HAMBURG, Germany — Top-seeded Carlos Alcaraz recovered from a slow start to beat Filip Krajinovic 7-6 (4), 6-3 and reach the quarter-finals of the Hamburg European Open as Francisco Cerundolo stunned Andrey Rublev 6-4, 6-2.
Alcaraz saved four set points down 4-5 in the first set before surging back to beat Krajinovic and improve to 21-2 on clay this season.
