Jay-Z is sporting a new business hat. 

The hip-hop mogul and New York Yankees fan has signed the team's second baseman Robinson Cano to his latest venture - Roc Nation Sports. 

Cano is the company's first client.  The four-time All-Star is leaving agent Scott Boras to join Jay's team.  Roc Nation Sports is working in tandem with Creative Artists Agency to form a representation division. 

Cano is in the final year of his contract with the Yankees and the two sides have yet to reach agreement on an extension.
