Ulster Elks trail Irish Hockey League leaders Hermes by four points after a 2-2 draw at third placed Railway Union.
The top two sides will meet in Dublin on Sunday as the women play two rounds of matches over the weekend.
Hermes made it six straight wins to start the season with a 3-0 victory over Cork Harlequins while Ards pulled away from the bottom of the table after a 3-1 win over UCC at Londonderry Park.
Pegasus made it two wins in a row by beating UCD 4-1.
There was plenty of intensity on show in south Dublin as the Elks remained unbeaten in their first six games of the season.
They took the lead in the ninth minute when Rebecca Barry's ball into the circle found an unmarked Jessica McMaster and the 18 year-old provided a composed finish.
However just before the end of the first period Railway Union equalised when Julia O'Halloran knocked in a rebound.
McMaster's second of the game just after half-time restored the lead for the Elks but again they didn't hold on to it for long as Hannah de Burgh Whyte ripped a shot past Elks goalkeeper Rebecca Davidson from a well worked penalty corner.

The final period was feisty as both sides chased the winner and both had chances with Megan Frazer slamming her stick into the ground after missing the target but the Elks will be indebted to Davidson who made two superb saves to preserve a point including a stick tackle on Niamh Carey with the last play of the game.
Hermes beat Cork Harlequins 3-0 with two more goals for Irish international forward Anna O'Flanagan giving her 11 this season.
Ards continued to pull away from the bottom of the table with a 3-1 home win over UCC. Chloe Brown, Becky Weir and Kerry Harvey got the goals as the home side recorded their second win of the season.
At Queen's Pegasus went behind to a Aisling Naughton goal for UCD after just four minutes but Vanessa Surgenor equalised from a penalty corner to make it 1-1 just before half-time.
After the break Pegasus took control with further goals from Hannah McMillan, Alex Speers and a second for Surgenor.
Connacht side Greenfields are still pointless at the bottom after losing 4-0 to Pembroke Wanderers.
Pegasus are at home again on Sunday against UCC while Ards travel to Pembroke.
