Valentin Vacherot defeated Hubert Hurkacz 6–7, 6–3, 6–4 in the second round of the ATP Monte Carlo Masters on clay on 9 April 2026, confirming his status as pre-match favourite with odds of 1.63 to Hurkacz's 2.23. The match remained competitive through a tight opening set that went to a tiebreak, which Vacherot edged, before the Frenchman asserted control in the second and third sets to secure passage to the quarter-finals. Vacherot's progression represents a solid performance on the principality's slow courts and maintains his momentum in the Masters 1000 calendar.
