GENEVA (AP) -- Stanislas Wawrinka brought Switzerland level at 2-2 with Kazakhstan in the Davis Cup quarterfinals on Sunday, rallying to beat Mikhail Kukushkin in four sets.
Wawrinka, the Australian Open champion, never dropped serve in winning 6-7 (4), 6-4, 6-4, 6-4 to earn his first point in the series.
Roger Federer was playing the decisive singles match against Andrey Golubev, who is unbeaten this weekend.
Switzerland is aiming for its first Davis Cup semifinal place in 11 years, cheered on by a raucous 16,000 crowd at the Palexpo indoor arena.
The winner will play Britain or Italy in September.
