Ghana, who is three points behind the Group C leaders, hopes for a chance to qualify for the quarterfinals.
With the stake high, the Africans dominated the first 10 minutes of this afternoon's match at Sir John Guise Stadium in Port Moresby.
Ghana striker Jane Ayieyam caused havoc for the Americans at the left flank with her runs.
Pressure turned into points in the 20 minutes from the boot of Ernestina Abambila.
The striker hit a highball 18 metres out, resulting in a shock goal due to fumbles by the US keeper Cassey Murphy.
But the USA team replied two minutes later from ever reliable captain Mallory Pugh.
She showed her class, turning her first clear touch into a goal, placing the ball out to the right side of Ghana goalkeeper, Victoria Agyei, for the equaliser.
With both nations sharing equal possession of the ball, the final match of the FIFA U20 Women’s World Cup group match is likely to go down to the wire.
