Without a doubt this is a busy part of the fastpitch softball summer season. Tournaments every weekend, for some teams league or scrimmage doubleheaders during the week, and maybe a practice squeezed in here or there.
What that means is very little time to work on individual skills. Some may be able to handle that, but they're in the minority. For most, all this play time means skills are actually deteriorating.
It makes sense. In a practice setting, a hitter might take 100 to 200 swings in a session. In a game, she's lucky if she gets 12. That's a pretty big delta.Same with fielders. Whereas in a good practice session you may field 50-100 balls or more, you may go a game or two without any significant fielding chances — especially if your team has dominant pitching. Sure, you get some practice during warm-ups, but your focus is different then. It's on getting ready for this game coming up, not on necessarily improving your skills.
Even pitchers can have it tough. Sure, you're still throwing a lot of pitches. But the focus will be on the ones that are working. The pressure is on to throw strikes and keep baserunners off the bases, so if you curve is working and your rise is not, the rise isn't going to get much of a workout.
That's why it's important to make time for that sort of deep practice that will keep skills sharp and you playing the way you want to play. Which probably means you'll have to get out on your own to do it.
