Kyrie Irving scored 15 points and the U.S. men's basketball team survived its second straight strong challenge in the Rio Games, edging Serbia, 94-91, on Friday.

The Americans won their 48th consecutive international tournament game, but it was anything but easy.

Serbia's Bogdan Bogdanovic missed a 3-pointer from the left wing with two seconds left that would have tied it, and Kevin Durant grabbed the rebound to keep the Americans unbeaten. They escaped by 10 points against Australia on Wednesday.

Handshake refused: Middle Eastern politics spilled onto the judo mat Friday when an Egyptian competitor refused to shake hands with the Israeli who beat him.

Islam El Shehaby, a Salafi Muslim, had come under pressure before the games from Islamist and nationalist voices in Egypt to withdraw from the first-round heavyweight bout against Or Sasson.

After Sasson won, he extended his hand. But El?Shehaby backed away, shaking his head. The referee called El Shehaby back to the mat and obliged to him to bow. He gave a quick nod and was loudly booed as he exited.

Straight shooter: American Kim Rhode captured bronze in women's skeet, becoming the first woman and second athlete overall to earn an individual medal in six straight Olympics.

Rhode joins Italian luger Armin Zoeggeler with the distinction.

Easy being green: American diver Abby Johnston doesn't mind competing in the green-tinged water at the Maria Lenk Aquatics Center — except for one little matter. “If my hair turns green, I will send my hair-dye bill to the Olympics,” she said.

Closed in the morning, the pool later was a lighter shade of green and appeared to be much closer to its normal color.

Tennis bronze:Steve Johnson and Jack Sock won the doubles bronze for the U.S., beating Canadians Daniel Nestor and Vasek Pospisil, 6-2, 6-4.

In singles, defending champion Andy Murray of Britain edged Johnson, 6-0, 4-6, 7-6 (2), and will face Japan's Kei Nishikori in the semifinals. The other semi will pit Rafael Nadal of Spain against Juan Martin del Potro of Argentina.

On the course:Marcus Fraser of Australia shot a 2-under 69 for the 36-hole lead at 10-under 132 in the first Olympic golf competition since 1904. He had a one-shot lead over Thomas Pieters of Belgium.

Among the U.S. contingent, Matt Kuchar had a 70 and was at 139, followed by Bubba Watson (67) at 140, Patrick Reed (69) at 141 and Rickie Fowler (71) at 146.

On cruise control: The U.S. routed Canada, 81-51, to clinch Group B in women's basketball.

The Americans won their 45th straight Olympic game after their two lowest-scoring quarters in Rio. They led 36-22 at the half. Diana Taurasi and Maya Moore had 12 points apiece.
