I want to get a better 2nd baseman who should I trade to get Pedroia?

Any pitcher will tell you that there is nothing more dangerous to him than a good hitter who is overdue. Yesterday Braun went from .222 to .300 in one day. It's way too early to dump a good stick like Uggla. He is tied for third for 2B in RBI's. Pedroia will give you a better BA and more SB's but Uggla will give you twice the power and more RBI's. He will bounce back. It would be a shame for you to have him until he gets good and another team reaps the benefits. Be patient. He is good.
