Organizers of the Bet-at-Home Cup in Kitzbuhel had planned for the second round --- eight matches -- to be completed Wednesday, but Bolelli's win was one of only three to determine winners. Two other started but were suspended and three never saw the court.
The new schedule calls for nine matches -- the rest of the second round and the quarterfinals -- Thursday, which would get the tournament back on schedule to end Saturday.
Bolelli had three breaks against Mayer and lost his serve just once, which forced the second-set tiebreaker. He ended up winning more than two-thirds of the points on serve.
Fifth-seeded Martin Klizan defeated Pavol Cervenak 6-4, 6-4. Two of his three breaks came in the second set.
Also, Lukas Rosol topped Antonio Veic 6-3, 5-7, 6-3 behind an eight-ace attack. He piled up five breaks in the match.
No. 1-seeded Philipp Kohlschreiber was down 0-3 to Attila Balazs and Wayne Odesnik led Jurgen Zopp 5-7, 7-5, 3-0 in the suspended matches.
