The two-time U.S. Open champ (he retired in 2002) is playing World Team Tennis this month for the Philadelphia Freedom.
SI: How does it feel to be Australia's most famous stay-at-home dad?
Rafter: Is that what I'm known as in the States? (Laughs.) Well, it was time to have a family. The thing I missed playing tennis was not having a normal life.
SI: At 31, you're younger than Andre Agassi. Do you ever get an itch to return to the tour?
Rafter: The thought comes in my mind every three or six months, but I squash it because I know how much work is required to get there and the pressure that you're under all the time.
SI: What happens if you start rolling over people in World Team Tennis? Won't there be a part of you that will be thinking comeback?
Rafter: Absolutely nil on that, mate. But I am hoping to do exactly what you just said.
SI: Your son, Josh, is two. What if he faces two-year-old Jaden Agassi in the 2025 Wimbledon final?
Rafter: Jaden wins. He's got too many genes over there. I'm fighting a losing battle.
SI: You're about to become a TV host. Tell us about it.
