Would have thought so. I would have probably thought Doog and I would play the singles and you would team up with Doog for the doubles.
As it stands its going to be me and Callum in both the singles and doubles tbh... Doubles is going to be more interchangable than the singles, but we're the only two to actually have played in a doubles team out of the four so far, and we share the same preferred surface. We haven't however, picked up any doubles ranking points between us. Storer, if you want to get in on the Davis cup I would suggest finding a doubles partner for the next regular season tourny.
Also, it wouldn't take a whole lot for anyone to overtake Callum in the singles rankings, he only has 5 points atm...
