Matteo Berrettini vs Adolfo Daniel Vallejo prediction

Matteo Berrettini hit back to sink Chengdu champion Alejandro Davidovich Fokina in Tokyo.

The Spaniard’s exertions appeared to catch up with him as the Italian roared back following a first-set breadstick to clinch a 1-6 7-6 6-4 victory.

Berrettini will now take on Adolfo Daniel Vallejo after the Paraguayan produced a huge shock to crush Rafael Jodar 6-1 6-3.

This will be a maiden meeting and there’s just nine places between the higher-ranked world number 47 Berrettini and the South American qualifier.

If you want to take a punt on the slight underdog, there’s very much scope there, particularly given the way he swept aside Jodar.
