Pay-and-play league insight here. I played the past few summers in the AZ Collegiate Wood Bat League. Even this summer, when I was mainly working out at the AZ Baseball Ranch all summer, I was still able to pitch a few innings this summer in the AZ Wood Bat League just to work on the stuff I learned at the Ranch. As much as I loved playing in this league over the years, I am sure this is the direct opposite end of leagues such as the Cape...
Pretty much the AZCWBL is as pay-and-play as you can get. 6 week long season, games 5 days a week Monday-Friday. 7 inning games. Games played primarily at the local Phoenix area spring training complexes, and local junior colleges. In the years past the out-of-state kids stayed at the dorms at ASU, but the housing option wasn't available this year. Few D1 kids, but mainly kids from smaller schools or local junior colleges. Usually there's one team that stacks all the talented players in the pool and just dominate the league (that's the team with the most D1 kids, etc.)
Environment wise, it's very much laid back. At times players would show up as close to 15 minutes before the game started, and just "show and go." Coaches are pretty laid back for the most part, they're just there to write lineups, and that's pretty much it. Teams don't carry that much pitchers to ensure pitchers get innings, but a lot of times position players help out with pitching too since sometimes there's not enough. It truly is up to the player to push himself to get the most out of playing here. You will get your reps in for sure, but you're mainly on your own. Coaches mainly there to facilitate, not so much coach. A lot of the time it is kind of like little league, where everyone will get to bat (like 1-12) and you can switch in and out of your position whenever you want (trade every other inning at shortstop, etc.).
Recommend this league to anyone that feels the need to get consistent reps. Anyone can play if they pay the league fee of $500. Even unsigned college players, or incoming college freshman, or recent HS grads with nowhere else to play.
Hopefully one day I too can get into a prestigious summer league, as that is one of my three primary baseball goals at this time. I almost went to play for the SF Seals this summer (they're an independent college travel-intensive summer team that plays against teams in the West Coast League, Pacific International League, California League, etc.), but decided a spending the summer training at AZ Baseball Ranch would be much more beneficial for me, which it has been.
