• Rafael Nadal says last month's Australian Open final was his worst moment on a tennis court. He also says his back is healing.
The Spanish star, who sustained a back injury in the final of the year's first Grand Slam tournament, said it had been a bit harder to recover from the loss in Melbourne than from other defeats.
"The soul is good. It wouldn't be right to say I was not well after all the things this life has given me. I am a person that takes losses very well, I always have been, and I really do not think about them anymore after a few hours. This time it's taking me a little more," Nadal said.
• Nadal picked up the award for the best male Spanish athlete.
• It was bound to happen: Ivo Karlovic fired down a record-tying 44 aces in his win over Daniel Brands, 6-7 (4), 7-5, 7-6 (3), in Zagreb.
