Video - The Hawk-Eye's Precise Call That Made Alcaraz and Ruud React

A few millimeters were enough to create a memorable moment: Alcaraz and Ruud humorously reacted to a ball called by the Hawk-Eye before leading Team Europe to a crucial victory.

In or out? The Hawk-Eye made an exceptionally precise call during the doubles match between the pairs Alcaraz/Ruud and Michelsen/Opelka at the Laver Cup.

At 5-5 in the first set, a serve from Michelsen barely nicked the line by mere millimeters, as shown by the Hawk-Eye. Alcaraz and Ruud then rushed to the screen at the back of the court to humorously express their surprise.

The two men calmly finished their match (7-6, 6-1) to revive Europe's hopes on the final day of the competition.
