MLB notes: Rapper Jay-Z's agency signs Yankees' Cano

Rapper and recording producer Jay-Z is expanding into sports representation and has signed New York Yankees second baseman Robinson Cano away from Scott Boras to be a client.

Shawn Carter, also known as Jay-Z, and his Roc Nation company have partnered with CAA Sports to form Roc Nation Sports. Cano changed his listed agent with the Major League Baseball Players Association on Tuesday from Boras to CAA Sports' Brodie Van Wagenen.

Cano can become a free agent at the end of the World Series. Boras usually prefers that his clients become free agents to increase bidders and maximize their values, so the change could increase the chance Cano will reach a new agreement with the Yankees during the season.

"CAA is built on a culture of collaboration and this relationship is no different," Van Wagenen said. "Jay and I will both be involved in all aspects of Robinson's representation on and off the field."

It remains to be seen whether the players' association will have an issue with Roc Nation's personnel because of Jay-Z's role in NBA team management and his agreements to perform concerts in venues owned by major league teams and their owners.
