Jo Wilfried Tsonga had to come from a set down to see off Andrey Kuznetsov and book his place in the second round of the French Open.
Tsonga is seeded fifth at the second Grand Slam of the year but he didn't play like it in the first set as he picked up just a single game.
His serve was not the booming weapon that we have come to expect and Kuznetsov hit some blistering returns that immediately put the Frenchman on the back foot.
However he looked to settle into the match in the second set and a single break was enough for him to level the match at a set a piece.
And while Kuznetsov continued to battle he wasn't having the same success as in the opening set as Tsonga began to read his play.
The big hitting Frenchman dropped just six more games as he won the next two sets 1-6 6-3 6-2 6-4 to set up a second round clash with Cedrik-Marcel Stebe.
The German has an easier route into the second round as he was 6-3 2-0 up when Joao Souza returned.
Juan Martin Del potro also had to battle in his opening round against Albert Montanes and needed four sets to win.
After letting a 5-1 lead in the second set tie break slip away the former U.S. Open champion and ninth seed needed treatment on his left knee.
Del Potro started the match with the knee strapped but the trainer was called on court to give some further treatment.
And while the Argentine did look a little uncomfortable throughout the rest of the match he came through 6-2 6-7 (5-7) 6-2 6-1.
He will face Edouard Roger-Vasselin in the second round as the Frenchman saw off Vasek Pospisil 3-6 6-3 6-2 6-2.
The opening day was a good one for Spain as Fernando Verdasco book his place in the second round with 6-3 6-2 7-6 (7-4) win over Steve Darcis.
And former world number one Juan Carlos Ferrero rolled back the years with a very comfortable 6-1 6-4 6-3 win over Jonathan Dasnieres De Veigy.
