It looks to me like Cespedes just wanted to dive into the stands. He wasn't even close to catching this foul ball.
He did manage to take out some fans and any time fans are involved I'm happy. It's not that I want fans to get injured, although that is always a bonus, I just know the MLB will waste a ton of time trying to figure out how to prevent it.
It's just a matter if time before fans will be required to watch games in a bubble.
