Leading 2-1 in the series, the SA team started like a house on fire, moving the ball beautifully around the park and threatened to overwhelm Chile the same way it did just 20-odd hours before.
The momentum soon faded as South Africa struggled to put the ball behind the net.
The many missed opportunities came back to bit South Africa as Chile's striker Manuela Urroz got a tip-in off captain Camila Caram's conventional hit at a penalty corner in the 52nd minute.
The last eight minutes witnessed frenetic action but Chile emerged unscathed to retain their 1-0 lead to square the series 2-2.
SA will have to pick themselves up quickly, as they host Belgium on Wednesday.
