Harrison and Venus will play the Queens Club tournament in London, Eastbourne and Wimbledon. They will then assess how they are going and make a decision about the North American hard court season with big Masters 1000 tournaments in Montreal and Cincinnati ahead of the US Open.
Venus has risen to 15 in the latest doubles rankings while Harrison is up to 30.
Venus has been given a Wednesday start with Sa at the ATP tournament in S-Hertgotenbosch. Ironically he will play against Indians Purav Raja and Divij Sharan, the players who served for the match against Venus and Harrison in the third round at the French Open.
