I don't believe that is Prause. It sounds more like the scottish and new commentator from Spain (correct me please I can't remember)? Michael is the other German commentator so I'm not even certain if Prause was commenting at all during the tournament. Just going through the videos on ittv I can't really seem to find his voice.
Could be that it's not Prause, but I seriously doubt this guy could be from Spain. The accent sounds german.
