Federer, the No. 3 seed, dropped a set to Adrian Ungur, but managed to knock off the 92nd-ranked Romanian 6-3, 6-2, 6-7 (6), 6-3. The win gave Federer his record-breaking 234th Grand Slam match win. The Swiss star had been tied with Jimmy Connors for the most wins in Grand Slam tournaments at the beginning of the day.
Djokovic is the No. 1 seed and he breezed past Slovenia's Blaz Kavcic 6-0, 6-4, 6-4. Djokovic has won three-straight Grand Slam titles, but has never gone past the semifinals at Roland Garros. Last year, he lost to Federer in the semifinals, and that loss ended a 43-match winning streak.
The current top player in the world had an uncharacteristic 34 unforced errors on Wednesday, while Kavcic had only 21. Obviously, Djokovic will need to clean that up moving forward.
As for Federer, he went right through his opponent in the first two sets, but missed when he had two match points in the third. He was able to put Ungur away easily in the third.
Federer's career record in Grand Slam tournaments is now 234-35, and he owns a record 16 Grand Slam titles.
If Djokovic and Federer continue rolling as they are now, they will meet in the semifinals again. With the way both guys are playing right now, that could be a fantastic match.
