The news that Roger Federer had again become the father of twins was greeted by exclamations and congratulations from many current and former players.
Federer and his wife, Mirka, were already the parents of four-year-old twin girls before the 17-time Grand Slam champ announced on Twitter on Tuesday, "Mirka and I are so incredibly happy to share that Leo and Lenny were born this evening! #TwinsAgain #Miracle"
"Double congrats," responded Feliciano Lopez, while Juan Martin del Potro wrote “Feliciataciones," and said he hoped to see the new arrivals soon.
"Since @rogerfederer likes the @WWE I'm thinking future tag team champs for his second set of twins," said John Isner, who is a big wrestling fan.
Fellow twin Bob Bryan tweeted the names and added, "#thefuture #twinsrule."
Several others noted the doubles potential of the Federer family, now in men's, women's and mixed doubles. The Federer girls have already begun to play tennis. "@Bryanbros [Bob Bryan] @Bryanbrothers [Mike Bryan] records could be in jeopardy," wrote Justin Gimelstob.
"Congrats to the family," said the retired Kim Clijsters, while Bethanie Mattek-Sands observed, "This guy has gotta leave some records for the rest of us. #OverAchiever."
