Newly promoted Asteras Tripolis, a rapid climber up the country’s soccer divisions in recent seasons, stunned visiting Panathinaikos 1-0 yesterday for the club’s first-ever win in the country’s top-tier league. Brazilian striker Rosario slotted in the home team’s winning goal early in the second half to give his club a mid-table placing with four points after four rounds. Later last night, frontrunner AEK, on nine points from three games, was due to defend both its top spot and its 100 percent record against Panionios, two points behind. In one of two games played Saturday, defending champion Olympiakos closed in on top spot with eight points from four games after beating visiting Apollon Kalamaria 1-0. In Saturday’s other game, PAOK drew with OFI 2-2. In the round’s other games, all played yesterday, it was: Ergotelis-Aris, 0-1; Iraklis-Veria, 1-1; Xanthi-Atromitos, 0-1; Larissa-Levadiakos, 3-3.
