One year removed from his two-fight series with Andy Ruiz Jr. which included the first loss of his pro career in June 2019, Anthony Joshua emerged a safer and more calculated version of himself in Saturday's return. That doesn't mean, however, that the unified heavyweight champion couldn't deliver the boom. Joshua (24-1, 22 KOs) recorded four knockdowns against a determined mandatory challenger in Kubrat Pulev (28-2, 14 KOs) en route to an impressive ninth-round TKO in front of 1,000 fans adhering to COVID-19 protocols inside London's Wembley Arena. Although it was clear Joshua, 31, hadn't forgotten about the upset stoppage he suffered to Ruiz before avenging it by decision in December 2019, the British star was able to balance safety with firepower by relying on his big jab and avoiding getting too reckless in going for the finish. A big part of that was how responsible the 39-year-old Pulev was throughout coupled with how much the native of Bulgaria was able to retain the threat of his right hand in order to hang around deep into the fight.
