The Giants may have discussed trading for Corey Hart with Jonathon Sanchez the potential return...
Sanchez would be a nice pitcher to add. His 2008 FIP was 3.85 based on a really nice strikeout rate: 8.94 K/9.
Moving Hart would be more problematic than moving Fielder in terms of there being no obvious in house replacement in the outfield. Gwynn - Kendall - Pitcher seems like a great time to go and grab a beer.
