Arthur Abraham retained his WBO super middleweight world title, when he scored a six round stoppage against Robert Stieglitz in their forth meeting.  Stieglitz  suffered a flash knockdown earlier in the fight.

It was the third win for WBO title holder Abraham from the high-profile quartet of meetings and proves ultimately that Abraham is the better operator of the two.

The first fought in August 2012, with Abraham winning the WBO title with a twelve round unanimous decision. Stieglitz got revenge in March 2013 by stopping Abraham in four rounds due to an eye injury.

They met for a third time a year later, with Abraham scoring a twelve round knockdown to clinch a twelve round split decision and reclaim his WBO crown.
