Phelps claimed five medals at the 2002 Pan Pacific championships, including three gold (200-metre and 400-metre individual medley [IM] and 4 × 100-metre medley relay). At the U.S. spring nationals in 2003, he became the first male swimmer to claim titles in three different strokes at a single national championship.
Phelps’s retirement was short-lived, as he announced his return to competitive swimming in April 2014.
