Roger Federer says that it was Martina Hingis who decided not to play mixed doubles with him at the 2012 Olympics. Federer called his now-retired fellow Swiss to clarify the situation because she was consistently being asked about it, even though she never indicated she had a desire to play on tour again.

"It was a bit unfortunate for her really because all of a sudden she was in this pressure situation wanting to get more information that she didn't have," Federer said. "She's a wonderful person. I've looked up to her in a big way because she's only a year older but made the breakthrough so much earlier. For me, it was the only player I could imagine playing mixed together with at the Olympics. I knew it was going to be difficult for me in terms of playing so many matches, than her coming back out of retirement. I just wanted to see what was her feeling. She was the one to basically also tell me I should focus on winning singles and defending my doubles. She's very happy staying in retirement. She basically took the decision for me, which was very nice of her."
