Sport Boys Association is a professional football club based in the port city of Callao, Peru, competing in the Peruvian Liga 1. Founded in 1927, the club is famously known as 'Los Rosados' (The Pink Ones) due to their distinctive pink and white striped kits. They play their home matches at the historic Estadio Miguel Grau in Callao. The club was formed by a group of young friends and has a deep, working-class identity tied to the Callao region. Their peak era came in the 1980s when they won the Peruvian Primera División championship in 1984, a title celebrated wildly by their passionate fanbase. That team featured legendary figures like goalkeeper Eusebio Acasuzo. In the modern era, Sport Boys have oscillated between the first and second divisions, but they remain a club with a massive and fervent following. The current squad, under manager Mariano Soso, blends youth and experience as they aim to re-establish themselves as a top-flight force. The team culture is defined by an incredibly loyal and vocal fan base, known as 'La Misilera', who create an electrifying and sometimes intimidating atmosphere, making their home ground one of the most challenging venues for visitors in Peruvian football.
