Andrew Friedman has often said bullpens are "volatile."
The Rays have been able to successfully tweak its stock of relievers each of the past several seasons.
Tampa Bay had a Major League-best 2.88 bullpen ERA in 2012, something that will be hard to repeat.
"So many things have to go exactly right," Jim Hickey said. "If I told you right now, [Fernando] Rodney was going to save 43 out of 49 games and have a 1.89 ERA, and that would be almost a disappointment compared to last year. They really did set the bar high.
"But I expect them to be very good, I expect them to be playoff-caliber good, and if we get into the playoffs, to take us all the way."
Friedman said they're still looking for one or two relievers, and he has a track record of acquiring quality arms for the bullpen.
