Denis Shapovalov's first career Grand Slam as a seeded player didn't last long.
The No. 24 seed, from Richmond Hill, Ontario lost 5-7, 7-6 (4), 7-5, 6-4 to world No. 70 Maximilian Marterer of Germany in the second round of the French Open on Thursday.
In a battle of two players making their French Open main draw debuts, Shapovalov, 19, had more double-faults than aces and far more unforced errors than winners.
Shapovalov, 19, became the 10th men's seed to be eliminated at the tournament.
