Abraham knocked Taylor out in the final round
Germany's Arthur Abraham opened the Super Six World Boxing Classic with a stunning victory over American Jermain Taylor in Berlin on Saturday.
Taylor, 31, made the brighter start but was soon outclassed by his German opponent and was knocked out in the final round of the fight.
Abraham, who is now unbeaten in 31 bouts, rocked Taylor in the ninth with a fierce right but failed to finish it.
But a thundering straight right sent Taylor to the canvas in the last round.
Abraham, 29, also earns three points for his victory over Taylor in the Super Six World Boxing Classic opener having won by knockout.
Super-middleweight Taylor, who has now suffered four defeats in a 33 fight career, looked comfortable in the opening stages of the fight and made a lively start.
A low blow hurt Abraham in the second, earning Taylor a caution and the American later rocked his opponent with a neat right hand uppercut and left hook.
But Abraham started to find joy with shots to the body of Taylor while also picking the American off with his jab.
A straight right hurt Taylor in the fifth and another low blow from the American in the sixth saw him deducted a point.
The seventh saw Abraham, the former IBF middleweight champion, use two and three punch combinations for the first time in the fight and a left hook rocked Taylor late in the round.
Body shots from the German again did the job in the eighth and a right hook wobbled Taylor in the ninth.
He held on and came through the 10th and 11th relatively unscathed before a left hook in the 12th set up the straight right which finished the job for Abraham.
"I need a couple of rounds to analyse my opponent," said Abraham following his dramatic victory.
"Then I let him (Taylor) punch himself tired before striking back late on."
"I'm really disappointed and pretty sad, it was a hard punch, no questions," said Taylor, who had to be revived and taken to hospital after the bout as a precaution.
"I'm not finished yet, I can win my next two fights."
WBC super-middleweight champion Carl Froch also got his Super Six campaign off to a winning start, with a split decision points victory over Andre Dirrell in Nottingham.
