Highest level tourney they've ever entered, save last year's UK grass. I think that the AO champs are quite surprised to be so; Safarova has't won another doubles match in 2015, W/L 6/3: without 2000 points from Oz, BMS would be ranked below Anna and Joss. So they might have a decent chance.
Not great, but at least they gave it a go, and gained some great experience. I'm sure they're counting down the days until they get on the green stuff.
