Coleman breaks 60m world indoor record

Christian Coleman broke the world indoor record in the 60 meters in 6.34 seconds Sunday to win his first U.S. title in the final event of the USA Track & Field Indoor National Championships in Albuquerque, New Mexico.

Coleman had run a worldbest a month ago at the Clemson Invitational, but the mark was not recognized because electronic blocks were not used.

This time there was no doubt when he put on an extra burst about midway through the run, pulling away from former champion Ronnie Baker, who finished with a personal best of 6.40.

Sharika Nelvis set the crowd buzzing with an American record in the 60 hurdles at 7.70.

She had to come from behind to win it, surging over the final hurdle to kick it to the finish.
