The top 16 racers move on to the semis.

"First race of the meet and there’s definitely some jitters but it was a lot of fun," Bacon said. "And I’m kind of just excited to get on my process of warm down and then prepare for tonight."

Bacon finished second in her heat, 11/100ths of a second behind Australia's Kaylee McKeown, a four-time Olympic gold medalist. She said she used racing against McKeown as "a little bit" of a measuring stick to see where she was at headed into tonight's semifinals.

"It’s always good to race a strong competitor, so any chance I get I’ll take it," Bacon said.

McKeown won gold in the 100-meter backstroke earlier in the Olympics, edging Smith, the American world record holder.

She also is scheduled to compete in the 200-meter individual medley.
