Ruben Mendoza became a central figure in soccer in Granite City and the Metro-East Region through his work as a player, coach, referee, and community organizer. Raised in Granite City's Lincoln Place neighborhood after learning the game while living with his family in Mexico, he played ten seasons in the St. Louis Major League, the St. Louis Municipal League, and the St. Louis Soccer League. He was a three-time member of the US Olympic Soccer Team, starting in 1952 and 1955, and also played on the 1954 and 1958 US World Cup Teams in two World Cup qualifying tournaments. Known as a highly skilled forward, he became renowned for the flashy "Mendoza Kick," now more commonly called the bicycle kick. After a knee injury forced his retirement in 1960, he returned to Granite City and began organizing neighborhood boys into teams, which grew from pickup games into broader competition with teams in St. Louis. By the mid-1960s he had worked with the Granite City YMCA and School District #9 to create formal programs for young children and high school players, while also helping establish and support soccer programs across the Metro East. For the next three decades he remained a staple on the pitch, inspiring generations of players and helping build a soccer culture that contributed to Granite City High School's 11 state championships and to players advancing to professional careers in the United States and Europe. His influence helped make Granite City and the Metro East enduring communities of soccer enthusiasts, and he was honored in both the Granite City Sports Hall of Fame and the St. Louis Soccer Hall of Fame while also being remembered as a devoted husband and father of six children.
