Serrano landed a massive left hook late in the first round and had Taylor badly hurt. Taylor was saved by the bell, a benefit of most women's fights being contested with two-minute, rather than three-minute, rounds. After the bell, Taylor's corner implored her to make the fight a boxing match rather than the kind of fight Serrano preferred.
