Head to heads are 2-2. Keys has won their last 2 matches including in August in Rio. She won on a hard court in a third set tie break. One of Mladenovic’s wins was due to withdrawal.
Keys easily won her opening set against Duan in the last round but then lost concentration and let the second set slip away. She pulled herself together and won the deciding set comfortably. She reached the 3rd round last year.
Mladenovic beat a tired Jankovic in the last round. Her recent record isn’t good but her performances have not been terrible. She took the first set from Kerber last week.
Keys wins if she is focused but the sets could be tight as they were in Rio. Back Keys if she gets broken. Keys starts around 1.35.
