Peamount United made it three wins in a row to secure their place at the top of the SSE Airtricity Women's National League table.
The champions still have a game in hand while Athlone Town were edged out by Wexford Youths in series four of the SSE Airtricity Women's National League.
It was a real battle in Ferrycarrig Park as Athlone conceded a penalty and had two players sent off but will feel that they could have got something out of the game after losing 1-0 to Wexford Youths.
Kylie Murphy fired in the game-winning penalty on 80 minutes after she had been fouled, but Athlone had already lost midfielder Muireann Devanney by that stage to two yellow cards.
Defender Fiona Owens would soon follow in leaving the pitch early as Athlone's frustrations were clear to see.
For Wexford, they will focus simply on the fact that this is their second win of the season and it elevates them up to second place in the table at a time when they cannot afford to be left behind in the title race.
Meanwhile Peamount moved top of the league after a 3-0 victory away to Bohemians in the Oscar Traynor centre.
The Gypsies shut the champions out until the 65th minute, albeit an earlier goal was ruled out for offside and that required a huge team effort as Peamount came through everything at Bohs.
In the end that bit of quality that the League leaders possess told as Tiegan Ruddy got them started with a fine finish before Eleanor Ryan-Doyle curled in a superb free-kick.
Then a quick breakaway ended with Becky Watkins converting at the back post to seal the victory, but Bohs know that if they can defend like they did for the majority of this game then it will help them moving forward.
Elsewhere DLR Waves scored a 1-0 victory over Cork City in Bishopstown as Cork still chase a maiden league win.
Manager Ronan Collins will be able to pick out plenty of positives from his team's display at Turner's Cross, where they were ultimately undone by Jessica Gleeson 27th minute rocket free-kick.
DLR did enjoy some possession in the opposition's half and went close on several occasions to adding a second goal, but Cork battled hard and stood firm.
For DLR, this result is a big step forward as it proves that they can come out on top in tight battles especially away from home and that will surely boost their confidence.
While, Four goals within six minutes left Treaty United dazed and confused at Eamonn Deacy Park as Galway WFC scored a 4-1 victory.
The 11th minute opener from Galway’s Lynsey McKey was quickly capitalised on with as four minutes later Savannah McCarthy connected with a corner kick to power home a header.
60 seconds later Shauna Brennan made it 3-0 from the back post before Rachel Kearns notched in her sixth goal of the season making it 4-0 on 17 minutes.
Treaty did pull one back through Áine Walsh's fine strike 13 minutes from time.
