Uruguay's Pablo Cuevas won the Sao Paulo claycourt tournament Sunday, retaining the title he won last year by beating Spain's Pablo Carreno Busta 7-6 (7-4), 6-3. It was a second straight tournament victory in Brazil for Cuevas, the world No. 27, after he overcame Rafael Nadal on the way to sealing the Rio de Janeiro event last week. The two tournaments take the 30-year-old's career tally to five, all of them won on clay since 2014. ‘No easy fix to help boost Davis Cup' The Davis Cup has not been carrying its weight for the time it occupies in the tennis calendar and there are no easy solutions to rejuvenating the team tournament, according to United States captain Jim Courier. The US plays Australia in a World Group opener in Melbourne this week and although big crowds are expected at the Kooyong Lawn Tennis Club, Courier said the 116-year competition was struggling to resonate to a global audience. "I would say if the Davis Cup was a publicly traded company and the Grand Slams were publicly traded companies, the Davis Cup would have been gobbled up by somebody already," four-time Grand Slam champion Courier told reporters at Kooyong Monday. "It hasn't carried its weight for the amount of weeks that it has in the season. And that hurts me because I'm passionate about it. I wouldn't be here if I didn't care about it. "I think there's obviously passion here for the Davis Cup in this country and it's not an easy discussion as to how to fix it. "But I just hate to see it lose ground, to see players — they're not abandoning it but they're certainly plenty of players who choose not to play and you'd love to see them all put their hands up when it's time." The International Tennis Federation, which runs the Davis Cup, has flagged changes to the tournament which leading players have long criticized for its rigid format and scheduling in the crowded tennis calendar. New ITF president David Haggerty hopes to push a ‘final four' format which would see the semifinals and final grouped together in a one-week event played at a neutral venue. Courier, who won the Davis Cup as a player in 1992 and 1995, said he was "bullish" about the tournament's future under the ITF's new management. — Agencies
