Felix Sturm defends his WBA middleweight title this afternoon in Germany against press rival Sebastian Zbik, in a fight that is intriguing mostly because it's going to be a chance to see if Sturm, at 33, has really slipped, or if perhaps last year both Matthew Macklin and Martin Murray were underestimated as opponents for him.

Boytsov, 26, sure loves beating up some old men and never-weres, and he'll continue that scheduling streak today against whiffed ex-prospect Guinn, a 36-year-old American whose nickname ("The Southern Disaster") wound up being quite right in the wrong way.

Guinn has lost two straight to Kubrat Pulev and Amir Mansour, both shutout-type decisions over eight and ten rounds, and just has never managed to put it together. Once he lost for the first time in 2004, a split decision to Monte Barrett, it pretty much just all crumbled for him. He never did beat anyone very good, with his best win coming over Michael Grant in June 2003. That was the fight that sealed Grant as an official disappointment or bust -- not long after, Guinn would be deemed a bust himself.

Boytsov should win without much trouble. Guinn fights for paychecks now. The American can punch, so there's always that, but an upset here would be a true upset. Boytsov is considered one of the better young heavyweights out there, even though he's mostly fiddled around thus far. It's worth noting that despite the eight losses and the general disappointment of his career, Guinn has never lost by stoppage.
