BEIJING _  Jamaica’s Usain Bolt won the 200 meters on Wednesday, picking up his second gold medal and a new world record in the process.

Bolt’s 19.30 time in the 200 was faster than American Michael Johnson’s 1996 previous world record of 19.32.

After a series of disqualifications and protests, American Shawn Crawford, gold medalist four years ago in Athens, won the silver with a time of 19.96 seconds; countryman Walter Dix took bronze with a 19.98 split.

The Washington Post reported that second-place finisher Churandy Martina (19.82) of Netherlands Antilles was disqualified for stepping out of his lane. So was third-place finisher Wallace Spearmon (19.95) of the United States. That gave Crawford and Dix the silver and bronze medals.

Bolt became only the ninth runner in Olympic history to win both the men's 100 and 200 meters at the same Olympic Games.

Carl Lewis was the last to pull off the double when he won the 100 and 200 en route to four gold medals at the 1984 Olympic Games in Los Angeles.
