What the heck has happened?

It's July 1st. We're hitting the midway point of the baseball season, and the Arizona Diamondbacks officially hit the skids several weeks ago. The WHEELS have come off. How can a team that started the season by going 20-8 now be 42-41? What has happened to the offense? Why can't they hit the ball? What's happened to the bullpen? Why do they have such a hard time holding leads?

I at least take solace in the fact that after the All-Star break, the Diamondbacks will start playing divisional opponents again. At that point they can beat up on their own weak division, pad their record, and then start playing against the better teams again.

Go Diamondbacks. Quit blowing winnable games.
