One of the key factors in the Baltimore Orioles' surprise turnaround last season was their incredibly solid and shutdown bullpen.
The team had five relievers with over 50 innings pitched and ERA's at 2.64 or under, making for a smooth transition from taking the starting pitcher out with a lead to shutting the door on the opposition with first-year closer Jim Johnson.
Most of the relief corps will return to pitch for the team in 2013, and barring anything unforeseen, will again come together and attempt to replicate their success.
With that in mind, let's take a look at these pitchers and rank them in the order of which arm is most trustworthy to hand the ball to in a tight situation. Since there remains a spot or two open and up for grabs headed into spring training, I'll only be covering who can be considered a lock for the 'pen when the team heads to Tampa for Opening Day.
