Jo prevailed 6-7, 7-6, 7-6, 6-2 over Ljubicic.
I'm very concerned though, because he kept grabbing his back, his buttock, upper leg... he must be in a lot of pain, and overnight the stiffness is bound to get worse. I'm praying that he recovers for the third round against Sela.
Jo continues to impress me with his fighting spirit. It was also wonderful to hear and see the support of the crowd - he's really won a lot of hearts.
