Defending Miami Open champion Daniil Medvedev won his 350th career match to move into the quarterfinals for a fourth straight year, beating Dominik Koepfer 7-6 (5), 6-0 on Tuesday. Top-seeded Carlos Alcaraz also advanced with ease in a 6-3, 6-3 win over No. 23 seed Lorenzo Musetti. Alcaraz, who beat Musetti in less than 90 minutes and looked comfortable as ever on the court, said he's “probably” playing his best tennis since last summer.
