I think Pineda is heading into the "people are afraid of overrating him so he is becoming underrated" zone. Let's not forget that he was one of the best pitchers in the league in the first half of last season. He may take a little while to get adjusted to the Big Apple, but I think he could be the next great Yankees pitcher.
Your infield is super solid - something I messed up in one of my own drafts. OFers will surface on waivers throughout the season, and I think Werth is in line for a good year on a sneaky good Nats team.
And don't worry about closers--just make sure you keep tabs on the waiver wire. There will be guys to pick up.
