Taroona’s patience finally was rewarded on Sunday against Launceston City.
The 2-1 Pirates’ win has put City’s second spot on the Women’s Super League table in serious jeopardy.
The Devils had looked to be Ulverstone’s biggest threat in the statewide title race for most of the season.
But they have collected just six points in their past seven games to fade late for the second straight year.
City have not won a match in its last four appearances.
For Taroona, it was also the first time the club had beaten their nemesis in eight attempts. They had come close over the past three years, but found themselves unable to get over the line.
Taroona striker Sophie Booth looked to break its duck in Hobart, netting a double that appeared to sink the visitors’ chances.
Booth scored inside the first minute of the match and stunned the City defence with a second just three minutes into the second half.
City’s hopes were raised when Taroona surrendered an own goal to cut the lead down to one.
Luigi Gugliotti’s charges pushed hard for an equaliser, but the Pirates held off the late charge for three points.
Just four points separate the two sides on the table.
Ulverstone continued its unassailable lead at the top of the WSL, earning a 8-0 win over mid-table South Hobart.
The North-West club is looking to set a new league record of 21 wins from as many matches heading into the final three rounds.
