Briton wins in front of her home Liverpool crowdAmerican Mikaela Mayer hoping for a rematch
Natasha Jonas was pushed to the limit but retained her IBF welterweight crown with a razor-thin split decision victory over the American Mikaela Mayer in a thriller in Liverpool.
Jonas started strongly in the first defence of the world title she won by defeating Kandi Wyatt last July but Mayer steadily grew into the bout and was the busier of the two in several riveting exchanges.
