with El Porvenir, which saw El Porvenir prevail 3–2 on aggregate. In 1921, the team secured promotion to the Argentine top division, making its debut in the 1922 season, where Argentinos finished 6th. In 1925, the Argentinos Juniors moved to its current location in La Paternal neighborhood, acquiring land at San Martín Avenue and Punta Arenas Street and building a stadium with a capacity of 10,000. With the new stadium finished, Argentinos Juniors was runner-up in 1926 behind champions Boca Juniors. The club had also increased its membership to 1,000. In 1927, the two separate football associations were reunified and Argentinos played in a massive 34 team league. Later, the league was expanded to 36 and Argentinos managed to keep its place until 1930. 1931–1966 In 1931 Argentinos joined 17 other clubs in forming a breakaway professional league, a move that marked the beginning of the professional era of Argentine football. In 1934 the amateur league was broken up and Argentina once again had a unified first division. As part of this move, Argentinos Juniors were unified with Club Atlético Atlanta, the season progressed badly, and after 25 rounds the union was dissolved due to financial irregularities in the Atlanta books. Argentinos Juniors played on but finished bottom of the league with only 2 wins from 39 games. Argentinos was allowed to keep its place in the Primera, but succumbed to relegation in 1937 after finishing second from bottom of the table. In 1940 Argentinos enjoyed a good campaign in a new stadium, which ended up in winning the 2nd division, but the club was not allowed promotion because their ground did not meet the requirements of the Primera División, and AFA would not make an exception for Argentinos to play at another ground, even though they had done so for several other promoted clubs in previous seasons. In 1943 Hector Ingunza started playing for the club, and went on to become the top scorer in the club's history with 143 goals in official games between 1943 and 1946. In 1948 Argentinos suffered another injustice at the hands of the AFA. They had qualified to the end of season playoff for promotion to the Primera and were top of the league after 7 of the 11 rounds when a players strike interrupted the competition. AFA eventually abandoned the playoff and gave automatic promotion to the teams that had been relegated
