All it took was a phone call from Notah Begay III to convince Annika Sorenstam and Lorena Ochoa to take a few swings for charity. The two former LPGA stars, who have combined for 99 career wins, will take part in the third annual Notah Begay Challenge, a fundraiser aimed at helping fight obesity and diabetes among Native American youth. "They're very big advocates in their own right for their own causes. For them to get behind this says a lot about what we're trying to do," said Begay, the only full-blooded Native American on the PGA Tour. "It means something to people. The only requirement that Annika had was that she had to make sure her ball wasn't going to count the whole time. She's a little worried. You never lose that competitive desire. She wanted to make sure she had a safety net." Also playing in the mixed-team skins match on Aug. 31 are LPGA players Suzann Pettersen, Cristie Kerr, Morgan Pressel and Anna Rawson and PGA Tour regulars Anthony Kim, Camilo Villegas, Hunter Mahan, Vijay Singh and Rickie Fowler, who is part Navajo. http://sports.espn.go.com/golf/news/story?id=5267962
