Given the ubiquitous nature of the "tweener" -- it seems not a day goes by that an ATP player doesn't attempt one -- it takes a pretty spectacular one to make us sit up and take notice these days. So kudos to you, Lukas Rosol. I'm sitting up and taking notice.
Rosol, who got the nod to play the Czech Republic's opening Davis Cup rubber after Radek Stepanek withdrew to have neck surgery, hit this fantastic sharp-angled "tweener" for a winner against Switzerland's Stanislas Wawrinka. He had a good amount of time to set up, but to hit that angle was pretty special.
