Within 24 hours, Roger Federer went from being some stodgy 31-year-old dad to a hip tennis player who tweets and holds question-and-answer sessions on another social media platform.
Asked by Reddit user "Trikskier" about the most difficult matches of his career, Federer listed five:
1. 2003 Davis Cup semifinal vs. Lleyton Hewitt, who came back to beat Federer 5-7, 2-6, 7-6 (4), 7-5, 6-1 to help Australia eliminate Switzerland.
2. 2012 London Olympics semifinal against Juan Martin del Potro. Federer won 3-6, 7-6 (5), 19-17.
3. 2009 Wimbledon final against Andy Roddick. Federer won 5-7, 7-6 (6), 7-6 (5), 3-6, 16-14 for his record 15th Grand Slam title.
4. 2005 ATP World Tour Finals championship match against David Nalbandian. The Argentine rallied to win 6-7 (4), 6-7 (11), 6-2, 6-1, 7-6 (3), ending Federer's 35-match winning streak overall and 24-match winning streak in finals.
5. 2008 Wimbledon final against Rafael Nadal, who prevailed 6-4, 6-4, 6-7 (5), 6-7 (8), 9-7. "One of the greatest matches I've been a part of," Federer said on Reddit.
Notably absent? His five-set losses to Novak Djokovic at the 2010 and 2011 U.S. Opens after having match points in both. That's OK. Those two probably still sting a little bit.
But enough of the serious stuff. Whether he meant to be or not, Federer was pretty funny throughout his Q&A session and seemed to be genuinely enjoying himself. He cracks jokes like a dad. It's great. Here are five of my favorite Q&A exchanges:
happylookout: Hey Rog. Can I call you Rog?
AlfaAlfalfa: What is your reaction to this?
Federer: For you baseball fans out there: Strike 1.
Atifinthenight: My question is: at this point in your career, are there any records or achievements that you still really want?
Federer: There are some great new CD's out that I haven't bought yet. But in terms of tennis records: Any record is welcome. 8 Wimbledon would be great. I'd also love to win another ATP World Tour final. And getting back to World #1
youngjabberwocker: Since players like you, Nadal, or Djokovic have all started off as young players, what advice do you have for young tennis players who have dreams of going professional?
Federer: Take up football. No just kidding.
Federer45: How do you keep your hair so perfect? Federer: I really don't. I fight it every day like everybody else. But thanks.
