With Max Muncy at the plate for the Dodgers with the bases loaded and one out, he drove a 92 mph cutter to straight away center field. Sal Frelick made a leaping attempt to rob the would-be grand slam. And he did just enough, making contact with the ball and then catching it off the bounce from the wall.
