There had to be some serious topspin on that, too. When it first hit the grass, it just took off. I'm not sure of the physics of everything with the wet grass. But, from that Fangraphs article looking at similarly hit balls, that data doesn't include spin. So I'm wondering if it has something to do with how quick Javy's hands are and if it had something to do with how fast the bat was, I guess, rotating or whatever as Javy's swing went through the ball.
