It is currently unknown exactly when Southampton LTA came into being, although records indicate that in 1912 there were 10 member clubs (one of which - South Hants - is still in existence today!). In 1928, SLTA took on the running of the Apsley League, originally started in 1924.
Since then it has been the custodian of this incredibly popular Summer Mixed Doubles league. In the meantime, repsonsiblity was also assumed for the Southampton Winter League and Southampton Adult and Junior Open Tournaments.
