Tallon Griekspoor broke his personal record for aces in a single match, recording 34 on Tuesday. The 30-year-old Dutch player reached the figure during his first-round match at an ATP tournament in Brussels. An ace is a serve the opponent cannot return, making the total a direct measure of his serving strength and accuracy. The performance surpassed the best aces haul he had previously achieved in any one match. The report did not identify his opponent, the final score or the number of games played. It also did not state how many serving opportunities he had, so the frequency of the aces within the match remains unknown.
