WASHINGTON -- Tiger Woods is not sure whether his ailing back will allow him to play in the Masters, which is two weeks away. Authentic Wholesale Nike Shoes . "For Augusta, its actually still a little too soon, to be honest with you," Woods said Monday at a news conference to announce that Quicken Loans is the new title sponsor of his golf tournament. "Thats kind of the frustrating thing about this." The Masters is the only major tournament the 38-year-old Woods has never missed. Four of his 14 major championships came at Augusta National, including his first in 1997. He last won the green jacket in 2005. This years Masters is April 10-13. Woods is off to the worst start of his 18 years on tour, and hes been troubled lately by back problems. He stopped playing in the final round at the Honda Classic on March 2 because of what he called back spasms and pain in his lower back. He tried to defend his title the following week at Doral, only for his back to flare up again in the final round, when he shot a 78, the highest Sunday score of his PGA Tour career and his first closing round without a birdie. Then last week, Woods withdrew from the Arnold Palmer Invitational because of persistent back pain. "Ive had a couple weeks off and getting treatment and just working on trying to get ready for Augusta," Woods said Monday. "As of right now, its still too soon, which is, as I said, pretty frustrating." This has been the longest sustained problem Woods has had with his lower back. He first showed signs of back pain at Bethpage Black at The Barclays in 2012, which he attributed to a soft bed at his hotel. He felt twinges during the final round of the PGA Championship last year, and when his back bothered him in the final round of The Barclays two weeks later, he said it was unrelated. At Mondays news conference, Woods discussed a deal through 2017 for his tournament to be called the Quicken Loans National. It will be played June 26-29 at Congressional this year. AT&T was in the final year of its contract as sponsor. The AT&T National began in 2007 with a military theme built around the Fourth of July in the nations capital. It has been held at Congressional for all but two years, in 2010 and 2011, as the course prepared to host the U.S. Open. In those years, it was played at Aronimink outside Philadelphia. Congressional is under contract through 2014, and Woods said there will be a vote next week to determine whether the club would host every other year in 2016, 2018 and 2020.

Mauer struck out to end the inning, with a runner on third base in the seventh on Wednesday and the Twins trailing 1-0. Everybody does this, of course, in a sport with a 30 per cent success rate at the plate long proven to be a benchmark of excellence. Failures this year have piled up for Mauer faster than usual for the six-time All-Star, three-time American League batting champion and one-time AL MVP. "Im a heck of a lot more frustrated than they are," Mauer said that night, when asked about those jeering fans. The sound of those boos has been jarring, considering hes the hometown guy from St. Paul with the handsome looks and the hitting skills to build a .321 career batting average, the best among all active players in baseball with at least 3,000 plate appearances. Minnesotans are fiercely proud of and protective of their natives, so Mauer figured to have a lifetime pass in the popularity department here. After signing that $184 million, eight-year contract extension in 2010, though, he has become a more-frequent target of criticism from fans frustrated by the teams struggles the past several years. The 28 home runs he hit in 138 games in 2009 were a one-year wonder. Lingering lower-body injuries limited him to 82 games in 2011. This season, his on-base-plus-slugging percentage was at a career-low .704 entering the weekend series in New York. Mauer is also on pace to blow by his career-high strikeout total of 89 set last year. "I feel pretty good actually, which is even more frustrating," he said. Cheap Nike Shoes China Free Shipping. . "Im hitting a lot of balls hard and just not having much to show for it. So hopefully that turns here soon." Mauer isnt the only one sputtering with the Twins. The teams batting average with runners in scoring position fell to .214, the second-worst in the league, after losing three of four games to Texas this week. "Were putting together a lot of good at-bats but still not driving people in with runners in scoring position. Thats the main focus, getting guys on, but we cant get them in," second baseman Brian Dozier said. Mauer reluctantly gave up his job as the catcher to better protect himself from another concussion, after missing the final six weeks of last season following a foul tip that hit him in the head. The loss to the Twins of Mauers intelligence and defence behind the plate was supposed to be trumped by an increase in his availability and production at a less-taxing position. He missed five games with back spasms earlier this month, but since then he said he feels fine. The problem has been these paltry totals: nine extra-base hits and 15 RBIs through Thursday. "The expectations are very high for him. People get frustrated. I just dont want Joe to get frustrated. I know he is a little bit right now, because he doesnt have the results he wants. But I dont want to put any more pressure on the guy," manager Ron Gardenhire said. "I just want him to just keep being himself, keep swinging, and hell be fine." ___ Dave Campbell on Twitter: http://www.twitter.com/DaveCampbellAP ' ' '
