It hasn't taken Jay-Z long to make his presence felt in the sports world.

After the rap mogul announced the creation of his new sports agency, Roc Nation, and signed New York Yankees infielder Robinson Cano, some people doubted whether Jay-Z could have a significant impact across different sports. And while the Roc Nation venture is still young, all signs indicate that it's going pretty well for Jay-Z.

On Thursday former Notre Dame star and the third overall pick in the recent WNBA Draft Skylar Diggins announced that she had signed with Roc Nation. Diggins is coming off an extremely successful career in South Bend, finishing her career as the school's all-time leading scorer and leading the Fighting Irish to the Final Four in three consecutive seasons.

While it has been hard for some WNBA players to prove their marketability, if anyone can break through to mainstream America, it's Diggins. The guard has proven extremely popular on Twitter, with more than 370,000 followers.

Diggins' announcement comes amidst reports that Jay-Z is pursuing hockey phenom Seth Jones. Diggins and Jones figure to be the faces of their respective leagues for years to come, and scoring both of them could be a huge coup for Roc Nation.
