Will Middlebrooks' path has finally led to the big leagues.

The hard-hitting infielder has been called up to take the place of Kevin Youkilis as the third baseman heads to the disabled list to deal with back pain.

Middlebrooks' career path hasn't always been clear cut. He had promise as a high school football player, and he's spent time playing shortstop, too.

Middlebrooks chats with Peter Gammons about his athletic past and what it feels like to finally be playing for the Boston Red Sox.
