When the U.S. Open begins in August, Caroline Wozniacki, the top-ranked woman tennis player, won't have to worry about a place to stay.

Ms. Wozniacki paid just under $9 million for a pair of two-bedroom apartments at 15 Union Square West, the new glass-clad luxury condominium in the one-time home of Tiffany & Co.

The apartments have soaring cast-iron arches that date back to construction of the original Tiffany building in 1869. The arches and 16-foot ceilings are encased behind a box-like wall of dark glass.

The Danish Ms. Wozniacki is the daughter of two athletes originally from Poland, and lists her residence as Monte Carlo in Monaco. The New York apartments were purchased as pied-à-terres, brokers said.

The purchases were made through two limited-liability companies, but the sales documents for both were signed by Ms. Wozniacki's mother, Anna, who played on Polish women's national volleyball team.

The closing took place in May, less than two weeks before the start of the French Open, where Ms. Wozniacki was the top seed. But she lost in the third round, and may be at risk of losing her No. 1 ranking in the Women's Tennis Association.
Shlomi Reuveni, a broker at Brown Harris Stevens, who is marketing the building, declined to comment on the transactions.

Sales in the boutique building, which has 36 condos, were launched in the spring of 2008, but stalled during the financial crisis. For a time, the building was taken off the market.But since December, Mr. Reuveni said activity had picked up sharply, and now close to half of the condos in the building have been sold.

The building once had a painted cast-iron facade. But in the 1950s after a piece of the facade fell off and struck a pedestrian, the building was encased in white brick.

One of Ms. Wozniacki's apartments faces Union Square Park and overlooks a colorful farmers market that is open four days a week. The other faces north toward East 15th Street.

Email messages left with Ms. Wozniacki's management team weren't returned.

The building has a number of athlete-friendly amenities, Mr. Reuveni said, including a 50-foot lap pool and spa with saunas, treatment and massage rooms, a gym and a yoga room that doubles as a boxing training room.

Former tennis star Anna Kournikova has put up her Miami Beach, Florida mansion for sale with an asking price of $9.4 million, according to real estate listings.

The ivy-covered home features seven bedrooms, eight bathrooms and is right on the waterfront. The home also has a coral rock pool deck, a two-story guest house and a sauna all within its 6,600 square feet. Photos of the home can be seen here.

The property was built in 2000 and is located on gated Sunset Island with a style described as Mediterranean. The guest house is one bedroom, one bathroom with a kitchen and living room. The home, however, does not have a tennis court.

Kournikova is best known for her tennis career which included two Grand Slam titles for doubles with partner Martina Hingis. Kournikova's professional career has slowed down as a result of injuries and back problems. She recently came in at No. 19 on Maxim's Hot 100 list.

The athlete is also known for her relationship with pop star Enrique Iglesias that began in 2001. During an interview with Graham Norton on BBC in 2010, she confirmed that the two are still dating but have no interest in getting married.

There's one surprise, though. There doesn't seem to be a tennis court. Perhaps Ms Kournikova is more concerned with her new gig hosting the US version of The Biggest Loser.
