The TV audience for Tuesday night's division-clinching victory was almost twice as large as normal for an Orioles game on MASN this season, according to figures provided by the channel.
O's games averaged a 5.9 household rating this season, which means 5.9 percent of cable TV homes in the Baltimore market watched the games throughout the season. But Tuesday night the percentage of cable TV homes in the Baltimore market tuned to the game was 11.6 percent.
That translates to 127,000 homes and 179,000 viewers.
The peak came between 10 and 10:15 p.m. at the end of the game when the rating reached an 18.5 in households.
The ratings for the full game telecast and the top quarter-hour were the largest MASN had ever earned for an O's telecast not simulcast on WJZ-TV (Channel 13), the CBS-owned station in Baltimore.
John J. McGuinness, a MASN senior vice president, said the channel went out of its way late in the game and during post-game celebrations to capture the pictures and sounds without intrusions.
"We intentionally went commercial free," McGuinness wrote in an email response to The Sun. "We didn't want our fans to miss a second of this wonderful celebration. They earned it - they deserve it - Let's Go O's!"
