Seeing Serena Williams play three matches over two days in Fed Cup was a rare treat over the weekend. If Fed Cup were to move away from its annual format, however, Williams might compete more consistently. ''Ideally it would be great if it was every two years, just because I want to support it all the time and I don't get to support it as much as I can because we play and train 40-45 weeks out of the year,'' Williams said during a playoff loss to Italy. You feel so bad when you can't.'' Switching to a biannual format is one of the options that the International Tennis Federation is considering for Fed Cup and Davis Cup, which also attracts top players like Roger Federer, Rafael Nadal and Novak Djokovic only sporadically.
ZIELONA GORA, Poland (AP) -- Five-time Grand Slam champion Martina Hingis lost both her singles matches but finished on the winning team as Switzerland beat Poland 3-2 Sunday in a Fed Cup World Group playoff.
Even when Novak Djokovic doesn't play very well, he manages to win titles. Despite hitting 38 unforced errors in a back-and forth match, the top-ranked Serb won the first big clay-court tournament of the season with a 7-5, 4-6, 6-3 win over Tomas Berdych in the final of the Monte Carlo Masters. It was Djokovic's second triumph in three years in the principality, where he lives with his wife and kid, and his 11th straight win in a final. It's been a remarkable start of the season for me.'' Djokovic, who has lost only two matches in 2015, became the first player in tennis history to win the first three Masters tournament of the year after completing the Indian Wells-Miami sweep this spring.
Russia reached the Fed Cup final Sunday, sealing victory at home over Germany in the last doubles rubber. Elena Vesnina and Anastasia Pavlyuchenkova won 6-2, 6-3 against Andrea Petkovic and Sabine Lisicki to stop a German comeback that had seen them recover from 2-0 down in the best-of-five tie after Saturday's play. ''Being a team is very important to us ... and the home support also helped.'' As the Russians celebrated with a lap of honor waving the flag, Germany's Petkovic wept and was comforted by her teammates. Russia's win sets up a match with defending champion the Czech Republic, which beat France 3-1.

Serena Williams thought she was ready for the clay-court season. ''Today has been a big eye opener,'' Williams said after coming back from a set down to post a windy, error-filled 4-6, 7-6 (3), 6-3 win over Sara Errani on Sunday in a Fed Cup playoff against Italy. Brindisi-born Flavia Pennetta then routed 65th-ranked Christina McHale 6-1, 6-1 and Pennetta and Errani beat Williams and Alison Riske 6-0, 6-3 in the decisive doubles match to give Italy a 3-2 win. So I have to play and be ready to hit a thousand shots if necessary.'' Williams also won her opening singles match Saturday but the U.S. sorely missed her sister Venus Williams, who withdrew from the U.S. team due to a personal matter.


Defending champion Czech Republic reached its fourth Fed Cup final in five years by defeating France after Petra Kvitova won the first reverse singles on Sunday. In a match of two big-hitting players, the fourth-ranked Kvitova beat 29th-ranked Caroline Garcia 6-4, 6-4 for an insurmountable 3-0 lead in the semifinals.
