Olympiakos and Panionios will once again fight it out for the title of the men’s water polo championship, after advancing last night to the league finals. A few weeks after their face-off in the Greek Cup final, which Olympiakos won in extra time, the two favorites will begin their trophy series on Monday, June 14, at Olym-piakos’s home pool in Piraeus. Both clubs advanced from the semifinals, sweeping their opponents with two wins in as many games. Olympiakos saw off Vouliagmeni 9-7 away after its hard-fought 9-6 first win on Saturday, and Panionios defeated PAOK 6-4 in Thessaloniki. The Nea Smyrni club had also won at home two days earlier 21-10. Surprise package Palaio Faliro will play in Europe next season as it stunned favorite Panathinaikos to finish fifth in the league. Last night it won 17-16 in the penalty shootout at home following its away win on Saturday with a 7-5 score.
