Well he really is a top 200 singles player with a career high of 70 that only stopped playing singles because his rank was too low (around 100) compared to his doubles rank. He is not a typical doubles specialist.
See this post here. The one you originally replied too? The one you replied to trying to correct my grammar or something? It is about Lukas Dlouhy, which obvious if you:
a) read the quoted post in that post
b) think for two seconds - Polansky is not a doubles specialist and rarely plays doubles
c) See that I wrote a career high of 70, which is not PP's career high or close to it.
