Missy Franklin and Ryan Lochte lead the U.S. against European all-stars on the first of two days of competition at the seventh Duel in the Pool in Indianapolis, on NBC Sports Live Extra on Friday night.

Franklin, Lochte and the U.S. hope to run their Duel in the Pool record to 7-0. The first three meets (all in odd-numbered years) were wins over Australia. The last three came against European all-stars.

The European roster includes the world’s best female all-around swimmer, Hungary’s Katinka Hosszu, who in August swept the individual medleys at a second straight World Championships.

Start lists for Friday’s events can be found here.
