Mixed-up mayhem proving popular

BUDAPEST - Matt Grevers wasn't sure what was going on. He wasn't alone.

One of swimming's newest - and certainly craziest - events was showcased on Wednesday at the World Aquatics Championships, where the United States set a pair of world records while winning the 4x100m mixed medley relay.

Grevers led things off by swimming the backstroke, giving the Americans a slight lead, but breaststroker Lilly King - competing against seven men, including Britain's world-record holder Adam Peaty - was only in fifth place when she passed off to teammate Caeleb Dressel.
