It wasn't that he was able to get to the ball, but that he was able to hang onto it given that he caught it with the palm of his glove and the momentum of his dive caused him to slap the glove face down into the ground.

After the game he checked the video just to be sure.
"I watched it," Ross said. "And I still don't know how I hung onto it."
