World number one Carlos Alcaraz came back from a set down to defeat Britain's Jack Draper in the opening round at the Swiss Indoors in Basel.
Alcaraz took his third match point on serve to edge an entertaining match.
He will play Dutchman Botic van de Zandschulp or France's Adrian Mannarino next.
Draper capped an impressive first set by breaking the US Open champion's serve for a second time, doing so to love, to move a set from victory.
However, Alcaraz responded with a double break early in the second set as the Spaniard opened a 4-0 lead on his way to levelling the contest.
