News: Stammen agreed to a one-year, $2.25 million deal with the Nationals on Thursday, Jon Heyman of CBS Sports reports.
Impact: Stammen struggled in 2014 compared to his three previous seasons, but finished with decent numbers (3.84 ERA, 1.27 WHIP). He figures to continue in a middle-relief role for the Nats, with the ability to go multiple innings if needed.

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.
