Norwegian startup Muybridge has rocked pro tennis. Next up: soccer, hockey, F1. . . and even emergency medicine. Several times during the men’s final of the Madrid Open tennis tournament between Casper Ruud and Jack Draper last spring, TV viewers were treated to a remarkable camera perspective. They watched the match from just behind the baseline, effortlessly following the player’s movement step for step and glimpsing his perfect angle on the ball with every shot.
