Mayer broke and served for the opening set, immediately broken back, and started choking in the tiebreak too. However he recovered, taking 5 points in a row from double minibreak down.
Next set, runs away with it, serving for the match, 5-2 up. Broken to love. Kunitsyn holds to love.
Mayer tries again to serve it out, 15-0 from big serve, double fault, bad error, silly error, double fault. From serving for the match, he lost 11/12 points. Goes on to lose tiebreak.
Final set was very nervy, but Mayer just nicked a break midset as Kunitsyn tightened up.
Good win, but ugly, ugly choke
