American Michael Johnson demonstrated why he is considered this year's best 200-meter runner, distancing the field at the Hungalu Grand Prix in Budapest.

The severe heat and a slight wind to his back hindered Johnson, whose time of 20.30 seconds was well off his previous bests of 19.85 and 19.90 earlier this year.

"I was just running for the win," Johnson said. "There was a headwind, so I'm very satisfied with the win since I don't have an Olympic or world championship title yet."

American Olympian Thomas Jefferson was second (20.80).

In the 400, Andrew Valmon of the United States won in 44.61; Samuel Matete of Zambia was second. Butch Reynolds, the world record-holder, ran seventh in 46.89, more than three seconds over his world mark. It was his first 400 in almost a year because of a tendon injury.

In the men's 100, Nigeria's Chidi Imoh upset former world record-holder Calvin Smith of the United States. Imoh ran 10.40 into a strong wind, with Smith (10.45) second.

Merlene Ottey of Jamaica highlighted the women's events with a 22.16 victory in the 200; Nigeria's Fatima Yusuf posted a 400 win in 50.59. . . .
