LOUISVILLE, KY., JAN. 30 -- Former world record-holder Kenneth Lowery of Chicago State University won the 500-meter dash in 1 minute 2.24 seconds tonight at the Mason-Dixon Games at Broadbent Arena.

"The time was okay," said Lowery, whose best in the 500 was his one-time world record of 1:00.17. The record is now 59.90, set by American Roddie Haley last March.

Former Southeastern Conference pole vault champion Greg Duplantis beat a field loaded with one-time 18-foot vaulters, but he needed to go just 18 feet 1/2 inch to do it. Afterward, he was realistic about his Olympic chances.

Duplantis and the other vaulters were aiming at 18-3 1/4, the height required to qualify for the Olympic trials, but they'll all have to wait.

Earlier, Kim Turner-McKenzie, the 1984 Olympic 100-meter hurdles bronze medalist, won the women's 55-meter hurdles in 7.66 seconds, beating Pat Davis by a stride.

Rhonsa Brady, who made the Olympic team as a hurdler at age 15 and is attempting a comeback at 28, won the 55-meter dash in 7.06. She won the race just a half-hour after crashing early in the 55-meter hurdles.
