Every Monday, Sports World News will update you on all 30 closer situations in Major League Baseball. Every fantasy baseball owner knows that closers are the most fickle assets in the game, and league's can be won by snapping up the right guys in the right situation.

Conversely, owning a bullpen full of closer busts can be a nightmare. Stay prepared with our weekly guide on who is about to lose their job, and who will take their place. Each closer will be designated with one of three statuses-Locked down, Hot seat, or Grab the next guy. We begin in the American League West.
