According to the New York Post:
Jay-Z has launched Roc Nation Sports, a full-service sports management company and has signed Yankees star Robinson Cano as its first client.
Roc Nation Sports will be led by the rapper with Juan Perez serving as president. They have partnered with CAA Sports, a division of Creative Artists Agency to co-represent the All-Star second baseman.
“Because of my love of sports, it was a natural progression to form a company where we can help top athletes in various sports the same way we have been helping artists in the music industry for years,” Jay-Z said.
