Both sides struggled to maintain possession through errors but it was the USA who struck next - with a poor piece of ball security leading to a turnover just 15m out from the Ferns’ line, the USA forwards went to work, earning a penalty and scoring through No 8 Rachel Johnson in the 23rd minute from the resulting quick tap to make it 5-14.
There was more trouble to come for the Black Ferns - who stacked up six penalties in a row during some desperate defence. Liana Mikaele-Tu’u was the one singled out and given her marching orders for the second yellow card of the match.
Hawkins kicked the penalty and the USA headed into the sheds at halftime with a commanding 5-17 lead.
The Black Ferns had nine handling errors and conceded seven penalties in the first half - they were going to need to sharpen up significantly if they were to recover in the second.
The USA failed to continue their form from the first half - aimlessly kicking the ball back to the Black Ferns rather than finding touch - and the Ferns took full advantage.
With so many dangerous players on the park - bolstered by the NZ side’s halftime substitutions - the USA gave the Black Ferns far too much possession and Arihiana Marino-Tauhinu eventually crossed for their second try seven minutes into the second half. Holmes kicked the conversion and there was blood in the water at 12-17.
A penalty goal two minutes later from Holmes closed the gap further to 15-17.
By the 58th minute - with the Black Ferns starting to seize control - another well-worked lineout with a crafty shift to the blindside allowed Pip Love to pick and go, and score in the left-hand corner. Holmes added the conversion with a great effort from the sideline and the Ferns had hit the lead at 22-17.
From this point cracks began to appear in the armour of the USA - the Black Ferns were able to sustain phases and were beginning to regularly make the advantage line.
A second try to Mikaele-Tu’u in the 68th minute took the lead to 29-17 and by now they were in total control.
Demant and Du-Plessis scored once each to make the 39-17 scoreline reflective of the “game of two halves” nature of the match.
The Ferns will be pleased with their second-half effort - Demant and Holmes in particular were electric with ball in hand and their replacement front row had the USA under the pump at scrum time.
They were plagued by errors and penalties but the resilience shown to overturn the halftime scoreline was exactly what is required of world champions.
