Before making the opening toss, Fonfara, known as "Chicago's Polish Prince," called out the big first baseman — even though Fonfara will actually square off against former champ, Gabriel Campillo, at U.S. Cellular on August 16.
"If he wants to try sparring, why not?" Fonfara said. "We'll see what happens."
Dunn — who is 6-foot-6 and weighs in at 285 pounds — would have to drop a few pounds before facing the 6-foot-2, 175-pound Fonfara.
Dunn hasn't responded to Fonfara's challenge but, if he does, the Big Donkey might want to bring a bat.
