Carlos Alcaraz avoided a potential upset against Tomas Martin Etcheverry to book his place in the quarter-finals at the Monte-Carlo Masters.

The world number one triumphed 6-1 4-6 6-3 in two hours and 24 minutes to set up a last-eight clash with Alexander Bublik in Monaco.

After cruising through the first set, breaking Etcheverry's serve three times, Alcaraz found himself 4-1 down in the second.

The Spaniard had the opportunity to bring the second set back on serve, but squandered a break point opportunity at 5-3 down before Etcheverry forced a decider.

Alcaraz found his rhythm again, though, breaking Etcheverry in a long second game on his way to a 3-0 lead.

The 22-year-old then saved a break point to go 5-2 in the decider and clinched victory with his third match point.

Data Debrief: Alcaraz enjoying return to clay

Since the format's introduction in 1990, Alcaraz (35) is now one of six players to reach 20 Masters 1000 quarter-finals in fewer than 40 main draws after Stefan Edberg (26), Rafael Nadal (32), Pete Sampras (33), Novak Djokovic (34) and Jannik Sinner (39).

Alcaraz (84.7%, 105-19) now only trails two players in the Open Era (minimum 25 matches) for winning percentage on clay at ATP level: Nadal and Bjorn Borg.
