TOKYO: Swimmer Ahmed Hafnaoui of Tunisia was the surprise winner in the men’s 400-meter freestyle at the Tokyo Games. Australia’s Jack McLoughlin settled for silver after leading much of the race, and Kieran Smith grabbed another Olympic medal for the Americans. It is the third swimming medal for the US after Chase Kalisz won the first American medal of the Tokyo Games, taking gold Sunday in the men’s 400-meter individual medley. Jay Litherland made it a 1-2 finish for the powerhouse US team, rallying on the freestyle leg to take the silver. Brendon Smith of Australia claimed the bronze. Kalisz, a protege and former training partner of Olympic great Michael Phelps, touched first in 4 minutes, 9.42 seconds. Litherland was next in 4:10.28, just ahead of Smith (4:10.38). Meanwhile, Americans April Ross and Alix Klineman have cruised to a straight-set victory over China in their Olympic beach volleyball opener. Ross is making her third appearance in the Summer Games with her third different partner. She’s already won a silver medal and a bronze. Klineman is making her Olympic debut. They’re among the favorites for the gold medal in Tokyo. The Americans won the first set 21-17 and then took the second 21-19 over Xue Chen and Wang Xinxin. Ross and Klineman play Spain on Tuesday. The American men’s team of Jake Gibb and Tri Bourne play their first match on Sunday night. Bourne was a late substitute after Gibb’s original partner, Taylor Crabb, tested positive for COVID-19 when he arrived in Japan. They’ll face Italy.
