MEMPHIS, Tenn. (AP) — Kei Nishikori of Japan came to Tennessee wanting more matches to help him keep up his strong start to 2014. He's leaving with his fourth career title after successfully defending a championship.
Nishikori repeated as champion at the U.S. National Indoor Tennis Championships, beating Ivo Karlovic of Croatia 6-4, 7-6 (0) on Sunday. He made this his first successful title defense, taking the $103,100 winner's check and 250 points on the ATP Tour at The Racquet Club.
"It's amazing actually first time to defend title and especially here," Nishikori said.
"I had a great memory last year playing great, and today was perfect. I think I started well. There was a couple matches before I was kind of slow start. Today was different, and it wasn't easy because he had a lot of aces ... not many chances to break. I have to stay calm and stay focused to whole end of last tiebreak. Yeah, I was really happy to defend."
Nishikori, who came in ranked 16th in the world, was given a wild-card entry into this tournament, which was a 500-point event a year ago when he won here. He rewarded the decision by improving to 11-2 this year and becoming the first back-to-back winner since Tommy Haas won in 2006 and 2007.
"Win this title, that's nothing better than this," Nishikori said. "I'm really happy."
Karlovic came in having not been broken even once this week and looking for his sixth career title. The big-serving Karlovic and his 20 aces couldn't counter Nishikori's precision over 90 minutes. Nishikori saved both break points he faced while winning 86 percent on his first serve (38 of 44).
"He returned really well," Karlovic said. "I was not hitting as wide as I usually can, but he was really fast. He was returning well, and then he won. He was a little bit better."
American Eric Butorac and Raven Klaasen of South Africa beat Bob and Mike Bryan 6-4, 6-4 for the doubles title. It's the second time this year Butorac and Klaasen have beaten the Bryans after knocking them out of the Australian Open in January.
