Arthur Blockx secured a straight-set victory over 16th seed Federico Cerundolo at the Madrid ATP Masters 1000, winning 7-6(8), 6-2 in the round of 16. The Belgian player edged a tight opening set before pulling away decisively in the second.
Blockx will face Casper Ruud in the quarterfinals after maintaining his level while Cerundolo's performance declined. The match showcased Blockx's ability to convert pressure in the tiebreak and capitalize on his opponent's drop-off in the second set.
The quarterfinal matchup is scheduled for later in the week as the Madrid tournament progresses.
