That suggests that teams should not be making roster decisions based on spring training performance, which in turn suggests that spring training games are a waste of time except as a way to get players game ready--and they probably don't need 30 games to do that.

Teams shouldn't abandon their preseason plans based on spring training performance. If there's a close battle for a job, especially involving minor leaguers the manager hasn't seen before, it's not a terrible idea to consider the spring results. But I agree that more games are played than there is really a need for.

Spring training is like practice or exhibition. Why would anyone care what the stats are. Unless you think David McCarty's race for 50 homers is on.
