Don't know who you have to drop, but in general, yes he's worth a pickup. Cameron will put up good HR and SB numbers while he's healthy. He always gets knocked for being injured, and that's fair, but he rarely get credit for being a good power speed option. Look at what he does in limitted action, if you can absorb a low BA he's very attractive. Also, he's had a lot of periods of depressed statistics because he was playing through injuries. He dealt with bad wheels his entire 2004 campaign. Not saying he's going to be injury free, but in healthy periods, he is a real asset. Also, about the Petco effect, Safeco and Shea are not hitters havens.
