“It’s a great feeling but we don’t want to stop,” Poland guard Lukasz Koszarek said. “We know it’ll be more difficult and more difficult, but we don’t want to stop.”

Mikhail Kulagin scored a game-high 21 for Russia (2-2), which was eliminated from quarterfinal contention. The Russians play their second-round finale on Sunday against Venezuela.

Poland shot only 36 percent, but went 35 for 38 from the foul line.

Poland led by one with 2:20 left when Ponitka drove the lane, stumbled to the floor under the basket and somehow fired the ball out to Aaron Cel in the left corner as he fell. Cel hit a 3-pointer off the improbable assist, putting Poland up 72-68 and kept the lead the rest of the way.

“This is the competitive will, the heart, the toughness of our team — to find a way and keep competing,” Poland coach Mike Taylor said.

Taylor said he thinks the run by Poland in this World Cup, the country’s first appearance in FIBA’s signature event since 1967, will be a spark for growing the game in the country.

“I think it means everything,” Taylor said. “I think the country can take self-confidence from the performance of these players. We can compete. We can do it.”

Russia led 40-29 late in the half, but Ponitka made a 30-footer to beat the buzzer to end the second quarter and cut Poland’s deficit to six going into the break. The Russian lead was still seven late in the third, but Poland ended the game on a 29-17 run.

“It was a very difficult loss,” Russia guard Vitaly Fridzon said. “We controlled the game. … Devastating to lose like that. Maybe we lacked some luck.”

Russia coach Sergey Bazarevich said the free-throw disparity — Russia shot 19, half as many as Poland — was a major factor.

“If you look at the stats, we were better in everything,” Bazarevich said. “In every aspect, we were better.”
