TAU Ceramica sealed homecourt advantage in the Euroleague play-off quarter-finals by upsetting Barcelona 84-75 in Catalonia in the first of five matches.

TAU led at the end of every quarter in the Palau Blaugrana, with Pablo Prigioni sinking 17 points and eight assists while his TAU team-mate and league-leading scorer Igor Rakocevic added 15.

The results means the second match will also take place in Barcelona and should the series go to five matches, three will be held on TAU's home court.

Olympiacos beat Real Madrid (pictured) 88-79 in Greece in their first meeting in the final eight.

Theo Papaloukas tied a play-off record with a career-high 13 assists off the bench for Olympiacos, who were ahead throughout until Real fought back to lead by a point going into the final quarter.

However the home side rallied to take the win.

In the evening's other match in Greece, Panathinaikos edged Montepaschi Siena 90-85, while a low-scoring game in Russia saw CSKA Moscow triumph 56-47 over Partizan Belgrade.
