Jay Z and Robinson Cano

*Jay Z, an official sports agent for all of five months, currently finds himself in hot water with Major League Baseball’s Players Association over a $34,000 watch he gave to New York Yankees second baseman Robinson Cano.

Baseball’s union is investigating whether the gift, a Shawn Carter Classic Fusion watch by Hublot, violated the rules. MLBPA regulations forbid agents from offering “any money, or any other thing of value” to players in order to persuade them to continue using their services. Agents can give gifts to players who are already their clients but the union must be notified in writing of any gift exceeding $500.

Cano, who left agent Scott Boras in April to join Jay Z’s Roc Nation Sports, received the watch during an Oct. 22 party in Belgium celebrating his 31st birthday, according to media reports and postings on Cano’s Instagram. Jay Z, who reportedly helped design the timepiece, had performed in Antwerp the previous night.

The National Basketball Players Association and the MLBPA certified Jay Z as an agent in June. Several sports stars — including Kevin Durant of the NBA’s Oklahoma City Thunder and Jets quarterback Geno Smith — have signed on with his agency since then.

Meanwhile, Hov has a history of showering clients with a lavish gifts. He surprised the WNBA’s No. 3 pick, Skylar Diggins, with a $100,000 Mercedes Benz when she graduated from Notre Dame in May.

Cano is represented by Creative Artists Agency as well as Roc Nation. Cano is reportedly seeking a 10-year, $310 million contract from the Yankees. The club presented Cano — now its biggest star — a one-year, $14.1 million qualifying contract on Monday.
