I thought it was interesting, so you should to.

Basically the article is talking about http://www.hittrackeronline.com/ a site that tracks home runs, and what players/teams hit a lot of balls that barely cleared the fences. The Giants were the top team on the list, percentage-wise.
Good news: Aaron Rowand didn't hit many "cheap" home runs (6 of 27). Maybe he maintains more of his power than we expect this year.
Bad news: Most of Randy Winn's (10 of 14) were of the "cheap" variety. I already wasn't excited about his years 34 and 35.
