there are pitch counts for pitchers.
it gets players to get more focused for playing games right now and ideally make them more ready for the first week of April.
it can also open up a chance for a younger player to get more Spring Training action with your team if the normal position player is off playing for Team USA or whatever team. more games = more people playing.
injuries are a concern but as a fan, these are enjoyable games to watch. it's just extra baseball for me to watch. I'll never complain about that.
