Switzerland’s Stanislas Wawrinka rallied to defeat defending champion Tomas Berdych 4-6, 6-3, 6-4 in the final of the ABN AMRO World Tennis Tournament in Rotterdam Sunday afternoon. The No. 8-ranked Swiss showed his Grand Slam pedigree in the key moments to topple Berdych for the sixth time in a row and improve to 11-5 against the Czech. Wawrinka defeated Rafael Nadal to win the 2014 Australian Open. “It’s been an amazing week,” Wawrinka said. “It wasn’t easy, but every match I found my way. It was a great final. Tomas was playing really well, but I’m happy to turn that match for me and win the title. It’s my first [ATP World Tour] 500 title and winning indoors is something special for me personally. It’s always amazing to win a trophy. It’s the best feeling.” Wawrinka lost his only other indoor final at Vienna in 2007 to Novak Djokovic. Berdych, ranked No. 7, played lights out in the first set, winning 92 percent of the points on his first serve and hitting 12 winners. The Czech got the key break in the seventh game and held his nerve in the 10th, saving his only break point of the set, to serve it out. Both players held serve with ease until the eighth game of the second set, when Wawrinka’s massive hitting from the baseline caused Berdych to lose focus and crack ever so slightly. Wawrinka got the break for 5-3 and then won five of the next six games to lead 4-1 in the third, before Berdych got a break of his own and held for 3-4. Berdych saved a match point in the ninth game, but Wawrinka would not be denied and held easily to capture his ninth career title. ”I had my chances in the beginning of the second set, and I didn’t take them so I think that cost me the match,” Berdych said. ”I can see some positive things because the last time I played him it went a completely different way. I was in control in the beginning and the small differences decided it.” Wawrinka, while out-aced 9-3, won 77 percent of the points on his first serve compared to 69 percent for Berdych. The Swiss hit 25 winners and committed 23 unforced errors, while saving two of four break points. Berdych had 28 winners, 29 unforced errors and defended three of six break points.
