Fukudome is in a mini slump right now. 2-21 with 7 K's. 3 singles hitters at the top of the lineup is a little too much for me (at least Fukudome has been a singles hitter so far this year). That's really the main problem with Barney at the top-he's fine as a 2 hitter but it causes problems for setting the rest of the lineup. You want Castro up near the top and Fukudome is a natural top of the order hitter (plus you don't want to have Fukudome and Pena too close to each other in the order). The question is, if the hitters are so interchangeable, do you rely primarily on people being hot? If that was the case, Soriano, Soto, and Byrd would be moving up right now while Castro, Fukudome, and Ramirez would be moving down in the lineup. But I don't know if you want to make wild swings in the lineup based on a week or two of results especially when they could so quickly reverse.
