I watched with the sound off but thought the same thing. Career Samsonov must have played Boll how many times, 100+? And he is a great blocker. But on some of his block attempts vs Boll's fh he underestimated the spin by so much. It almost looked like the ball was flying straight up off his bat. Definitely some extra spin coming from timo. Maybe he got the first sheets of t05 c or n or whatever.They may have been unforced but listening to Timo's racket when he played Vladi and Dima, the silence was deafening and I think the spin was on another level.
