MASN's Mark Zuckerman writes that the back end of the Washington Nationals bullpen is going to be a problem the rest of the year after they shipped closer Kyle Finnegan and relievers Andrew Chafin and Luis Garcia away at this week's trade deadline. Zuckerman mentions Jose A. Ferrer as the potential favorite for saves now, at least against lefty-heavy lineups. But against righties late in games, the team could go with Cole Henry or Zach Brzykcy. Ferrer is probably the first target in deep fantasy leagues off the waiver wire if you're desperate for saves, but as Zuckerman notes, an already shaky bullpen just got worse with two months left in the season. Ferrer is a 25-year-old southpaw gets a lot of whiff on his changeup, but he's struggled to a 4.78 ERA and 1.22 WHIP with a weak 20.1% strikeout rate in 52 2/3 frames this year.
