News: Stammen was tendered a contract prior to Tuesday's deadline.
Impact: The normally reliable long man struggled at times in 2014 and saw a big dip in his K/9 rate, but Stammen will return and supply a middle-inning bridge to Tyler Clippard, Matt Thornton and Drew Storen.

News: Stammen gave up five runs on six hits without recording an out in the second game of Friday's doubleheader.
Impact: Ouch. The outing sent his ERA soaring from 3.22 to 3.84 and put a capper on a disappointing season that saw his strikeout rate fall from last year's 8.71 K/9 to 6.94 in 2014.
