The Yanks signed a centerfielder today: Bernie Williams. (Johnny’s deal is still pending). Bernie returns for one more go-around and $1.5 million. This signing will keep the fans happy (including this one), though many a sabermetrician is less than pleased to see old 51 eating up a roster spot. Anoither take: the Yankees keep their hero, and steal Boston’s too. Call it an early Christmas. And the trains are going back on line to boot. Hurrah.
