"I do not see how Hague proved he has any more power"
1. His season high is 15, so he has hit 7+ in around 55+ Abs shows a hugh jump.
2. Its been written more than once that he has been working on adding more loft to his swing and also being more aggressive.
3. The ones i have heard on the radio were no doubters (though its only maybe 3 of his total)
So not only do we have hard results (7+ HRs) , but a strong cause effect correlation (chang in swing/approach first time weve seen these kind of results), and some (albeit little) first hand evidence.
The only argument against it is, maybe some were wind aided.
Like i said he might not hit 1 single major league HR, but there is no doubt he is showing much, much, much more power than he has at any time in his career. Considering that was his only major weakness coming through the system, there is no reason for his stock to rise. He has proven that the power (tool) is there (show me 1 person who hit 7 HR in 55 Abs that you would say doesnt have raw power) wheather he can effectively use it (in games that matter) is a whole different argument.
