Sixth seed Andrey Rublev came through a tough test against Taro Daniel to reach the second round of the French Open.
Russia's Rublev did not have it all his own way on Court Simonne-Mathieu but worked his way to a 6-2 6-7 (3-7) 6-3 7-5 win over Japan's Daniel.
The 26-year-old is looking to go beyond the quarter-finals of a Grand Slam for the first time.
World number three Carlos Alcaraz and Britain's Andy Murray are also in action on day one in Paris.
Rublev has struggled with his on-court demeanour over the years and threw his racquet to the ground in frustration after missing three set points in the second set.
