Nevertheless, Central only lasted one season in second division, returning one year later, after 25 matches won and only 4 lost. In 1950 Central was relegated again after a poor campaign in Primera. As its precedent relegation, Central promoted to the top division one year after being relegated, so the team returned to Primera in 1951. Rosario Central won its first national league title, the in 1971 Nacional championship with Angel Labruna as coach defeating San Lorenzo in the final game. Central had previously beat arch-rival Newell's 1–0 in semi-finals with a goal scored by Aldo Poy, who dove to head the ball before it touched the grass (a way of heading popularly known as ""palomita"" in South America). That goal is still remembered by Central supporters who usually reunite on December 19, to recreate the goal. Many times Poy himself has taken part of the celebration. The second league title for the club came two years later, winning the 1973 Nacional with Carlos Griguol as coach. Some of the most notable players were Poy, Carlos Aimar and Eduardo Solari. The most frequent line-up was: Carlos Biasutto, Jorge González, Aurelio Pascuttini, Daniel Killer, Mario Killer, Carlos Aimar, Eduardo Solari, Aldo Poy, Ramón Bóveda, Roberto Cabral and Daniel Aricó. For the 1974 season, Central acquired striker Mario Kempes from Instituto Atlético Central Córdoba (Kempes and Instituto mate Osvaldo Ardiles were to be reunited in the national team that won the 1978 World Cup). After seven years without titles, Central won the 1980 Nacional with Ángel Tulio Zof on the bench. That team was called "La Sinfónica (the Symphony Orchestra)" because of the exquisite playing displayed by the team on the field. Central defeated Racing de Córdoba 5–0 in the first final game, and lost 2–0 in the second match but proclaimed champion due to goal average. Daniel Carnevali, Juan Carlos Ghielmetti, Edgardo Bauza, Oscar Craiyacich, Jorge García, José Gaitán, Daniel Sperandío, Eduardo Bacas, Félix Orte, Víctor Marchetti and Daniel Teglia was the frequent line-up on the fields. After a few years with bad seasons, the team was relegated in 1984, but returned to first division just one year later after winning the Primera B championship, coached by Pedro Marchetta.
