Four weeks later, Tampa’s Morgan, 19-2 (17 KOs), lived up to her “Sledgehammer” ring moniker with a fourth-round knockout of journeywoman Simone Aparecida da Silva on January 30 in Memphis, Tennessee. The bout was a time-marking affair for Morgan, who is already the mandatory challenger to Han’s title. It was scheduled for eight, three-minute rounds – mirroring the 10, 3-minute round pace of Han’s abovementioned victory over Holm.
