With smiles, laughter and high hopes, Utah Jazz center Greg Ostertag donated a kidney Thursday to his younger sister, whose kidneys failed in March.

Doctors at Baylor University Medical Center said the transplant was a success and that both Ostertag and his sister, Amy Hall, were recovering well.

"It just clicked, it couldn"t have gone better," said surgeon Robert Goldstein, who also did Mickey Mantle"s liver transplant at the medical center in 1995. "It"s already working wonderfully. She very quickly will start feeling better."
