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.
