On 26 September, Klitschko earned a one-sided TKO victory over Chris Arreola at the Staples Center in Los Angeles when Arreola's trainer, Henry Ramirez, asked the referee to stop the fight. Arreola was considered at the time one of the division's hardest punchers; however, Klitschko kept Arreola at bay with his left jab and hit him almost at will with his right. Arreola had been influenced by Samuel Peter's defeat to Klitschko in 2008, in which Peter had tried to box from the outside. He therefore employed a game-plan which involved applying constant pressure to Klitschko in order to force him into a high tempo fight. Despite his best efforts, the bout became one sided very quickly. Klitschko consistently proved himself faster, sharper and much fitter than Arreola.
