Must be pretty serious if he would pull out at this score?
yes he could not run and he could hardly serve, made a kind of serve without jumping at all. Berlocq was disoriented for a while and Kohli even had 3 break points, but then Berlocq regrouped, and there was no way Kohli could win.
funny comments saying "he seemed to be injured" and "some strain in the thigh"
it's a real big injury he had
and the drama is that he was leading 0-30 on Berlocq's serve, Berlocq made a 1000-th dropshot, which Kohli was going to easily put away for 0-40, I could already foresee his win ... and he made an unbelievable error.
Next thing we saw Kohli was on the chair and then couldn't run and serve
Credits to Berlocq for his fight and some very good shots
