Nathan Green shoots 62 to lead Texas Open

The 62 was the lowest round of his PGA Tour career. He tied for second in the 2006 Buick Invitational for his best PGA Tour finish.

Defending champion Justin Leonard, the former University of Texas star seeking a record fourth victory in the event, shot a 70.

Phil Blackmar, Bruce Fleisher and Des Smyth shot five-under 65s at Timonium, Md., to share the first-round lead in the Senior Players Championship, the fifth and final Champions Tour major of the year.

Blackmar holed out from the fairway for eagle to help offset four bogeys, Fleisher made four straight birdies early in his round, and Smyth had a bogey-free day to top the leaderboard. All three are winless this year.

Michele Redman and Maria Hjorth shot six-under 66s to share the first-round lead in the LPGA Tour's Longs Drugs Challenge at Danville, Calif. In-Kyung Kim and Mikaela Parmlid were tied for second at 67. Top-ranked Lorena Ochoa opened with a 70.

ATP takes steps to ban professional gamblers

The ATP men's tennis tour may ban 15 professional gamblers from attending tournaments after finding they were placing bets on-site to exploit a 20-second delay in scores being received by bookmakers, a tournament director said.

The ATP sent organizers of the Madrid Masters tournament, which starts in two days, a list of the names and credit-card numbers of 15 bettors who they want excluded from entry, tournament director Gerard Tsobanian said.

"It's a very international list," Tsobanian said. Some of the gamblers have tried to get into past tournaments by posing as journalists, he added.

Roger Federer will play at the Madrid Masters, ending a three-week layoff and setting up a possible meeting with top-ranked Rafael Nadal.

Edwards, Harvick have heated argument

Witnesses said NASCAR drivers Carl Edwards and Kevin Harvick werein a heated argument Thursday in the Nationwide Series garage at Lowe's Motor Speedway in Concord, N.C.

Witnesses said a member of Harvick's crew had Edwards in a headlock as numerous people tried to separate the two.

Harvick was unavailable for comment.

Edwards didn't deny the two argued but wouldn't discuss the incident.

Edwards triggered a late crash Sunday at Talladega Superspeedway when he tried to push teammate Greg Biffle. But his bumper hooked the corner of Biffle's, sending Biffle into a slide directly into Matt Kenseth. Harvick was caught in the melee.
