season until a multi-year agreement was reached between the Nationals and WJFK before the 2011 season. WFED remains on the network as an affiliate; its 50 kilowatt clear-channel signal allows the Nationals' home-team call to be heard up and down the East Coast. WWZZ (104.1 FM), which carried games in the 2005 season, was the team's first flagship radio station. Mid-Atlantic Sports Network (MASN) televises all games not picked up by one of MLB's national television partners. Bob Carpenter has been the TV play-by-play announcer since 2006 and F.P. Santangelo was hired in January 2011 as color analyst. Mel Proctor was the TV play-by-announcer in 2005, and former color analysts are Ron Darling (2005), Tom Paciorek (2006), Don Sutton (2007–2008), and Rob Dibble, who took over the job in 2009 and was fired in September 2010 after criticizing Stephen Strasburg for not pitching while injured. Ray Knight filled in as color analyst in September 2010 after Dibble was fired. Previously, WDCA (channel 20) carried 76 games in the 2005 season while the newly founded MASN was still negotiating cable carriage. From 2009 through 2017, MASN syndicated a package of 20 games for simulcast on an over-the-air television station in Washington. Broadcast partners under this arrangement were WDCW (channel 50) from 2009 through 2012 and CBS affiliate WUSA (channel 9) from 2013 through 2017. MASN did not continue the syndication deal for the 2018 season. In the midst of a season in which they finished with the worst record in Major League Baseball, the Nationals' television ratings were among the worst in the National League in July 2008 but increased during the 2010 and 2011 seasons. Since 2012, when they began to achieve consistent success on the field, their television viewership has grown continually and dramatically. By 2016, the Nationals′ prime-time television ratings were 15th highest among the 29 U.S. MLB teams, and they rose to 12th in 2017. Ratings declined to 18th among the 29 U.S. teams for the 2018 season.
