MINNEAPOLIS (WCCO) — Lakeville teen Regan Smith claimed another gold medal and two more world records Sunday at the world swimming championships in South Korea.

Smith joined her teammates Lilly King, Kelsi Dahlia and Simone Manuel in victory in the 4×100 medley relay with an overall world-record time of 3:50:40 — besting Australia’s relay team by just over 3 seconds.
