In a very rare occurrence, a fighter landed zero punches in a single round. Bermane Stiverne only threw four punches and none of them landed in his rematch with WBC heavyweight champion Deontay Wilder at the Barclays Ceneter in Brooklyn, New York. In their first fight, Stiverne was the only man to take Wilder the full distance in January 2015.

Wilder on the other hand, threw 39 punches and landed at 38% - including 60% of his power shots.

Undefeated heavyweight world champion Deontay Wilder retained his WBC title in his sixth defense with a dominant first-round knockout of mandatory challenger Bermane Stiverne in the main event of SHOWTIME CHAMPIONSHIP BOXING Saturday night on SHOWTIME from Barclays Center, the home of BROOKLYN BOXING®.

Wilder (39-0, 38 KO's) knocked Stiverne (25-3-1, 21 KOs) to the ground three times before referee Arthur Mercante halted the bout at 2:59 of the opening round. After Stiverne took Wilder the distance in their January 2015 title bout, Wilder has now knocked out every single opponent that he has faced in his career. Watch Wilder knocking out Stiverne HERE.

Wilder first knocked Stiverne to the ground with a devastating one-two combination that caught the Haitian challenger on the nose. Seconds after Stiverne got back to his feet, Wilder landed another clean combination with a big left and an overhand right that sent a stunned Stiverne back to the canvas. The final blow came in the waning moments of the opening round as Wilder landed four clean punches to the face of a wobbly Stiverne.

After the brutal knockout, an emotional Wilder was asked by SHOWTIME Sports® reporter Jim Gray about a possible fight with unified heavyweight champion Anthony Joshua.

Former welterweight world champion Shawn Porter (28-2-1, 17 KOs) defeated Adrian Granados (18-6-2, 11 KOs) via unanimous decision (scored 117-111 by all three judges) in an exciting fight between two all-action competitors that served as the co-featured event of SHOWTIME CHAMPIONSHIP BOXING. The victory makes Porter the mandatory title challenger for unified welterweight champion Keith Thurman's WBC belt.
