He only has one career save under his belt, but the Washington Nationals will open the season with Blake Treinen as their closer.

Dusty Baker named Treinen, 28, his ninth-inning man on Thursday.

Treinen competed with Shawn Kelley and Koda Glover for the job this spring after Mark Melancon signed with the San Francisco Giants as a free agent.

"I think a lot of us came into spring willing to put our heads down and compete and be the best that we can, knowing that we're all going to have valuable innings," Treinen said. "To be in the position Dusty has put me in, I feel honored. I'm excited to have that opportunity. I'm looking forward to progressing and taking it this season and doing the best I can for my teammates and hopefully locking down games for us."
