Sebastian Zbik vs. Julio César Chávez Jr., billed as "La Hora De la Verdad", was a professional boxing match contested on June 4, 2011, for the WBC Middleweight championship.[1] It has been the first time that the son of legendary boxing Champion Julio César Chávez, fought for a world title. The bout was on June 4, 2011, at Staples Center, in Los Angeles, California and was broadcast on HBO.[2]
Lineal and The Ring middleweight champion Sergio Martínez was stripped by the WBC after HBO declined to broadcast a bout between him and "Interim" champion Sebastian Zbik, following his victory over Paul Williams. Zbik would be upgraded to full champion and would agree to face their top ranked contender Julio César Chávez Jr..[3]
Zbik was ahead early against Chávez, who was the quicker fighter and landed more punches. However Chávez kept coming forward, countering with hard body shots that seemed to slow the champion down.
After 12 rounds had been completed, judge Steve Morrow had 114–114, while Raul Caiz Jr scored it 115–113 and John Keane 116–112 both in favour of Chavez giving him a majority decision victory.[4] HBO's unofficial scorer Harold Lederman scored the fight 116-112 for Chávez Jr.
This was the fourth time in boxing's history that a father and son combination would both become World Champions.[5] This was also the second combo for the country of Mexico, the first ones being Guty Espadas and Guty Espadas, Jr.[6]
