""Didn't change his swing. Changed his set-up . Big difference. :)""
Take it up with Sanserino, he wrote the article. I don't disagree with you, but Sanserino's the one who said Hague "tweaked" his swing. I can buy that the article could have been better-written, from a pure baseball perrspective. But, the point is, when people say Hague made a change to try to generate more power, they're getting it from that PPG article, plus this one:

Plus other articles.
I think that due to it being reported that Hague made adjustments, both physically and mentally, to try to generate more power, is why they're trying to read more into Hague's ST HR barrage, than they would anyone else having a hot March. If Hague really can hit a few more over the fence, while not losing anything off his average, or his plate discipline, then the Pirates might have lucked into a 1B solution.
We already know Hague can put up a .360+ OBP. If he can also drive the ball enough to put up a high-.400 SLG, then you've got an .840 OPS guy at 1B. And only 8 teams had one of those in MLB, last year. And only 11 of them had one, in 2010.
