Treinen will be in the mix for the Nationals' closing job in spring training, The Washington Post reports.
Nats manager Dusty Baker may prefer to give the spot to someone with more experience, but Treinen improved his numbers against left-handed hitters in 2016 while also looking sharp in high-leverage situations, holding opponents to a tiny .128/.261/.154 line. The 28-year-old should have a prominent late-inning role whether he closes or not, though, making him a safer pick in fantasy formats that use saves plus holds as a category rather than just pure saves.
