To me the real test of home run power is when there are men on base. Not because of some mythic clutch ability, but because pitchers adopt different strategy when the long ball could really hurt them. Solo home runs are fine and all, but they happen because the pitcher was willing to risk it; I think it's a large explanation for what we saw with Plouffe last year when his BA was quite low but he suddenly went beserk with the dingers. For that reason, I'm not overly excited by the current surge. I've got an open mind though.
