Peristeri added another major scalp to its collection this year, as after beating champion Panathinaikos a few weeks ago it defeated Olympiakos too on Wednesday, with the Reds appearing to sink into decay. Meanwhile Panathinaikos thrashed AEK on the road to mathematically clinch the top spot in the regular season with three games left to play.
AEK wasted a glorious chance to make a second consecutive Basketball Champions League Final Four and will have to relinquish its crown after crashing out to Bamberg in the tournament's quarterfinals on Wednesday.
The Greek team won 69-67 on the night at the Nick Galis Hall in Athens, but this was not enough to overturn its four-point deficit from the first leg in Germany.
A freak buzzer-beating triple by Rudy Fernandez had Panathinaikos succumb to Real Madrid in Athens, while a careless Olympiakos is risking missing out of the play-offs after its home loss to Zalgiris Kaunas, as both Greek teams wasted their leads to lose to their visitors, one round of games before the end of the Euroleague regular season.
