Fast National ratings for Sunday, October 17, 2010.
 
A National League Championship Series game between the Phillies and Giants on FOX went head-to-head with the Colts and Redskins game on NBC's Sunday Night Football. Not surprisingly, it turned out that in the battle between mid-postseason baseball and regular season football, there was no competition at all.
 
Among adults 18-49, NBC averaged a 5.4 rating for the night, easily winning the key demographic. FOX was second with a 3.3 rating, though much of that came from early-evening NFL overrun, rather than baseball. CBS was a close third with a 3.0 rating, with ABC's 2.6 rating good for fourth.
 
Overall, NBC averaged an estimated 14.25 million viewers to go with an 8.8 rating/14 share. CBS was second with a 7.2/12 and 11.87 million viewers. FOX's 6.1/10 and 9.84 million viewers took third, beating ABC's 5.8/9 and 9.265 million viewers.
