BARCELONA, Spain (AP) — Missy Franklin has given herself another chance to tie the record for the most gold medals at a world championships.
The 18-year-old American led the 200 backstroke heats Friday as she attempts to match Tracy Caulkins and Libby Trickett as the only women to win five events.
Franklin could match the record in the 100 freestyle final later Friday, although she's not the favorite in that event.
Michael Phelps holds the men's record with seven golds at the 2007 worlds in Melbourne, Australia.
Also on Day 6 of eight in the pool, Evgeny Korotyshkin and Chad le Clos were the top qualifiers in the 100 butterfly — the event that Phelps dominated at the past three Olympics and the last three worlds.
Ryan Lochte advanced to the semifinals 13th.
