"Singles is the priority for him and after the French Open he goes home for a week and is not playing all the grass court tournaments. With Wimbledon being the best of five sets in the doubles he does not want to play doubles there because it would be a bit taxing on his body for singles." Venus said.
However, he says further down the track they will definitely play more tournaments together.
Venus and Harrison earn 250 ranking points and share €26,110 in prize money for winning Estoril. The result is likely to lift Venus five places to 36 in the rankings when they come out later today.
Venus will play at the Aix en Provence Challenger in France week where he will team with Australian John Patrick Smith. Fellow Kiwis Marcus Daniell and Artem Sitak are also at the tournament.
Venus is holding out hope he might get to play next week's big Rome Masters.
"I have sent out a few messages to some of the other guys to see what their plans are and what they are thinking for Rome and we will just see what happens."
Venus and Harrison are entered into the Geneva ATP tournament for another hit out together before Roland Garros which begins on May the 28th.
