Booing Lo Duca

I was listening to the Washington vs Philadelphia game this evening. I only tuned in in the 7th inning. Anyway, Lo Duca came up as a pinch hitter in the 8th and the Phillie fans booed him. From what I could gather the Phillie fans have been booing him every time he batted. The Philadelphia announcers said Lo Duca had no idea why he was being booed, but he did offer possible explanations: (a) he was named in the Mitchell Report and (b) he played for the Mets.

I hope it's the latter because that's just so pathetic. Do Philadelphia fans boo every ex-Met?

MLB Audio went down in the bottom the 9th and I missed the Phillies' walk-off walk win.
