Rising star Carlos Alcaraz saved a match point in the fourth set and erased an early deficit in the fifth to overcome Albert Ramos-Vinolas 6-1, 6-7 (7), 7-5, 6-7 (2), 6-4 at Roland Garros.
The sixth-seeded Alcaraz grabbed six of the final seven games, and the last half-dozen points, to finish off the second-round victory that lasted more than 4 1/2 hours.
Alcaraz is just 19 but arrived in Paris with a lot of expectations — of his own and of others — based on his breakthrough season that includes a tour-leading four titles. He is the youngest player to break into the top 10 of the ATP rankings since Rafael Nadal in 2005.
En route to the Madrid Open title on red clay earlier this month, Alcaraz became the first man to beat both Nadal and Novak Djokovic in the same tournament on that surface.
But he was quite close to making a quicker-than-anyone-expected exit against fellow Spaniard Ramos-Vinolas, a 34-year-old who is ranked 44th.
Alcaraz was a point from losing while Ramos-Vinolas served for the victory at 5-4 in the fourth set. But Ramos-Vinolas missed a forehand there. Eighty minutes later, after trailing 3-0 in the fifth, Alcaraz earned his first match point and converted it with an ace.
