“Fences,” August Wilson’s 1987 Pulitzer winner, was named best revival of a play and its stars, Denzel Washington and Viola Davis, were named best actor and actress. Washington took the prize for his performance as Troy, a one-time baseball star turned sanitation worker who struggles to reconcile his past and present. Critics drew favorable comparisons with James Earl Jones, who originated this role for which he won the second of his two Tonys. “My mother always says, ‘Man gives the award, God gives the reward,’ ” Denzel said. “I guess I’ve been given both tonight.”
