Everything Jay-Z does these days comes with a huge splash. He didn't open the Barclays Center with one show; he did eight. He didn't just do a New Years Eve concert; he brought his boy Chris Martin and Coldplay along, too. 

Tuesday, Jay-Z didn't just announce that he was starting a new sports agency, Roc Nation Sports. He also announced Robinson Cano was leaving super-agent Scott Boras and signing with him.

Roc Nation, an entertainment company founded by Shawn Carter, also known as Jay-Z, announced Tuesday that it is getting into the sports representation business through a partnership with Creative Artists Agency (CAA). This arm of CAA will be known as Roc Nation Sports, which simultaneously announced that its first sports client is Cano.

"At this point in my career, I am ready to take a more active role in my endeavors on and off the field," Cano said in a statement. "I am confident that the pairing of Roc Nation Sports and CAA Sports will be essential in helping me accomplish my short- and long-term goals. I am making this important decision now so I can keep my focus on helping the Yankees succeed in 2013, while minimizing any distractions for me and my teammates."

Aside from news New York Yankees fans will surely be happy about, rumors are that Jay is trying to get his own license to be an agent, starting with baseball and eventually moving to basketball and football. He'd have to give up his shares of the Nets to get a license in the NBA.

With the new venture, Jay is expanding his seemingly limitless influence. His musical empire is well-established, and he's used it to influence fashion, politics and sports, becoming the second richest man in hip-hop in the process.

He also knows a thing or two about deals, signing massive contracts with Rocawear and Live Nation. How much money do you think he can get potentially negotiating Carmelo Anthony or LeBron James' final contract?
