Sharpe came on as a substitute in the 70th minute and almost immediately put the ball in the back of the net.
Two minutes after coming on, she reacted quickest to a loose ball in the Newcastle box, and side-footed an accurate finish past the goalkeeper to make it 2-0 to Palace.
Sharpe's trademark energy and desire were on show throughout her cameo on Sunday, with her proving to be a nuisance to the Newcastle defence time and time again.
She was the clear favourite with 44.3% of the vote, with fellow goalscorer Kirsty Howat coming second with 14.3%.
Justine Vanhaevermaet had another strong performance in Palace colours, and came in third place with 9.3%
