I think my pen is pretty strong to be honest. Sure its not one of the best in the league, though I never said it was. Boxberger and Kevin Siegrist have been fantastic for me there is no denying that. Grimm hasn't got many holds, though as we've seen with BP arms all they need is an opportunity. Grimm has posted a 13.68 K/9 so far this season, which is a reason to roster him. Jeffress has been pretty good and he's getting his share of holds. Also, a speculative play with him for some saves if K-Rod gets dealt. Barrett has been very good, outside of a couple of bad outings and is getting holds in the Nats bullpen. Vizcaino is a young guy and a couple of years ago was a highly touted pitching prospect - he has all the weapons and skill set to have success in the pen long term. I'm willing to roll the dice on him as he offers some nice potential and theres nothing to lose. Also, if Atlanta deals Johnson, I'm sure Vizcaino gets a first look in the 9th. I think its a solid pen that can be even better if someone like Jeffress or Vizcaino find themselves in a closers role. Like I said, I still would like add another closer before the deadline since my BP is thin on arms who can get me saves.
