Former first baseman Bill Buckner will fill in for WGN's Cubs analyst Bob Brenly during the May 20 interleague game in Boston, where he is both loved and hated for letting a ground ball go through his legs during Game 6 of the 1986 World Series.
Buckner, of course, was an all-star first baseman for the Cubs before playing in Boston.
Brenly will be absent while watching son Michael, who is a catcher for the Cubs' Class A Daytona team
