This was even worse. Mookie Betts(LA RF) made an incredible catch literally on top of the wall all the way down the first base line. It would have been a foul ball if untouched. The fan grabbed his glove opened it and took the ball out. Then threw it back into the field.
He had a helper too. I believe they were both ejected from the game. They should be banned by major league baseball for fan interference.
