Florida's Kevkhishvili takes NCAA shot put title

FAYETTEVILLE, Ark. (AP) - Mariam Kevkhishvili has won the first title at the NCAA track and field championships.

The Florida junior took the shot put Thursday with a toss of 58 feet, 4 1/2 inches. Sarah Stevens of Arizona State was second.

Kevkhishvili, who is from the nation of Georgia, won indoor national titles in 2008 and 2009.

On Thursday night, Oregon star Galen Rupp was scheduled to run in the 10,000-meter finals. The Ducks are trying for a rare team "Triple Crown" after winning men's titles in cross country and indoor track and field earlier this season.

Rupp qualified for the 5,000 finals in the wee hours Thursday morning after his semifinal heat was delayed because of lightning.

Phil Mickelson, John Daly highlight a day of comebacks in Memphis

MEMPHIS, Tenn. (AP) - Phil Mickelson wasted no time firing up fans with birdies on the opening two holes. Then came a sliced tee shot into the water and a nearly four-putt green. He birdied 2 of the last three holes.

A typical round for 1 of golf's most unpredictable stars.

Returning to work for the first time since disclosing last month that his wife has breast cancer, Mickelson got off to a solid start in the St. Jude Classic with a 2-under 68 that left him two shots behind the early leaders Thursday. He wore a pink ribbon stitched into the side of his white cap and at times looked fatigued.

Jose Maria Olazabal was the day's surprise. Still coping with arthritis pain, the Spaniard shot a 66 and was tied for the lead with Mathias Gronberg and Chris Stroud.

Mickelson, however, was not the only one making a comeback. John Daly played his first PGA Tour event since serving a six-month suspension for off-course activities.

He played in the afternoon and opened with eight pars until a birdie at No. 9 to make the turn at 1-under 34.

Choctaw Nation reach contract with buyer to sell Blue Ribbon Downs; purchaser unclear

OKLAHOMA CITY (AP) - A contract has been reached for the Choctaw Nation of Oklahoma to sell the state's first pari-mutuel horse racing track.

According to a letter sent to the Oklahoma Horse Racing Commission, the American Indian tribe has entered into the contract with Furlong Perfecta LLC, to sell Blue Ribbon Downs in Sallisaw in far eastern Oklahoma.

The sale price is not mentioned in the letter.

A Choctaw spokeswoman says she cannot reveal the identity of the potential buyer. According to incorporation papers filed with the Oklahoma Secretary of State's office, Benita Bowen of Washington County, Arkansas, is the manager of Furlong Perfecta.

Bowen did not immediately return a phone message left Thursday by The Associated Press.

The Choctaw Nation bought the track in 2003 for $4.25 million.

Official: Cowboys knew of earlier canopy collapse

DALLAS (AP) - The Dallas Cowboys knew when they hired the builder of their now-ruined indoor practice facility that a similar structure built by the contractor had collapsed in a storm.

So reports Greg Iannarelli (ya-nuh-REH'-lee). He's chief counsel of the Philadelphia Regional Port Authority, for whom Summit Structures LLC build the first doomed metal-framed fabric structure.

Her says Cowboys official Bruce Mays contacted him not long after a warehouse built by Summit for the port collapsed during a snowstorm in February 2003.

Iannarelli said the Cowboys were considering using Summit and were concerned and wanted to know what happened to the port's structure. Iannarelli says port officials weren't sure what caused the collapse.

The 88,000-square-foot structure Summit built for the Cowboys fell in high winds last month, leaving a scouting assistant paralyzed from the waist down and injuring 11 others less severely.

The Cowboys declined to comment.
