RIO DE JANEIRO: Good old Michael Phelps, golden again. For teenagers Katie Ledecky and Simone Biles, their star turns in the Summer Olympics might be just beginning. From the pool to the gymnastics floor, Team USA had nice day at the Rio de Janeiro Games. Not all the American stars were winners Tuesday, though. Serena Williams lost on the tennis court and the US women’s soccer team gave up a late goal and ended up in a draw with Colombia.

But a new generation of US athletes is ready to take up the banner of Olympic standard-bearer from Phelps, a grizzled veteran at 31. Phelps earned his 20th career gold medal after taking the 200-meter butterfly. He erased the bad memories from his loss in the same race in London to South African Chad le Clos. Phelps got off to a rousing start at the Rio Games by leading his 4x100 freestyle team to the gold medal on Sunday. On Tuesday, Phelps’ face bared a familiar scowl as he walked out on to the deck. He held off Japan’s Masato Sakai by four-hundredths of a second, with Hungary’s Tamas Kenderesi taking the bronze.

His 21st gold came later Tuesday night after swimming the anchor leg on the 4x200- meter relay. Ledecky strode atop the medal podium again with a bright smile after taking gold for winning the 200-meter freestyle. Sarah Sjostrom of Sweden claimed the silver and Emma McKeon of Australia took the bronze. Ledecky, just 19, won her second gold. At this pace, she could challenge Phelps’ medal haul someday. At the other end of Olympic Park, the US women’s gymnastics team captured a second straight gold with a high-flying and dominating performance. The triumph was never in doubt, their score of 184.897 at the Rio Games was more than eight points clear of the field. The day was capped by the 19-year-old Biles, a fan favorite, whose boundary -pushing floor exercise showed just how far ahead they are of everyone else.

GOLDEN GIRLS

Biles, Lauren Hernandez, Gabby Douglas, Madison Kocian and Aly Raisman also gave retiring national team coordinator Martha Karolyi a fitting send off with powerful performances on all the apparatuses. The golden girls dubbed themselves “The Final Five” in honor of Karolyi’s retirement at the end of the Olympics and the fact that the format is changing for Tokyo in 2020 so that only four team members will take part in the team competition. The normally stern Karolyi broke down in tears when she was told of the nickname the team adopted. “I think at this moment we can say that that the United States dominates the world of gymnastics,” Karolyi said. Russia took the silver medal and China earned bronze.

SOUR SERENA

Serena Williams shanked shots all over the court in getting upset by Elina Svitolina of Ukraine. The top-ranked American won’t get a chance to defend the gold she won in London. Williams looked out of sorts and irritated, accumulating 37 unforced errors. She had five double-faults in one game alone in the 6-4, 6-3 loss to the 20th-ranked Svitolina. Williams wiped her forehead, picked up her rackets and headed back quickly to the locker room. Svitolina, who had never before played in an Olympics, smiled and stuck her arms out in front of her, palms up, as if waking up from a dream.

MEDAL STRIPPED

A Ukrainian javelin thrower was stripped of his silver medal from the 2012 London Olympics, becoming the latest athlete disqualified after the retesting of stored doping samples. Oleksandr Pyatnytsya tested positive for the steroid turinabol and was retroactively disqualified from the London Games and ordered to return his medal, the International Olympic Committee said. — AP
