We went to a clay type infield mix a couple of years ago because we were looseing so much of it from wash. This mix hardens and when it rains it runs off without any standing water or run off of mix. What you have to do is wet is some before you play or practice to get it at the right playing condition. This is a great surface to play on if you have irrigation in order to wet it. It dries quickly and we have not had a rain out in two years.
