Apollon Kalamaria, where Egyptian midfielder Amr El-Halawani plays, edged 1-0 past Ahmed Magdi's Atromitos in the Greek National League A clash on Sunday. Merkourios Karaliopoulos scored the only goal of the game in the 13th minute to secure the victory for the home side. El-Halawani did not appear for Kalamaria, while Magdi started the game for Atromitos before being substituted ten minutes before the end. Kalamaria leap-frogged Atromitos in 10th place on 35 points, while the latter are 11th on 34, seven points off the relegation zone. However, both teams secured remaining in the first division 2 weeks before the end of the season. On the other hand, Olympiakos Piraeus clinched their third successive championship after beating Kerkyra 3-1. The Greek giants made it nine in ten years after they reached the 67th point, leading second-placed AEK Athens by six. Despite the fact that AEK still have the chance to level on points with Olympiakos, but the latter ascend in the head-to-head match record with a win and a draw.
