Seventeen goals between them and none conceded, the top four in the Leinster first division all picked up wins on Saturday, a Katie Mullan hat-trick helping leaders UCD to the most comfortable victory of the four, a 7-0 defeat of Corinthian.
Fifth-placed Pembroke Wanderers, though, slipped up away to Trinity, Anna-May Whelan getting the only goal of the game for the students, but Old Alexandra's 3-0 defeat by Hermes means Pembroke still have a four-point cushion.
