The Arizona Diamondbacks have called a press conference for 1:30 PM MST to announce a player personnel decision. No details were given, but since they are calling a press conference, I have to assume it's a fairly major decision. It will even be carried on FSN Arizona. More details as they emerge.

UPDATE

According to The Arizona Republic, the press conference is to report that the Diamondbacks and outfielder Eric Byrnes have reached agreement on a three-year extension worth in the neighborhood of $30 million.
