Hugo Gaston withdrew from Roland Garros on Tuesday due to abdominal pain. His scheduled second-round opponent, Ben Shelton, advances to the third round.
In the pair's first Lexus ATP Head2Head meeting, which came last year in the first round of Roland Garros, Shelton won in four sets. Gaston will not be able to level their series this tournament.
The Frenchman rallied from two sets to one down in the first round against countryman Ugo Blanchet to triumph in five sets. In his post-match press conference, he did not reference the abdominal pain.
Shelton, who ousted Lorenzo Sonego in his opener, will compete in the third round at the clay-court major for the second consecutive year and will try to make the fourth round on the Parisian clay for the first time. The 13th seed will take on 20th seed Stefanos Tsitsipas or Italian Matteo Gigante.
If Shelton advances, he will have reached at least the fourth round at all four Grand Slam tournaments. The lefty is a two-time major semi-finalist, including a trip to the last four of the Australian Open earlier this year.
