Cork boss Ephie Fitzgerald praised the impact of his subs, as Áine O'Sullivan's two goals gave the Division 1 champions a 2-11 to 1-6 victory over Tipperary at Ardfinnan.
The contributions of subs Sadhbh O'Leary, Orla Farmer and Shauna Kelly got their side over the line as Caitlin Kennedy's goal and Aishling Moloney's points had kept Tipp in touch after a bright start from Cork.
O'Sullivan's late strike sealed both points for the visitors.
"It was a battle today. Winter time makes it hard to perform to the level we'd like to be at but it was a good test," said Fitzgerald. "We were up six points at half-time and Tipp got it back to two. But it was our substitutions that gave us the bit of freshness we needed."
Meanwhile, Róisín Leonard fired a hat-trick of goals as Galway got back to winning ways with a 5-11 to 0-7 win over Westmeath in Mullingar.
The Tribeswomen struck two goals in the space of a minute in the early action with Leonard and Sarah Conneally on target, and it was one-way traffic after that.
Ailbhe Davoren also goaled for the westerners, who recovered from last weekend's loss to Donegal with a solid performance, which pleased their manager. "We didn't really bring a lot of intensity last week but we really brought it today. The attitude was way better," said Tim Rabbitt.
Mayo manager Peter Leahy said his side were disappointed not to have shown their talents as they faltered to a 0-12 to 0-7 loss to All-Ireland champions Dublin at MacHale Park.
Mick Bohan's side were rarely in trouble as they claimed victory courtesy of eight Carla Rowe points.
"I thought we never got out of our shell," said the Mayo manager.
"Whether it was nerves, whether it was the occasion or whether it was playing the All-Ireland champions but we stood off and the girls are in there in the dressing-room now very disappointed," said Leahy after Saturday night's defeat.
