Yeah, it's a good win. Rainer's experience and skills make him a very tough opponent so I'm glad Kei came through after losing the second set. Really wanted to see this match!
Kei and Radek are practice buddies in Florida, so they should know each other's game very well. But this will be their first encounter in a match... Wish Kei didn't have to play two matches today but it should be an exciting match if both of them play well.
