Novak Djokovic and Rafael Nadal took two very different paths to the fourth round of the French Open on Friday.
Djokovic, the defending champion, was extended to five sets by Argentina's Diego Schwartzman, ultimately winning 5-7, 6-3, 3-6, 6-1, 6-1. The second-seeded Serb sealed victory on his first match point with a forehand winner down the line, completing the win in 3 hours, 19 minutes.
He gave Schwartzman a hug and a pat on the head at the net -- and then joined in the applause as the Argentine player walked off Court Philippe Chatrier.
"I was expecting a difficult game with a lot of rallies from the baseline, because the conditions are heavy," Djokovic said moments after his win. "I want to congratulate Diego for a great battle, because he played very well."
Djokovic's biggest problem Friday was himself. He wound up with 55 unforced errors to 43 winners and had all sorts of issues on his backhand wing, which produced 33 of those miscues, all under the watchful eye of new coach Andre Agassi.
Djokovic's attitude also led to a tense moment with the chair umpire in the fourth set.
In the fourth set, with Djokovic leading 4-0 and serving at 30-all, he was given a fault by umpire Carlos Ramos for multiple time violations. After the ensuing point, Djokovic stared in Ramos' direction. Moments later, just about to face a break point, Djokovic yelled at himself, mostly in Serbian. Then, facing Ramos, Djokovic briefly lifted his racket overhead, before using it to flip a ball backward toward a ball boy.
That's when Ramos interrupted, announcing a code violation warning for unsportsmanlike conduct. Djokovic walked over and barked: "What's wrong with you? What did I say? What did I say? What did I say? Why did you give me warning? What, do you understand Serbian?"
Ramos had trouble getting a word in edgewise but responded: "Because of what you did. The gesture you made with the racket. This is not acceptable."
Djokovic: "Did I hit the ball in your direction?"
Ramos: "No, you did not."
Djokovic: "Did I hit it? Why did you give me a warning?"
Ramos: "Because of your attitude."
Djokovic: "What attitude, man?"
When play resumed, Djokovic missed a forehand to drop that game. He would win 8 of 9 games the rest of the way and continued his streak of never having lost to an opponent outside the top 40 of the ATP Rankings (now 35-0) at the French Open.
Schwartzman needed some treatment to his back late in the fifth set.
Djokovic earned his 58th career match win at the French Open, tying Guillermo Vilas for third among men in the Open Era.
Also, it looks like Andre Agassi will be coaching Djokovic at least through Wimbledon.
"If he wants me there, yeah, I will come," Agassi told his Becker in a Eurosport interview in Paris when asked about the next Slam at the All England Club in July.
"It's a lot of responsibility so whatever's practical and achievable -- 100 percent I will make the effort."
Nadal, meanwhile, dropped just one game on his way to a straight-sets victory over Nikoloz Basilashvili in his third-round match on Court Philippe-Chatrier.
It was Nadal's 100th best-of-five-sets match on clay. He has a 98-2 win-loss record, and he improved to 14-0 in third-round matches at Roland Garros.
With the rain clouds rolling in, Nadal seemed keen to get his third-round match over as quickly as possible, and the No. 4 seed took 90 minutes to win 6-0, 6-1, 6-0.
It was the 15th and 16th time that he's held an opponent without a win in a set at the French Open during his career.
"I don't know if it was perfection," said Nadal, who turns 31 on Saturday. "I went on court thinking it was going to be a tough match. ... I believe I played the best match since a while."
American Steve Johnson, still grieving the recent death of his father, lost to sixth-seeded Dominic Thiem 6-1, 7-6 (4), 6-3.
The 25th-seeded Johnson had burst into tears after his second-round victory over Borna Coric on Wednesday, but there was no such display of emotion after his loss to Thiem, who spoke to Johnson at the net and gave him a consoling hug.
Fifth-seeded Milos Raonic advanced to the fourth round when opponent Guillermo Garcia-Lopez retired from the match with a left thigh injury.
Raonic was leading 6-1, 1-0 when Garcia-Lopez stopped. The Spaniard had already received treatment at the end of the first set.
It was the second retirement of the day. David Goffin was forced out with an injured right ankle.
Pablo Carreno Busta, the No. 20 seed, earned his first win over a top-20 player in a Grand Slam with a 7-5, 6-3, 6-4 victory over 1tth-seeded Grigor Dimitrov.
Busta, who had been 0-7 vs. top-20 players in Grand Slam events, has never reached the second week of a French Open -- the only Slam where he has yet to do so.
In men's doubles, third-seeded American twins Bob and Mike Bryan lost in the second round, beaten by Sam Groth of Australia and Robert Lindstedt of Sweden 7-6 (4), 6-3.
The Bryans have won a record 16 Grand Slam men's doubles titles as a pair, including two at the French Open, in 2003 and 2013.
Only two rounds into the tournament, the top four teams all already are out of men's doubles. The top two pairings lost in the first round of the French Open for the first time in the Open era, which began in 1968.
