Top seed Carlos Alcaraz powered into the fourth round of the Miami Open with a 6-2, 6-4 win over French veteran Gael Monfils at Hard Rock Stadium on Monday. The 37-year-old Monfils was coping well with the power play of the talented Spaniard until he hurt his ankle in the fifth game. While Monfils carried on bravely, bringing out some wonderful defensive shots from Alcaraz, the world number two was too much for the Parisian. There were plenty of smiles, in between the occasional wince from Monfils, who enjoyed some entertaining rallies where Alcaraz could show his deftness of touch.
