hide rows automatically based on a value in that row

I posted this a few days ago, but I might have put it in the wrong place or something. Anyway, here is my issue:

I have a spreadsheet we use to track the averages and rating of players in a league we manage. The spreadsheet has two tabs. The first computes the average each week, and the other tab takes data from the first to build a book we print weekly. To be in the book you need to have played at least 32 games. What I would like the second tab to do is to hide any row where the player has less than 32 games for me automatically. I know I can do it manually, but it seems we often miss one and have to reprint the book. Below is the spreadsheet i'm using.

Thanks for your help!
