World No. 3 Alexander Zverev outclassed Federico Delbonis 6-1, 7-5 in Monte Carlo on Wednesday to reach the last 16 of the Masters tournament after top seeds Carlos Alcaraz and Felix-Auger Aliassime crashed out.
Zverev, who took to court as the highest ranked player remaining in the tournament, lost the first four points of the match but breezed through the first set in just over 20 minutes and dropped only three points on serve.
The 24-year-old was tested by Delbonis in the second, fighting back from 2-4 down and winning the next 11 points to move within a game of victory before converting his third match point.
