Dice-K was a big pitching acquisition by the Red Sox several years ago (not sure of the year but it could have been 2006) and he was a big part of the reason they won the World Series in 2007. He was a solid pitcher in Japan before he came to the USA and had some great years with the Red Sox but IIRC, he has had a few years of injury lately and I think that's how the Mets ended up with him.
