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.

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