The volleyball league saw its regular season end on April 2 with Iraklis finishing first and Olympiakos snatching the second spot from Panathinaikos and PAOK at the very end.
Iraklis defeated Ethnikos Alexandroupolis 3-0 and will now enjoy a home advantage throughout the playoffs, in which the Thessaloniki team will first face crosstown rival PAOK.
The latter ended fourth as its 3-0 loss at Kifissia forced the club to drop two places, just a few days after beating Iraklis at home.
Olympiakos managed to finish second after beating Panathinaikos for the fourth time this season, in as many games. Panathinaikos ended third, which means the two sides will now meet again in the league semifinals, with Olympiakos having the home advantage. The playoffs begin on April 6.
Panathinaikos took the first couple of sets and had seven match points in the third set to win the match at Rendi, but Olympiakos fought back to win the game in the tiebreak with a 3-2 score.
Epikouros Polichnis followed Panellinios to the A2 division, despite its 3-2 surprise win at EA Patras, which will again be representing Greece in the Challenge Cup.
Apollon Kalamarias beat Panellinios 3-0 to maintain its A1 status for one more season, while Lamia saw off Aris 3-1 at home and finished sixth. It will represent Greece in the Balkans Cup.
Finikas Syrou and Pamvochaikos are set to advance from the A2 division.
