Evan Longoria and Geovanny Soto win Rookie-of-the-Year

Unsurprisingly, Evan Longoria of the Tampa Bay Rays and Geovanny Soto of the Chicago Cubs won the 2008 Rookie-of-the-Year awards hands down.

The thing I want to know is how Edinson Volquez , who is not even eligible for the award based on having too much prior Major League experience, managed to get votes! Sure, Volquez had a fantastic season. But he pitched too much in the Major Leagues before 2008 to be a rookie. I don't know if the writers in question think the specific rules should be changed or just didn't know that Volquez isn't actually a rookie. Shouldn't the votes for him get automatically nullified?
