Ramona Pagel twice bettered her American women's shot put record on consecutive throws and Mary Decker Slaney won the 2,000-meter run Saturday at the Michelob Invitational Track Meet.

Pagel, a 1984 Olympian, had a throw of 66 feet, one-quarter inch on her second throw to better her previous record of 64-21/2, set in Columbus, Ohio, on May 8.The record-breaking mark lasted only as long as it took Pagel to get back in the ring, however, as her next effort sailed 66-21/2. It was the fourth time this year Pagel has bettered her American record.

Natalya Lisovskaya of the Soviet Union owns the world mark of 74-3, which she set last year.

Slaney, competing in her third meet in two years, took her usual position at the head of the pack and cruised to five-second victory over Mary Knisely in the 2,000. Slaney's time of 5:36.65 was more than four seconds off the American record she set in 1984.

Florence Griffith won the women's 100 meters in 10.89 seconds, a personal best and the fastest time in the world this year. The mark places Griffith second on the all-time U.S. performer list, behind Evelyn Ashford's 10.76 set in 1984, and ranks Griffith eighth on the world all-time performer list.

Pam Marshall finished second in 11.18 seconds, followed by Jamaica's Juliet Cuthbert in 11.23 and Jeanette Bolden in 11.28.

Steve Scott, the American record holder in the mile, ran a strong final lap in the meet's featured mile run to finish in 3:56.06. Joe Falcon of the University of Arkansas finished second in 3:56.55, followed by Jeff Atkinson in 3:56.66 and Chuck Aragon in 3:57.01.

In the men's 110-meter hurdles, Roger Kingdom led the entire way to beat Greg Foster and five others in a time of 13.17 seconds. The race was run into a strong headwind of nearly three meters per second.

Kingdom, whose time was the second fastest in the world this year, pulled away during the final 40 meters from Foster, who finished in 13.85 seconds. Kingdom is unbeaten in his seven hurdle races this year.
