Fast National ratings for Tuesday, June 10, 2014.

The San Antonio Spurs routed the Miami Heat on Tuesday night, leading ABC to comfortable wins among young viewers. However, the NBA Finals Game 3 was down from Sunday's Game 2 and lost to "America's Got Talent" overall head-to-head, though ABC still scored a narrow nightly win in total viewers.

Even against the NBA Finals, NBC's summer success "The Night Shift" maintained its key demo numbers, while The CW's "Famous in 12" also stayed steady in its second week. 

Both FOX's "Riot" and "I Wanna Marry 'Harry'" were flat with their dismal key demo numbers, but while "Riot" added a couple viewers, the royal dating dud dipped below a million viewers. [I'd bet on "Harry" ticking above a million in Final Live + SD numbers, but for now, those are ugly numbers.]

Among adults 18-49, ABC averaged a 4.0 rating for Tuesday night, nearly doubling the 2.2 rating for NBC in the key demographic. CBS was a distant third with a 0.8 key demo rating, followed by FOX's 0.4 key demo rating and the 0.3 key demo rating for The CW.
