In 1977, Glenn Burke, a rookie outfielder in Major League Baseball (MLB) with the Los Angeles Dodgers, lifted his arm high above his head and slapped palms with his teammate Dusty Baker to celebrate a milestone home run, marking what is widely regarded as the first documented instance of a high five. But perhaps even more fascinating than the high five’s impromptu, exuberant birth is the story of its inventor: MLB’s first openly gay player. The extraordinary story of a largely unsung pioneer, The High Five revisits Burke’s life, a man who quietly challenged traditional notions of masculinity decades before lesbian, gay, bisexual and transgender athletes in professional sports became headline news.
