The United States fell to Denmark 2-1 at the Hopman Cup after a late arrival of Caroline Wozniacki & Frederik Nielsen defeated Bethanie Mattek-Sands & Mardy Fish, 7-5, 6-3, in the deciding mixed match.

Fish won his singles match after he defeated Nielson 4-6, 7-6, 6-4. Wozniacki, who arrived only four hours prior to match time, defeated Mattek-Sands 7-6, 6-2 to tie the series before the duo went on to take the deciding the match.

Due to Wozniacki's late-arrival, tournament officials allowed the men's singles to be played first to give her time to warm up on the hard courts. Wozniacki went straight from the airport terminal to the arena with little time to get in competition mode.

"It's the first time that I've done that, and I felt a bit nervous. I just started off playing too short and Bethanie just went for shots, made a lot of winners and it was tough for me to get into the points. But I just kept focusing," said Wozniacki.

Fish, on the other hand, broke Nielsen when he was serving for the match up 6-5 in the second which forced a tie-breaker.

"The first one of the year is never pretty. I feel like I haven't had much time off. It feels like only a couple of weeks ago I was in London at the tour finals. I am working on a lot of things on the mental side of things to improve myself," said Fish.

Fish has had a great 2011, moving up in the rankings to top 10 for the first time, currently ranked eighth and says it is partly due to his loss of 30 pounds.
