What Are COSAT Junior Rankings?
COSAT rankings measure performance in officially sanctioned COSAT Junior Tour tournaments across South America.
They are designed to:
- Structure continental competition
- Identify top regional talents
- Support progression toward international ITF events
COSAT rankings operate separately from ITF rankings but serve as an important preparatory stage.
Age Categories in COSAT
COSAT competitions are primarily structured around:
- U14
- U16
Each category has its own ranking list and calendar of tournaments held across South American countries.
How COSAT Ranking Points Work – Gira COSAT
Understanding the points system is essential for any player competing on the South American circuit. The Gira COSAT operates on a specific grading system where the number of points awarded depends on the tournament’s category (Grade 1 to Grade 4).
These points are crucial as they determine the year-end rankings and qualify the top-performing players for the prestigious COSAT Masters and the European tours organized in partnership with the ITF and GSDF.
Tournament Grades & Points Allocation
Not all tournaments are equal. The number of points awarded depends on the “Grade” of the event:
- Grade 1 & Grade A: These are the highest-level tournaments (like the Banana Bowl or the South American Individual Championships). They offer the maximum points and attract the top South American junior tennis talent.
- Grade 2 & Grade 3: These regional events provide essential points for players looking to break into the Top 100.
- Grade 4: Entry-level international tournaments perfect for gaining initial experience on the tour.
COSAT Points Allocation (Singles)
The following table breaks down the points awarded for each round based on the tournament grade for both U14 and U16 categories:
| Tournament Grade | Winner | Runner-up | Semi-finalist | Quarter-finalist | Round of 16 |
| Grade 1 (G1) | 150 | 110 | 80 | 50 | 30 |
| Grade 2 (G2) | 80 | 60 | 45 | 30 | 15 |
| Grade 3 (G3) | 40 | 30 | 20 | 15 | 8 |
| Grade 4 (G4) | 20 | 15 | 10 | 7 | 3 |
Key Ranking Rules to Remember:
- Best Results: Much like the ITF circuit, the COSAT ranking is calculated based on a player’s best performance over a rolling 52-week period.
- Regional Eligibility: While international players can often participate in these tournaments, the official COSAT ranking is specifically reserved for players representing South American nations.
- Transition to ITF: Success in Grade 1 tournaments is a major milestone for South American juniors looking to transition toward the ITF World Tennis Tour Juniors (U18).
The Race for the European Tour
One unique feature of the Gira COSAT is the “European Tour Qualification.” The top-ranked players in the U14 and U16 categories at the end of the main circuit earn a spot on the COSAT team to compete in Tennis Europe events during the summer. This makes every match in the early months of the year crucial for those dreaming of international exposure.categories.
The Gira COSAT: Pathway to the ITF World Tennis Tour Juniors
Success on the South American junior circuit is the ultimate springboard for young talents. High rankings in the U14 and U16 COSAT categories are often the first step toward earning a spot on the ITF World Tennis Tour Juniors, where players begin competing at the global U18 level.
The Proven South American Performance Pathway:
- National Level: Building a foundation in local tournaments.
- COSAT U14/U16: Dominating the regional stage to gain international experience.
- ITF Junior Tour: Transitioning to the U18 global circuit to earn a world ranking.
- Professional Transition: Using junior success to enter the ATP or WTA rankings.
Pro Tip: Many top-tier COSAT players use their year-end rankings to secure wildcards or entry into prestigious ITF Grade 1 and J200 events, bypassing lower-level qualifiers.
