Ryan Lochte continued to collect gold medals in Shanghai with two World Championship performances on Thursday in both the 200-meter backstroke and as a member of the 4x200-meter freestyle relay, bringing his victory total to four. With two days of competition remaining and at least one event left to swim, Lochte has five medals in all, with wins in the 200 free and 200 individual medley earlier this week and a bronze in the 4x100 free relay. The 14th FINA World Championships continue Saturday.
