They have been drawn against the sixth seeds in qualifying, Australian Priscilla Hon ranked 95 and Dutch player Arantxa Rus (128) and will play tonight New Zealand time.
"It's just a big opportunity that we didn't think we would get a couple of months ago, so honestly we are just really really pumped."
Routliffe played against Rus and Spaniard Silvia Soler-Espinosa at Auckland's ASB Classic in January and with fellow Kiwi Paige Hourigan lost a close match.
"We know both opponents pretty well which is good." Routliffe said.
The Canadian based Kiwi hasn't played any grass court tournaments since playing at Junior Wimbledon when she was 17, six years ago. However she has had plenty of practice over the past couple of days in London and feels it will suit her game.
"I feel good and I am not worried about the grass it suits me (she has a big serve) and if you are serving well you are going to get free points on grass." Routliffe said.
