Hargrove resigns despite M's Success

Hargrove had a press conference today before the game announcing he would resign as manager after the game. The M's went on to win in the bottom of the 9th for their 8th in a row to get them to 12 over.
I was never a big fan of Hargrove, but now that were winning, I'm fine with him. His bullpen management has been a total turnaround from last year, and he's using Broussard correctly finally. He still misuses young people, such as not using O'Flaherty in tighter situations, and using Morrow in tight situations, and I wonder what he'd do if we called up Adam Jones. However he is doing a good enough job otherwise. He even put Vidro into the bottom third of the lineup for a while.
Anyways, something tells me something bigger is going on. Several have speculated that he was "let go" to resign Ichiro, and others have speculated that his wife or family member has some sort of illness. Whatever the case is, I hope this doesn't disturb the team chemistry, and I wish the team well.
