Club Atlético San Isidro
Argentine sports club
The Club Atlético de San Isidro (mostly known for its acronym CASI) is an Argentine amateur sports club based in the city of San Isidro in Greater Buenos Aires. Originally established as a football club, San Isidro has gained recognition for its rugby union team, holding a record of 33 Torneo de la URBA championships. The senior squad currently competes at Top 12, the top division of the Unión de Rugby de Buenos Aires league system.
San Isidro has also a notable past in football, with 26 consecutive seasons (from 1906 until 1931) playing in Primera División, the top division of Argentine football league system until the club disaffiliated from the Association when the sport became professional in Argentina. Until then, San Isidro had achieved some international titles such as three Copa de Competencia Jockey Club, one Copa de Honor Municipalidad de Buenos Aires and one international Tie Cup. Nowadays, football is practised at the institution with youth and senior amateur competitions for men and women.
The field hockey section has women's and men's team competing at Metropolitano championships organised by the Buenos Aires Hockey Association.
Apart from rugby, hockey and football, other disciplines hosted by San Isidro are artistic gymnastics, basque pelota, bowls, gaelic football, golf, squash, swimming, taekwondo and tennis.
History
Beginning and football years
At the beginning of 1902, a group of young men started to practise football in a field placed in the lowest part of the hill (called "la barranca" in Spanish). That land was the property of María Varela de Beccar, an aristocratic woman that allowed them to play there.

Why this record matters
The phrase “argentine sports club” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q922496. None of the 2 selected statements returned an explicit reference. The first chronological checks are 1906, 1931 and 1902.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
