Tennis is quite fertile these days.

Luxembourg star Mandy Minella and tennis star Serena Williams are expecting babies this year. Then there is record-breaking world class Roger Federer who is the dad to two sets of twins.

Add former Number 1-seeded Andy Roddick to the list as he and wife actress Brooklyn Decker are expecting their second child together.

Earlier today, while being inducted into the International Tennis Hall of Fame in Newport, R.I., the 34-year-old thanked his mom Blanche, late dad Jerry, his son Hank, his wife, and most notably, a daughter to come, E! News reports.

“Brook, I don’t know how you juggle it all… You hear a lot of guys find it very tough to walk away from professional sports, but you are the reason my personal transition into a quasi-everyday life has been gratifying and full,” the tennis star said during this acceptance speech. “Hank will someday realize how lucky he is, and our daughter that’s coming will also realize she has the best mother on Earth.”

The couple welcomed their son Hank on August 2015. The pair have been married since 2009.
