Alex Sanchez is a good option as a 4th OF/utility guy. He was sick to start off the year, and that's why Inge was playing the OF, but when Sanchez is healthy, he's good. He is every bit as good as Pierre IMO, except he'll have a lower BA, but not by much. I was saying all pre-season how Sanchez is under-rated, and Pierre is over-rated. They're basically the same player.
Keep him until Preston Wilson comes back. And start Burrell, Griffey, Chipper, and Sanchez. If Jenkins gets hot you can sub him in for Sanchez, but he'll probably be injured before he goes on a hot streak.
