Claressa Shields unanimously outpointed Danielle Perkins on Sunday night in the first undisputed heavyweight bout in women’s boxing to remain undefeated. Shields, a two-time Olympic gold medalist with titles in five divisions, was in control of the fight from the start. The 42-year-old Perkins, who led St. John’s basketball team in blocked shots two decades ago, won her first five fights before losing to Shields.
