First I've seen the rumor, but I'm not throwing stuff around the room, yet. It wouldn't be historically bad in any way, as Garciaparra can hit, and its easier to find a quality right fielder. Personally, I think the trade is unnecessary more than anything. I stand by my position that Abreu is hugely under-appreciated.
I'd like to go back to the Dan Plesac retirement for a moment. Few people will make a HOF case for Plesac, and I wouldn't vote him in myself. Still, most people don't realize how good Plesac was. His K/9 IP rate is better than any other reliever in baseball history, and 8th best of all time. Plesac struck out batters more frequently than Roger Clemens. In any case, Plesac gave the Phillies a heck of a final season. Enjoy your retirement.
