Jay Z reportedly under investigation for watch gift to baseball star

Rapper-turned-sports agent Jay Z is reportedly under investigation by Major League Baseball Player's Association officials for giving New York Yankees star Robinson Cano a pricey watch as a gift.

The organization's leaders are keen to determine whether or not Jay violated the union's agent regulations by giving the second baseman the $34,000 timepiece from his own limited edition Shawn Carter Classic Fusion Hublot range as a 31st birthday gift last month.

They fear the rapper may have broken a rule that stipulates, "No Player Agent or Applicant shall provide, cause to be provided or promise to provide, any money or any other thing of value to any player, or any person related to or associated with such player, the purpose of which is to induce or encourage such player to use or continue to use any person's or firm's services as a Player Agent, Representative, or Draft Advisor."

Cano joined Jay Z's Roc Nation sports group in April.

According to the MLBPA rules, any gift over $500 must be disclosed to the union in writing, and as a result, Jay Z could face discipline for his actions, reports BleacherReport.com.
