The 36-year-old Spence (28-2, 22 KO) was brave and tough but just slower than he used to be, couldnt generate the same power he used to, and wasnt able to find consistent results.As the bout wore on, he obviously had issues with his stamina, which just made it all worse. Tszyu (28-3, 18 KO) really didnt bring a ton of pressure or anything, and was able to simply out-point Spence over 12 rounds.Spence vs Tszyu official score cardsJudges scored the bout 117-111, 117-111, and 118-110 for Tszyu. There was no home cooking here; these were fair scores. Myself and Wil Esco unofficially scored the bout 117-111 and 117-111 for Tszyu, as well.While it wasnt immediately scary or a sustained, bad beating or anything at least not by pro boxing standards it was also not the sort of fight where you could imagine suggesting that Spence continue boxing.160 is my new division and I feel strong, Tszyu said after the fight. There were times I had sleepless nights thinking, Man, am I (out of) my depth? What am I going to feel like facing a legend like that? But it was one hell of a show and I understand why hes one of the greats.Tszyu said hes hoping to fight for another world title, now as a middleweight, and said that beating a great one like Errol Spence tops any world title for me.Errol Spence Jr announces retirement after lossIt was a great fight. Congratulations to Tim and (trainer) Jeff Fenech, Spence said. It was a good showing by Tim. I answered a lot of questions about myself, and now its time to go home with my family and start a new life.Asked to clarify if that meant he was retiring, Spence replied, Yeah, for sure. Ive got my faculties intact. My money is good and working for itself, so everythings good, man. Ive got a beautiful family and I thank God that Im able to leave this sport with my faculties intact and my family by my side. Everythings going to go well.
