Baseball players have a lot of down time, so a lot of them have started Live Journals.
Thanks to Daryl for compiling names and links. The important ones:
Arroyo, Bellhorn, Damon, Millar, Mirabelli, Varitek and Theo
A-Rod, Jeter, Matsui, Posada, R. Johnson, Sturtze and Bubba Crosby
Pedro and Mientkiewicz and Clemens and Nomar
Click on these and ... well, good luck getting any work done today.
