Djokovic continued his serene start to the competition, as he made light work of Laaksonen on Thursday.
The top seed is enjoying an exceptional winning run in the Grand Slam events:
ATP Media Info @ATPMediaInfo
 @DjokerNole won his 23rd straight #GrandSlam match with a 61 64 63 victory over [LL] Laaksonen and advanced to the 3R @rolandgarros for the 14th consecutive year. #Djokovic converted 6 of 10 break pts. and he next plays [Q] Salvatore Caruso, who upset  Simon 61 62 64.
After taking the opening set 6-1, Djokovic appeared to drop down a few gears and allowed Laaksonen to secure a foothold in the second and third sets. However, the 15-time major champion was able to up the ante when he needed to.
Metro's George Bellshaw noted the top players in the men's draw have yet to be seriously tested:
In the women's draw, there was another scare for Osaka. The 21-year-old has won each of the last two Grand Slam tournaments and is among the favourites to go all the way at Roland Garros this year despite having never previously gone past the third round.
In the opening round, the top seed lost the first set 6-0 to Anna Karolina Schmiedlova and had to survive her opponent serving for the match before she came back to win 0-6, 7-6 (4), 6-1.
A second-round clash between Osaka and two-time Grand Slam champion Azarenka was an exciting prospect, and it did not disappoint.
Osaka again had to come from behind after Azarenka dominated the first set, building a 5-1 lead and eventually serving out for 6-4 after Osaka hit 15 unforced errors.
But the world No. 1 has shown during her remarkable rise that she thrives under pressure, and again she pulled off a superb comeback to get through to the third round.
Having started to find her rhythm at the end of the first set, Osaka edged a very tight second and then took advantage of the momentum to finally finish off Azarenka in two hours, 50 minutes:
Williams made much shorter work of her opponent as she continued her campaign for a 24th Grand Slam title.
Like Osaka, the legendary American had to come back from a set down in her first-round match, but Serena had no such trouble on Thursday.
She was largely dominant against Nara despite the qualifier trading holds with her to 3-3 in the opener.
Eventually, the 37-year-old's superiority told as she broke for 5-3 and served out the set, and she then took the second in fairly routine fashion:
The stats painted a fairly accurate picture of Serena's victory as she claimed three of 12 break points while giving up none, hit 36 winners to Nara's 11 and won 84 per cent of points behind her first serve.
