to the cities in which the team plays. Rivalries The club's main rivalry was against the Charleston Battery, going back to the Islanders' first year in the A-League. Charleston was the first team the Islanders beat and since then the Islanders have routinely beaten or tied Charleston. In 2006, Charleston stopped the Islanders' playoff run, giving them their only victory in the series. In 2007, the Islanders beat the Battery in the last game of the season, stopping Charleston's hope for a playoff berth. The Islanders currently have a record of 10 wins, 1 loss and 7 ties against their South Carolina rivals. From 2008, the Islanders have met with the Rochester Rhinos in the USL-NASL playoffs with the Islanders eliminating the Rhinos from the series in both 2008 and 2009. The Islanders' main rivals within Puerto Rico are Club Atlético River Plate Puerto Rico. Their rivalry dates back to around the year 2005 when River wanted to join the USL, but the Islanders had territorial rights in Puerto Rico and they didn't allow River to join. Ever since then River Plate's front office, fans, and some players have had a grudge against the Islanders. The rivalry is a very special one though because the teams had never faced in neither an official nor an unofficial match until 2010, even though the rivalry started way before then. With the Islanders joining the Puerto Rico Soccer League, their rivalry is expected to become into the first Puerto Rican Football Classic or "El Clásico Boricua". Their first two matches took place in the Supercopa DirecTV 2010 finals in 2010. River won both games and went on to win the championship. Puerto Rico Islanders C The Puerto Rico Islanders C is the club's U-20 team. It participates in the Puerto Rican 2nd Division, with the goal of developing players from PRISA with extraordinary potential so that they can eventually make the jump to either the Islanders or Bayamón FC. Puerto Rico Islanders Academy The Puerto Rico Islanders Soccer Academy or PRISA was founded in 2006 and it is made up of U6, U8, U12, U14, U15, U17 youth teams and the Islanders C squad (U20). In 2008 the Islanders opened another academy in the northern city of Arecibo under the PRISA umbrella called the Arecibo Islanders Soccer Academy, which is composed from U5 to U20 teams.
