Since SNY went on the air in 2006, Mets viewership has nearly always lagged behind the audiences amassed by the Yankees on YES. This is hardly a revelation: In nearly all of those seasons, the Mets performed poorly while the Yankees won a World Series championship in 2009 and were always at least pretty good.

In 2013, Yankees viewership was double that of the Mets. Last year, it was nearly double.

But with the Mets on an 11-game winning streak and the Yankees at 9-7 entering Friday, the chasm in their television audiences has narrowed significantly.

Through Tuesday, Mets games this season on SNY were drawing an average of 253,339 viewers for each game, up by 47 percent from the same time last season. At YES, Yankees viewership had tumbled by 21 percent, to 267,000.
