Janssen has a 4.50 ERA and 5:2 K:BB ratio through six innings this spring.

Analysis:

His role in the Nationals' bullpen isn't entirely clear yet, but given Janssen's late inning experience he will likely open the season as part of Drew Storen's set-up crew, and he could be first in line to get a crack at the closer job if Storen struggles. His lack of big strikeout numbers severely limits his fantasy value if he isn't getting saves, however.
