Mateusz Ponitka delivered an inspired performance for the Poles at the EuroBasket Arena Berlin, notching only the third triple-double at the tournament since 1995 with 26 points, 16 rebounds and 10 assists.

A superb run from Poland in the second quarter built what proved to be an unassailable lead for the underdogs at 54-31.

Slovenia reduced the arrears to 58-39 at half-time, and moved to within one point at 61-60 in the third quarter.

However, Poland rallied, and went on to reach the last four for the first time since 1971 with a 90-87 victory.

Slovenian star Luka Dončić appeared to be limping, and was fouled out with three minutes of the match remaining.

Poland's reward for their upset victory is a semi-final against the Tokyo 2020 Olympics runners-up France, who required overtime to beat Italy 93-85.

Thomas Heurtel provided a crucial 20-point contribution for the French.

Poland are set to face France in the first semi-final on Friday (September 16), before hosts Germany play three-time winners Spain.

Tomorrow is a scheduled rest day at EuroBasket 2022.
