Claressa Shields chose to fight in her hometown, a once-powerful city that has taken a series of hits, over opportunities to be the headliner on a boxing card in New York, Las Vegas or Detroit. The two-time Olympic gold medalist and three-division champion is facing top-ranked contender Danielle Perkins for the undisputed heavyweight title on Sunday night in Flint, Michigan. “This fight could have been anywhere in the world from the Barclays Center to T-Mobile and to the LCA,” Shields said Thursday in an interview with The Associated Press.
