Top seed Michael Berrer edged Albano Olivetti 6-4, 3-6, 7-6 (4) in the quarterfinals of the Kazan Kremlin Cup in Russia on Friday afternoon. Berrer, a 33-year-old German veteran ranked No. 132, squeaked out the win at the Challenger Tour event by taking the third-set tiebreaker 7-4. There were just two breaks of serve, one each, as Olivetti, in one of those quirks of big-serving duels, actually won three more points in the match, 102 to 99. Berrer saved six of seven break points, while Olivetti defended four of five. Olivetti, who has the second fastest recorded serve at 160 mph, blasted 15 aces to nine for his German opponent. The 6-foot-8 Frenchman, seeded No. 8, had 55 aces in his three tournament matches. Berrer takes on No. 6 seed Farrukh Dustov of Uzbekistan in one of tomorrow’s semifinals. The 6-foot-4 German, a former world No, 42, will be looking to gain his 14th career Challenger final. He has won 10 titles on the Challenger circuit, but none on the ATP Tour. With his fourth quarterfinal appearance of the year, three Challengers and one Tour level (Montpellier), Olivetti will improve on his career-high No. 179 ranking when the ATP computer updates on Monday.
