Bak in front
The sides went in on level terms at half-time as Slawomir Nazaruk cancelled out Arkadiusz Bak's opener for Polonia. Bak was on target again on the hour before Marcin Kus clinched another three points in the 81st minute.
But Polonia's city rivals, Legia Warszawa, were pegged back by KS Amica Wronki's Mamia Jikija after Cezary Kucharski had put the champions ahead early in the match.
Wisla Kraków had no such problems with KS Ruch Chorzów, dismantling them 5-2. Maciej Zurawski struck a hat-trick, two of them first-half penalties, while Kamil Kosowski scored twice. Jan Wos took credit for both Ruch goals.
Shock of the weekend
KS Górnik Zabrze pulled off the shock of the weekend by beating Zaglebie Lubin 3-2 in a game which saw players from both sides sent off. Marek Zajac was the first to walk in the 45th minute, to be followed by Górnik goalkeeper Piotr Lech after the break. Adam Kompala struck what turned out to be the deciding goal in the 85th minute.
Pogon Szczecin remain pointless after letting a half-time lead slip in a 2-1 defeat by KS Groclin-Dyskob Grodzisk Wielkop. Pogon went ahead on the half-hour when Dariusz Dzwigala scored with a delightful free-kick but goals from Tomasz Moskala (70) and Grzegorz Rasiak (89) won it for Groclin.
In Saturday's other games, KSZO Ostrowiec beat Garbarnia Szczakowianka Jaworzno 2-1, and KKS Lech Poznan lost 2-1 at Odra Wodzislaw. Today at the GWS stadium, GKS Katowice overcame Widzew Lódz 1-0, Mariusz Muszlaik scoring, in a game held up for 15 minutes by crowd violence.
