As Friday's 4 p.m. ET non-waiver Trade Deadline approaches, the Nationals are looking to improve their bullpen. Outside of Drew Storen, the team's current closer, the 'pen has been shaky. Storen moves into a setup role, a job he did well last year before reclaiming his closer's role in September.
Washington thought it had found an eighth-inning option in David Carpenter, but he is on the disabled list because of shoulder issues. Aaron Barrett and Blake Treinen have been inconsistent, and Treinen was recently sent back to Triple-A Syracuse because he couldn't finish off hitters.
