July 1 (Reuters) - Seven-time Olympic gold medalist Caeleb Dressel failed to qualify for this month's World Aquatics Championships in Japan after more disappointing results at the U.S. National Championships in Indianapolis on Saturday. In his final chance to make the U.S. team, Dressel finished tied for 22nd in the preliminaries of the 50-metre freestyle, 1.07 seconds behind the leader. Dressel's struggles were not wholly unexpected as the 26-year-old has not competed in a major meet since abruptly pulling out of the world championships in Budapest last summer citing an unspecified health issue. "He's very happy where he's at now," University of Florida head coach Anthony Nesty was quoted as saying by SwimSwam on Saturday. Nesty said Dressel is capable of getting off to excellent starts but struggles to close races.
