The NBA became the first league to certify Jay-Z to represent players, according to the Sports Business Journal. Though the NFL has resisted Jay's best efforts thus far, the NBA welcomed Hov back into their arms. 

Jay-Z and Roc Nation Sports President Juan Perez have been granted certification by the NBPA to represent NBA players in contract negotiations with clubs. The NBPA is the first sports union to grant Jay-Z certification. Jay-Z, Perez and Roc Nation Sports VP Rich Kleiman also applied for certification with the MLBPA, and a decision on those applications is expected soon.

Jay-Z launched Roc Nation Sports on April 1 with the intent to create a full-service sports agency which represents players in all of the major sports. Anyone can represent athletes for marketing, but in order to negotiate playing contracts, agents must be certified by the unions that represent players in the NBA, NFL, MLB and NHL.

Count it as another win in Jay-Z's dominant 2013.

UPDATE: Jay has been certified by MLB.
