NEW YORK (AP) Umpires are livid that Major League Baseball has sent investigators to their hometowns, asking neighbors a series of questions that include whether the ump belongs to the Ku Klux Klan.

John Hirschbeck and union spokesman Lamell McMorris said Tom Christopher, the Milwaukee-based supervisor of security and investigations in the commissioner's office, had asked questions about Klan membership to neighbors of umpires Greg Gibson and Sam Holbrook, who reside in Kentucky.

In addition, Hirschbeck said similar questions had been asked to neighbors of umpire Ron Kulpa, who lives in suburban St. Louis.

NEW YORK (AP) As the New York Mets went to work on a contract extension for Johan Santana, they also added depth to their bullpen by claiming hometown pitcher Ruddy Lugo off waivers from Oakland.

Lugo was 6-0 with a 5.40 ERA in 38 relief appearances with the Athletics and Tampa Bay last season. Oakland claimed him off waivers in June, then designated him for assignment Friday after claiming outfielder Jeff Fiorentino off waivers from Cincinnati.

Lugo is 8-4 with a 4.39 ERA in 102 major league games. Control has been his biggest problem he has 74 walks and 82 strikeouts in 133 1-3 innings.

ATHLETICS

AUSTIN, Texas (AP) Baylor University assistant track coach Michael Ford said he has agreed to coach defending Olympic 400 meters champion Jeremy Wariner as he prepares for the Beijing Games this summer.

Wariner split with longtime mentor Clyde Hart, who coached Wariner from skinny high school kid to one of the biggest track stars in the world over the past five years, in a contract dispute. Hart said he rejected a new contract for less money.

Ford, 34, said he hasn't yet worked out contract details.

Ford ran the 400 at Baylor under Hart and has been an assistant there for several years. He helped recruit Wariner to Baylor out of high school. His coaching style won't be much different from Hart, Ford said.

COLLEGE FOOTBALL

HEMPSTEAD, N.Y. (AP) A former athletic manager for Hofstra University's football team claims in a federal discrimination lawsuit that players sexually harassed her repeatedly, including when an assistant coach played a sexually explicit movie on a team bus.

Lauren Summa, a 23-year-old graduate student, said that her complaints to coaches and university officials went unheeded, and that she was dropped from the team's athletic staff after speaking out.

A former Miss Teen Pennsylvania from Mount Lebanon, Pa., Summa was hired in 2006 as a team manager, handling duties such as record-keeping and clearing the practice field of equipment. She claims she was subjected to sexual harassment "during every bus trip that she made in the 2006 season."

BOXING

JOHANNESBURG, South Africa (AP) ANC leader Jacob Zuma withdrew from a charity fundraising banquet honoring former boxer Mike Tyson after being criticized by women's groups in South Africa.

In a country with one of the highest rates of rape, Zuma was found not guilty of raping a family friend two years ago. Tyson served a three-year sentence for the 1991 rape of an 18-year-old beauty queen in Indiana.

Reporters arriving at the event were handed a statement from organizers saying Zuma "had been called away on urgent ANC business."

Women's groups had called on Zuma to withdraw from the event. Earlier, the One in Nine Campaign, a group of women's rights organizations, had called "the pairing of Zuma and Tyson particularly distasteful and abhorrent."

JONESBORO, Ark. (AP) Wolves would replace Indians as Arkansas State's mascot under a committee recommendation to the school's chancellor.

The committee, established after the university decided to retire its Indians nickname and mascot to conform to NCAA guidelines, unanimously decided to recommend the Wolves and let chancellor Robert Potts decide whether the name should be the Red Wolves, Black Wolves or just plain Wolves.

The public submitted about 1,500 suggestions to an ASU web site, with more than 700 of them not duplicating another suggestion. From there the list was narrowed to 42 and then to 12.
