At this point Wach by KO. I still haven't seen it, but by all accounts Grant was on thin ice every step of the way against Botha until he pulled it out of the fire with the one-punch KO in the last minute of the last round. If old Botha really had him that hurt that often, then Wach by KO is almost a certainty (and I don't even particularly rate Wach all that highly). Of course, Mariusz could be hiding a complete glass jaw that just hasn't revealed itself in any small way until now - but that's a long shot and really Grant's only hope. SLIM puncher's chance, that's it. (with a high likelihood of being knocked out himself). Almost no way it goes 12 rounds, unless Wach gasses early going for the finish ineffectively and they wind up hugging it out for most of the night.
Wach takes it by KO. However I don't want this fight because I'd like to see Grant fight Klitschkos. He won't win but at least we won't duck them (Povetkin), or be a total mismatch (Mormeck)
Wach wins rather easily, but it would be a good fight to bolster his body of work at this point and it is worth a watch. Alternatively, I'd like to see Grant fight Fury, Price or even Gerber. Helenius needs more than Grant can offer at this point.
