The superstar rapper, whose duet with Keys was postponed due to poor weather conditions at the first game of the World Series, has revealed that he's "never been that close to the field".
Jay-Z told radio show Mike & Mike In The Morning: "The moment at Yankee Stadium for me, as a kid growing up in Brooklyn, I'm still high off of that.
"But right after that, we got a police escort right to the airport and took a plane straight out... I felt like a kid, the field is beautiful, I never been that close to the field, walking around. I jumped over the centre field fence like I was catching a homerun... Fantastic series, I figure Philly is gonna be tough and we can take it in seven."
He added: "The pitching is incredible, Cliff Lee pitched an incredible game and A.J. Burnett pitched, C.C. [Sabathia] pitched a strong game. Everyone is pitching strong. It's a great feeling [to hear my music at the games]. You got Derek Jeter playing 'Empire State' and A-Rod playing 'Already Home' and Cano [Robinson] playing 'Run This Town,' it's a Jay-Z playlist in the stadium. It's fantastic."
