Jay-Z has taken his love of sports to the next level by expanding his Roc Nation label and management group to include a sports agency, Roc Nation Sports. The new company made waves by naming New York Yankee Robinson Cano, who had previously been represented by the high-powered Scott Boras, as its first client. Roc Nation Sports is a partnership with Creative Artists Agency, whose own sports arm has 800 athletes. Roc's management division has steadily built a roster of music clients in the past five years, including Rihanna, Timbaland and Deadmau5.
