Undefeated welterweight world champion Errol Spence Jr. retained his IBF title with an impressive stoppage of former two-division champion Lamont Peterson in the main event of SHOWTIME CHAMPIONSHIP BOXING Saturday night from Barclays Center, the home of BROOKLYN BOXING®.
 
In his first defense since dethroning Kell Brook on SHOWTIME last May, Spence (23-0, 20 KOs) out boxed a tough Peterson(35-4-1, 17 KOs) from start to finish, showcasing a wide array of skills, speed and power. The fight was stopped prior to the start of the eighth round after Peterson's trainer, Barry Hunter, called for the stoppage.
