SINGAPORE -- Top-seeded Angelique Kerber struggled to defeat seventh-seeded Dominika Cibulkova 7-6 (5), 2-6, 6-3 on the opening day of the WTA Finals in Singapore on Sunday.Kerber, who secured the top ranking last month, battled Cibulkova for 2 hours, 17 minutes before the Slovakian finally succumbed.It was a really good match from both of us, especially the first set, Kerber said. Its a good start to the tournament like this, where you knew you had to play your best to win.Earlier on Sunday, third-seeded Simona Halep won the first match of the round-robin portion of the tournament by taking a 6-2, 6-4 decision over sixth-seeded American Madison Keys.In Red Group action, Kerber and Halep stand at 1-0, while Keys and Cibulkova are at 0-1.On Tuesday, Kerber will play Halep, while Cibulkova and Keys, both making their WTA Finals debut, will play each other.Kerber posted 29 winners and 32 unforced errors to 36 winners and 34 unforced errors for Cibulkova.Cibulkova dropped serve in the opening game of the match, which initially allowed Kerber to establish a 4-2 lead in the first set.Kerber didnt hold on to the advantage, surrendering her own serve on a second double-fault in the eighth game.That sent the first set to a tiebreaker, where the German eventually prevailed.At the beginning I was too excited, but after a few games I started to play my game, Cibulkova said. It was a really tough one, really close, and in these kind of games its about the small details.Cibulkova dominated the second set, racing to 4-0 lead.In the third, Cibulkova was temporarily in charge with a 2-0 lead, but lost five of the next six games to end up on the losing side of the result.Its been a stellar season for Kerber, who won her first two Grand Slam titles at the Australian and US Opens, and also brought home the Olympic silver medal from Rio.Kerbers never journeyed beyond the round-robin stage of the WTA Finals in three previous appearances in 2012, 2013 and 2015.In the opening match, Keys played erratic tennis throughout the 69-minute contest, losing serve on four of 10 break points faced.I definitely think there were some nerves, Keys said. I think one of her strengths is making you feel like you have to go for more and take the risks. I think sometimes she makes me uncomfortable and I back away from playing my game.Keys held serve in the opening game of the match, but then saw Halep win the next five games for a 5-1 lead in the first set.Halep lost an initial 4-2 lead in the second set, but from 4-4 won the final two games.The Romanian reached the final here in 2014 and now holds a 5-1 head-to-head record against Keys.I think I played exactly what I had to play against her, Halep said. I was focused. Everything went as I wanted, so Im happy. Nike Zoom China Wholesale .

The game started the same way the Vancouver game started the night before, with the Jets taking the first two penalties of the game and killing off the first, but the Oilers getting on the board first, scoring on the second man-advantage. It was only two years ago that Stacy Lewis won the LPGA Tour player of the year and captured the money title. That same year, Lexi Thompson won the Kraft Nabisco at age 19, and Michelle Wie finally broke through with her first major at the U.S. Womens Open at Pinehurst No. 2.This year, only two Americans have won tournaments -- Thompson in Thailand, and Brittany Lang in the U.S. Womens Open. With two tournaments left on the schedule, no Americans will be in the running for the $1 million bonus as part of the Race to the CME Globe.Lang is the only American in the top 10 on the money list, although 65 percent of her earnings ($810,000) came from the Womens Open.The Americans are out-motivated, out-focused and out-driven, and its showing up, said Dottie Pepper, a 17-time winner on the LPGA and now a television analyst. Nobody wants to hear that. But all you have to do is look at the results.What surprises Pepper the most is that the United States won the International Crown this summer, a team event against powerful golfing nations from Asia that are not eligible for the Solheim Cup. England was the only European team in the International Crown.As for the Solheim Cup? The Americans rallied to beat Europe last September.The momentum didnt transfer to individual golf, the same way it didnt coming out of the Solheim Cup, Pepper said.Also concerned is Juli Inkster, who returns as Solheim Cup captain for next years matches in Iowa, although Europe isnt faring much better.Europeans have won only twice this year, Caroline Masson of Germany and Carlota Ciganda of Spain, while only two Europeans -- Anna Nordqvist and Ciganda -- are among the top 20 on the money list.Its always great, especially in the U.S., when we have Americans winning, Inkster said. In the overall concept of the LPGA Tour worldwide, Im not sure it does matter. But for our TV ratings and fan base over these last six tournaments, it killed it.The LPGA Tour is coming off a six-week swing through Asia in which Americans finished in the top five in only two tournaments -- Alison Lee lost in a playoff in South Korea, and Jessica Korda was runner-up in China.---GO TEAM: The PGA Tour is bringing a team event back to the official schedule next year for the first time since 1981 at Disney.The policy board has approved making the Zurich Classic a two-man team competition starting next year, according to two officials. They spoke on condition of anonymity to The Associated Press because an announcement is not expected until next week.Still to be determined is how to assign world ranking points in a team competition, and how to dole out FedEx Cup points. The prize money is likely to be shared.The last official team event was won by Vance Heafner and Mike Holland in the Walt Disney World National Team Championship. Other team events include the World Cup and Franklin Templeton Shootout, though they are not official PGA Tour tournaments.---DJ TO MIDDLE EAST: U.S. Open champion Dustin Johnson is the latest American to head to the Middle East for the Abu Dhabi HSBC Championship.Johnson was confirmed for the European Tour event on Jan. 19-22, which is opposite the CareerBuilder Challenge in the California desert, and means he likely will skip Torrey Pines the following week. Rickie Fowler also returns as defending champion.Over the last seven years, Abu Dhabi has attracted Tiger Woods (twice), Phil Mickelson (twice) Fowler, Jason Dufner and Anthony Kim.Next years field is one of its strongest with Johnson, Fowler, Rory McIlroy, British Open champion Henrik Stenson and Masters champion Danny Willett.---LOW BALL: Rod Pampling became the ninth player tto open a PGA Tour event at 60 or better, but only the fourth player who went on to win.ddddddddddddMike Souchak opened with a 60 in the 1955 Texas Open and sailed to a seven-shot victory.Phil Mickelson shot 60 in the first round at Phoenix and won by four over Brandt Snedeker. The other player to open with 60 and win was Steve Stricker in the 2010 John Deere Classic -- and Stricker wasnt even leading after the first round. Paul Goydos shot 59 that day and was runner-up by two shots to Stricker.Pampling shot 60 in Las Vegas, but he had only a two-shot lead over Brooks Koepka, which turned out to be the margin of victory.No one ever wasted a good start like Pat Perez in the 2006 Bob Hope Classic when he shot 60 in the first round. Perez never broke 70 the rest of the week, posting scores of 73-70-75-78, and he finished 73rd, 21 shots behind Chad Campbell.---ANSER ANNIVERSARY: Ping is celebrating the 50-year anniversary of its Anser putter by making a limited-edition version made from the original molds with components made in the U.S. that vendors supplied in 1966. Chairman and CEO John Solheim is grinding each sole by hand, just as he once did in the family garage. It also has a modern touch of tungsten in the heel and toe.If it sounds like a lot of work, it comes with a steep price. Suggested retail price is $900.The original concept for the Anser putter was drawn on a 78 rpm record sleeve by Ping founder Karsten Solheim in early 1966. The name was inspired by his desire to find an answer to the popular putter at the time. His wife, Louise, suggested he call it Answer but he thought that wouldnt fit on the toe. The w was dropped.---ROAD TO ROYAL BIRKDALE: The R&A is adding qualifying sites at the Singapore Open in January and the Ho Tram Players Championship in Vietnam in April.
