U.S. Takes Control

Allen Johnson confirmed his status as one of the world’s best hurdlers. Distance runner Regina Jacobs confirmed that she has beaten an iron deficiency problem.

The two led a U.S. resurgence at the World Indoor Championships. Americans won four gold medals after going winless the first two days.

The relatively inexperienced Johnson, 24, performed like a veteran, winning the 60-meter hurdles at 7.39 seconds, a championship record.

The veteran Jacobs, 31, running with the sprightliness of a youngster, became the first American - male or female - to win a distance race at the championships. She took the women’s 1,500 meters at 4:12.61.

The U.S. dominated the final day of competition, and wound up leading the medals table with a total of 15.
