Biryukov won't be sleeping well after that one. Had two match points on Ali's serve at 5-4 in the decider.
The Russian has a colossal left-handed serve - smoked 30 aces during the match. But from watching the match, he seems to be a bit of a headcase which is probably why he's not ranked higher. Seemed to be on the verge on imploding a number of times late in the decider, while Ali stayed very calm and composed and played a super solid tiebreak - including one brilliant bit of relex volleying to go 4-2 up.
