The Outer Courts - U.S. Open Day 4

While most of the top Americans were in action on the show courts Wednesday, the action on the outside courts did not disappoint.

Here's what to look for on Thursday - Courts 4-17

Court 6: Dominika Cibulkova vs. Kateryna Bondarenko - A second round women's singles match featuring the other Bondarenko Sister and Cibulkova, who chases everything down.

Court 7: Jurgen Melzer vs. Ricardas Berankis - Should be a competitive long match.

Court 13: Kei Nishikori vs. Marin Cilic - Cilic tries to advance to the second round.  Nishikori is a decent shotmaker, could take a set from Cilic.

Court 13: Agnieszka Radwanska vs. Shuai Peng - If Radwanska plays her normal self, she should win.

See you at the courts.
