Derek Jeter's home finale Thursday night was the most-viewed Yankees game in the YES Network's 13-season history, averaging 1.25 million viewers and reaching a peak of 1.99 million from 10:15 to 10:30 p.m.
The previous high was for an April 3, 2005, game against the Red Sox that averaged 1.21 million viewers.
Thursday's game, in which Jeter singled to drive in the winning run in the ninth inning against the Orioles, averaged 10.8 percent of homes in the New York area.
That night's Giants-Redskins game averaged 1.44 million viewers and 14.1 percent of homes in New York on CBS and the NFL Network combined.
On nights such as Thursday, ratings data does not fully reflect the reality that most area sports fans presumably were flipping back and forth between the two big events.
