What happens to the "scuffed balls" the catcher hands over to the umpire?

Most defective balls are kept in the home teams clubhouse and are then used in batting and fielding practice before games. Some of the better balls however, are used for souvenirs. Either way they are not wasted.

They can be given out but usually brand new balls are used for that. Most of the time the used balls in the game are paced in the teams practice bucket and used for practice.

I believe that they're used for batting and fielding practice. Many of those are then thrown to the fans who show up early to watch batting practice.

Some are given away to fans in other ways. I got one from a bartender here in Chicago at US Cellular field. The players give them to the bartenders in the picnic area here.

They become the property of the home team, because they furnished the new balls for the game. Then, they are used for practice.

They become batting practice balls used before future games.
