What is the BSN?
The Baloncesto Superior Nacional is Puerto Rico’s top-tier professional basketball league and its only one, a closed league of twelve franchises with no promotion or relegation. The 2026 season had two conferences of six — Bayamón, Santurce, Caguas, Carolina-Canóvanas, Guaynabo and Manatí in one; Mayagüez, Quebradillas, Ponce, Arecibo, San Germán and Aguada in the other — under a soft salary cap of USD 1.0m and a hard cap of USD 1.5m.[1] [4]
How does it work?
A 34-game regular season from 21 March to 28 June 2026; the bottom two in each conference are eliminated, the rest play conference semifinals and finals, and the two conference champions meet in a best-of-seven national Final, whose seventh game in 2026 fell on 23 August. Each team may sign three foreign players — refuerzos — with at most six changes before the deadline and two more after it, and an import may only be traded for another import.[3] [4]
Since when does it exist?
The league traces itself to 1929 and a first season in 1930, and celebrated 96 years in 2026. Bayamón’s 2026 title, won 81–74 in Game 7 against Aguada, was the Vaqueros’ 18th and their second in a row; Arecibo, Caguas, Carolina, Quebradillas and Aguada have also won titles in the last decade.[2] [5]

Why does it matter?
The BSN is the highest level of basketball in Puerto Rico, with an import system and salary caps that make its roster spots for foreign players — three a team — a defined professional category. Its 2026 Game 7 led the island’s television ratings, drew 125,000 viewers on YouTube and 12,000 in the arena.[1] [3]
