Bernardo Fallas did something similar yesterday, and the Biz of Baseball comes through on an in-depth breakdown of Wandy's arbitration case (which was, apparently, professional).
I won't pull too much, because it is completely worth a thorough read, but:
Salary arbitration is tricky to predict given the “selling the deal” aspect by the sides presenting. But, based on Rodriguez spike in July, his asking salary, and the Astros recent history in salary arbitration hearings, we’re going to side with the Astros winning the case.
