Jay-Z raps about taking Boras client

Jay-Z took one client from Scott Boras. Now he's taking it to Boras in song.

The veteran Brooklyn rapper, who recently began work as a sports agent with his Roc Nation Sports, took a shot at Boras in a song off his new album.

"Scott Boras, you over baby. Robinson Cano, you coming with me," Jay-Z raps on the song "Crown," ESPN.com's Darren Rovell has confirmed.

Jay-Z recently signed away the New York Yankees' slugger from Boras ahead of the second baseman's impending free agency.

The song is off Jay-Z's "Magna Carta Holy Grail" album, which will be released Thursday.

Boras, for his part, doesn't seem concerned about being name-dropped in song.

"I'm a fan of jazz," Boras told ESPNNewYork.com's Wallace Matthews, "and my favorite musician is Bernie Williams. What other musician could play center field for the Yankees and win four world championships?"

Boras also spoke to Rovell, without directly addressing Jay-Z or Cano.

"What I've learned through my time in the business is that you can't worry about external factors," Boras said. "You just have to focus on being the best you can be.

"I've been asked to negotiate all kinds of things. And I don't do that because I am singularly committed to the game of baseball. My company doesn't do anything else."

Roc Nation Sports also represents Kevin Durant of the Oklahoma City Thunder, Geno Smith of the New York Jets and Skylar Diggins of the WNBA's Tulsa Shock.

Jay-Z is certified to represent MLB and NBA players.
