meetings compared to the number of games they play against divisional and league rivals. For fans who support both teams, the Baltimore-Washington metropolitan area constitutes a two-team market in which they root for one team in each league; to such fans, the Beltway Series is a matter of interest because it involves both of their "home" teams, rather than their home team playing against a disliked crosstown rival. The Beltway Series tends to draw well in both cities, but this does not necessarily indicate that fans are attending to watch a chapter in a true rivalry between teams with a history of meaningful competition or animosity; many appear to view the series merely as an annual opportunity for low-key, good-natured competition between the teams and their fans for "bragging rights" in the Baltimore-Washington region. Players' attitudes With the exception of a September 2015 game at Nationals Park in which Nationals pitcher Jonathan Papelbon hit Orioles infielder Manny Machado with a pitch, resulting in an exchange of words between Machado and Papelbon, both dugouts emptying, and Papelbon's ejection from the game, no particular ill feeling has existed on the field between the teams. Players of both teams appear to view the teams in their own divisions – which they play 19 times each per season – as their rivals, and they attach no particular significance to the comparatively short annual Beltway Series, which merely pits them briefly against a team in a different league that they otherwise would not play unless they met in the World Series. Television broadcast concepts The Mid-Atlantic Sports Network (MASN), which owns the rights to broadcast both Orioles and Nationals games, televised the 2006 and 2007 Beltway Series in a conventional format, with each team's broadcasters covering the game for separate audiences via separate telecasts. From 2008 through 2013, however, MASN televised the Beltway Series using an unconventional concept in which mixed Orioles-Nationals broadcast booths covered each game. In the mixed-booth concept, the two teams′ play-by-play announcers – Jim Hunter for the Orioles and Bob Carpenter for the Nationals – alternated on play-by-play during each game and color analysts and sideline reporters from both teams worked together in the booth and on the field throughout each game. The concept was based on the premise that the Orioles and Nationals were both "home" teams for the combined Baltimore-Washington area, and that fans in both cities followed and
