Alonzo Mourning leaned near his wife's belly before he left for the Olympics and told their unborn daughter not to come early.
She didn't listen, but Mourning made it to the hospital in Miami just in time anyway.
After more than a 19-hour trip from Sydney, he arrived only 17 minutes before the couple's second child, Myka Sydney, was born Friday.
Mourning's wife, Tracy, was scheduled to have labor induced Saturday, but she had begun having light contractions early in the week.
Mourning left Sydney Friday morning on a 14-hour flight to Los Angeles, where he was met by the plane of Miami Heat owner Mickey Arison for the five-hour flight to Miami.
