Don't think he's really a step up from Rudenko. Don't be fooled by Wach being competitive with Whyte, he's been washed up for the last couple of years and would lose to Rudenko now.
Helenius clipping the crude Kownacki with a big shot and scoring a huge upset is FAR more likely. Wach doesn't have a prayer there.
Must watch. Would not be surprised if Szpilka was upset here. Radchenko is more game than his record would suggest.
