Castro was born in Montevideo. When he was 13, he accidentally amputated his right-forearm while using an electric saw, which gave origin to his nickname, El manco (meaning "the one-armed", or "the maimed").
Castro began his career in 1923/24 with Nacional and was the first player to score in a World Cup game for Uruguay. At Nacional he won three Uruguayan Championships (1924, 1933, 1934), before retiring in 1936.
1933 Uruguayan Championship
In the 1933 Uruguayan Championship, Peñarol player Braulio Castro scored a controversial goal in the championship match where the ball clearly went out of play, but rebounded off a kinesiologist's medicine cabinet back into play in the build-up to the goal. This turned out to be the only goal of the game, and the opposition, Nacional, felt very hard done by, and three of their players were sent off, for assaulting the referee in annoyance at the goal. This meant that the referee, Telésforo Rodríguez, was unable to continue through injury, so one of the assistant referees, Luis Scandroglio, stepped in, and immediately abandoned the match due to bad light, after seventy minutes.
Over two months later, on 30 July, the League Board decided to disallow the goal, and also rescinded one of the three aforementioned sendings-off (that of Ulises Chifflet). They also ruled that the final twenty minutes would be played at Estadio Centenario, but behind closed doors to try to avoid the same controversy which had plagued the original encounter. The match went ahead behind closed doors, and there were no goals in the twenty minutes. In a highly unorthodox move, two sessions of extra-time were played (the usual allowance would be a single session), the score remained goalless. Nacional's fans remember this game as the "9 contra 11" ("9 against 11") since their team played the remaining 20 minutes plus both overtimes (totalling over 80 minutes) with nine players.
A third playoff was contested on 18 November, and Héctor Castro played a vital role in this match, scoring a hat-trick which meant twice equalising as well as scoring the winning goal for Nacional, in a 3–2 win over Peñarol, which finally settled the Uruguayan Championship, almost six months after the controversial first playoff. This controversial playoff also meant that the Uruguayan Championship of 1933 was bizarrely not awarded until November 1934.
Castro made his debut for the Uruguay national football team in November 1923. He played his final match for la Celeste in August 1935 having played 25 times, scoring 18 goals.
Playing for Uruguay at the 1928 Olympic Games Castro won a gold medal.

Castro died in 1960 at the age of 55, from a heart attack.
