Northeast Florida's kings of the pool returned to the top of the podium, and this time, they did it together.
Ryan Murphy wrapped up his Pan-Pacific Championships with two more gold medals and Caeleb Dressel earned a gold and silver on Sunday's concluding events of the four-day meet in Tokyo.
Murphy, from Bolles, and Dressel, from Clay High School, combined for victory on the American men's 4x100-meter medley relay team in the last race of the games.
The quartet of Murphy (backstroke), Andrew Wilson (breaststroke), Dressel (butterfly) and Nathan Adrian (freestyle) swam 3:30.20, with Adrian's final leg making the difference to edge out Japan by five-hundredths of a second.
Earlier in the morning, Murphy dominated the 200-meter backstroke, demolishing the meet record to win in 1:53.57. He finished more than one and a half seconds ahead of Japan's Ryosuke Irie and American teammate Austin Katz.
He completed his Pan-Pacific backstroke sweep after achieving the same feat at last month's USA Swimming national finals in California.
Minutes later, Dressel got his turn in the 50 freestyle, swimming 21.93 but touching the wall second behind American teenager Michael Andrew.
Murphy finished the meet with three gold medals, while Dressel ended up with two golds, two silvers and a bronze. He would have earned another gold if not for an administrative error Saturday, when his first-place 4x100 free relay team was disqualified after USA Swimming officials listed swimmers in the wrong order.
The two qualified for three individual events each for the 2019 FINA World Championships in Gwangju, South Korea.
