Where Federer's anger is aimed still is uncertain.

Tennis.com speculated Wednesday that Federer and Wawrinka have put the details surrounding their match behind them. Wawrinka reportedly complained to the chair umpire about Mirka Federer, Roger's wife, whose boisterous cheering for her husband angered Wawrinka.

Mirka reportedly accused Wawrinka of whining.

But if Roger Federer and Wawrinka haven't made up, then Federer's comments earlier this week might have thrown gasoline on the fire.

"Stan should have finished that match at 5-3," Federer said, according to tennis.com. "I wouldn't have had a back problem and we wouldn't have had the situation we had."

The report speculated that Federer seemed more irritated at the chair umpire, Cedric Mourier, for confirming the tiff between Mirka and Wawrinka.

The Telegraph reported that Mourier told the Swiss website 20 Minutes that "I noticed that Stan was getting irritated when he was at the same end as Roger Federer's team. I asked him what had happened. He said 'She talked to me.' And I realized he was upset with Roger's wife."

In an interview with BBC tennis correspondent Russell Fuller, Federer said, "The umpire is not allowed to do an interview in the first place. If he mentions my wife's name or not, it doesn't matter."

Wawrinka was in agreement with Federer about Mourier's unnecessary involvement in their match, criticizing Mourier's performance.

"I don't think the umpire was doing great job," Wawrinka said, as reported by the Telegraph. "As you can see also at the beginning of the third set with the overrule and everything (when Mourier mistakenly changed a linesman's call but Federer failed to hear his intervention, causing a separate argument), it was quite a mess already."
