Olympic champions Caeleb Dressel and Ryan Murphy headline the world short course swimming championships, airing on NBC Sports and Olympic Channel: Home of Team USA and streaming on NBCSports.com from Hangzhou, China, this week.
Short course worlds are held in even-numbered years in a 25-meter pool rather than the 50-meter pool used at the Olympics.
Dressel, a short-course king from his days at the University of Florida, looks to build on his seven-gold-medal performance at the 2017 World Championships in an Olympic-sized pool. He entered in his trademark events — the 50m and 100m butterflies and freestyles.
