Usain Bolt, Justin Gatlin advance to 100-meter semifinals at world championships

Usain Bolt

Usain Bolt breezed through his first-round heat in the 100 meters at the World Championships on Saturday, advancing to the semifinals on Sunday. The final is also Sunday.

Bolt won his heat in 10.07 seconds. The only source of trepidation came when the runner in the lane next to Bolt false started. It brought back memories of the 2011 World Championships final, when Bolt false started and was disqualified.

The BBC asked Bolt if his “heart skipped a beat” when he heard the gun go off a second time to signify the false start.

“I saw it; he moved,” Bolt said of Kemar Hyman of the Cayman Islands. “I knew it was him. So, no I didn’t (skip a beat).”

The six-time Olympic champion was then asked if he’s feeling confident he’ll be able to win back the 100-meter world title Sunday (11:05 a.m. ET semifinals, 1:50 p.m. final).

“Always,” he said.

NBC has coverage from 12:30-2 on Sunday.

All of the medal contenders advanced to the 24-man semifinals. Here are the key qualifiers:

1. Mike Rodgers (USA) 9.98
2. Justin Gatlin (USA) 9.99
