PROBLEM: Review: This is my sixth edition, and this book is still a great way to get ready for the season.But the writing has taken a distinct turn toward the serious. The essays and player profiles are still chock full of relevant numbers and piercingly well-considered arguments, but this year they are also somewhat...I really don't want to say it...tedious.What was once a light-hearted romp through some serious baseball thinking is now rather dense and dry. I'll buy again next year, but I hope somebody sends them a keg of Lighten-Up.+ 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: I ordered a 3X, because that's the size that the website said to order, it came and lacked about 8 inches closing....so I looked at the package and it says I should have ordered a 5x...seemed extreme, but I exchanged it.I was very impressed with the speed of the exchange, I'll say that....However, when the 5X arrived, it's so big it just gaps and falls off? So, was the 3X mislabeled, or is this 5x mislabeled? I'm needing something with some firm support for post surgery care....so I really don't know what to do at this point? 
 Polarity: Negative

SOLUTION:
True
