Daryl Homer of the United States won the silver medal in men’s saber, missing a chance to become the first American man to win an Olympics fencing gold medal in more than a century.  Homer, who fences out of the Manhattan Fencing Center and was seeded 10th, beat fencers from Kazakhstan, Germany and Iran on the way to the final.  The gold medal match was aggressive and quick, like most saber matchups. Homer quickly fell behind Aron Szilagyi of Hungary and lost, 15-8. With the silver, Homer became the first American medalist in individual saber since Peter Westbrook won a bronze in 1984.  The last American gold medal for a man in fencing came at the 1904 St. Louis Games in the single sticks event, in which combatants belted each other with long wooden sticks. The winner, Albertson van zo Post, prevailed over a field of three, all of them Americans. — VICTOR MATHER  The American cyclist Kristin Armstrong won her third consecutive gold medal in the individual road time trial on Wednesday, becoming the first person to win the same Olympic cycling event three times in a row.  What’s more, Armstrong — no relation to Lance — accomplished the feat one day shy of her 43rd birthday, which also makes her the oldest woman to have won an Olympic cycling gold medal.  “We’ve been told we should be finished at a certain age, but there are a lot of athletes out there who are showing that’s not true,” said Armstrong, who overcame a nose bleed at the 12-kilometer mark.  Armstrong completed the 29.8-kilometer (18.5-mile) course in 44 minutes 26.42 seconds, just ahead of Olga Zabelinskaya of Russia, who finished in 44:31.97. Anna van der Breggen of the Netherlands won the bronze medal.  Soon after her win, Armstrong got a pat on the back from another athlete who seemed to defy age: Barry Bonds. A cycling enthusiast, Bonds posted an image from the race and wrote, “Congratulations Kristin Armstrong 3 time gold medalist,” on his Instagram account.  Remarkably, Armstrong almost did not make it to Rio. She came out of retirement in 2015, three years after calling it quits. Her latest gold medal was “the most gratifying,” she said. “It was the hardest of my Olympic journeys.” — KEN BELSON  Men’s basketball: The United States had an unaccustomed scare in men’s basketball, beating Australia by only 98-88. The U.S. trailed by 5 at the half and needed some big 3’s late by Carmelo Anthony to win. Patty Mills of the San Antonio Spurs led Australia with 30 points; Anthony had 31 for the United States.  Men’s gymnastics all-around: Kohei Uchimura of Japan, often called the greatest gymnast ever, retained his title. He delivered a 15.8 with a difficult high bar routine to overtake Oleg Verniaiev of Ukraine on the final apparatus. The practically unbeatable Uchimura has also won the last six world championship all-around titles.  No Medal for U.S. Rugby Sevens: The American men lost to Fiji, 24-19, and were eliminated from the competition. The United States missed by the narrowest of margins: Its point differential, plus-18, was just 1 short of that of New Zealand, which grabbed the last spot in the quarterfinals.  Different sports require different body types, right? Volleyball players are usually long and lean. Weight lifters, not so much. So we asked a bunch of Olympians and Paralympians to strip down to their underwear (or whatever they felt comfortable with), so you could try to guess which sport they compete in. How many can you guess correctly?
Here’s our daily roundup of what happened, and what is going to happen, at the Summer Olympics in Rio de Janeiro.
