The Washington Nationals have inquired on both star free-agent closers — Wade Davis and Greg Holland — and are said to like both. There hasn’t been much activity among the top free agents, but things could be looking up for Davis and Holland, who stand apart from the crowd. The Nationals are said to like both pitchers very much. They tried to get Holland last year, and one source suggested that GM Mike Rizzo badly wanted to sign him to solve their closing issue. Washington finally improved its ninth-inning concerns by acquiring Sean Doolittle in a summer trade with the Oakland Athletics, and they also have Ryan Madson, who came in that trade, plus Brandon Kintzler, who was brought back. However, pitching has been a hallmark of Rizzo’s teams in Washington, and they are continuing to consider the better options on the market.
