvin Deloach Jr. Thank you. Question number one. Who is the only baseball player who has appeared in a World Series game at both Wrigley Field and Comiskey Park? Tim Chicago. I'll say Ernie Banks. Ernie Banks never got in. I don't think he never got in the World Series. Poor guy.
