Nationals acquire catcher Dan Butler

The Washington Nationals acquired catcher Dan Butler from the Boston Red Sox on Wednesday, in exchange for left-handed pitcher Danny Rosenbaum. President of Baseball Operations and General Manager Mike Rizzo made the announcement. Butler, 28, joins the Nationals after six seasons in the Red Sox organization. The right-handed hitting catcher appeared in seven Major League games for Boston in 2014, starting five behind the plate and going 4-for-19 (.211) - with three doubles. Over the course of six Minor League seasons, the reliable backstop is a career .256 hitter with a .349 on-base percentage and a .416 slugging percentage. In 2013, Butler caught 72 games for Triple-A Pawtucket of the International League and posted a .262 average with 14 home runs, 19 doubles and 45 RBI. Butler, who is considered a strong defensive catcher, was a two-time Mid-Season Minor League All-Star (2010, South Atlantic League; 2011, Carolina League) and a four-time Minor League Player of the Week. Rosenbaum was selected by Washington in the 22nd round of the 2009 First-Year Player Draft out of Xavier University in Cincinnati, OH. In six seasons in Washington's Minor League chain, Rosenbaum went 34-36 with a 3.12 ERA in 121 games (116 starts). He is currently rehabbing from May, 2014, Tommy John ligament reconstruction surgery. Butler will be added to the Nationals' 40-man roster, which is currently at 39.
