Roger Federer and wife Mirka Vavrinec are expecting twins once again. Medical staff at Universitaets Kinderspital beider Basel have reported that Mirka is pregnant with another set of "identicals", but this time they are boys. Mirka and the babies are reported to be in excellent health, but as with any pregnancy, her health will be closely monitored through term. The due date is September 12th which happens to be the week after the U.S. Open in Flushing Meadows.
According to TwinsTwice.com, if a woman has had a set of identical twins, her chance of bearing another is less than 1 in 70,000. Apparently, the Federers are lucky in many ways.
Maybe the Federer boys will be able to give the Bryan Brothers a run for their money.
