‘That’s a guppy’: Baumgardner swats aside Britain’s Dubois as feud escalates

• American dismisses Dubois as not on my level'

• Baumgardner targets bouts with Taylor or Serrano

• British stablemate touts fight as best versus best'

A dismissive Alycia Baumgardner said Britain's Caroline Dubois still has more to prove before the American will entertain a fight between the two unified champions.

That was the curt assessment from Baumgardner early Saturday morning after she retained her WBA, WBO and IBF junior lightweight world titles with a controlled, at times punishing display across 10 three-minute rounds against Bo Mi Re Shin in a main event that started well past midnight at Madison Square Garden.
