Jake Livermore struck in the 79th minute to reduce the 'Reds' 2-0 advantage gained through Danny Ings and Mohamed Salah.
However, West Brom would draw level ten minutes later through their big striker.
Liverpool gave away a needless free-kick down the left wing which Chris Brunt proceeded to whip into the box.
Rondon timed his run to perfection, getting in front of his marker to head the ball past opposing goalkeeper Loris Karius and equalise for the 'Baggies'.
