“The Masked Singer” fans got a double shot on Wednesday night, as Fox had to hold an episode last week to accommodate Game 7 of the World Series. It worked out quite well, as Fox doubled the ratings for its closest competition, NBC, last night in the key 18-49 demographic.

NBC finished first in total-viewer averages by 300,000 viewers, however.

Fox was first in ratings with a 2.0 rating/9 share in the advertiser-coveted 18-49 demographic and second in total viewers with an average of 7.1 million, according to preliminary numbers. The first episode of “The Masked Singer” at 8 p.m. posted a 2.0/9 and 7 million viewers. At 9, the second episode maintained 100% of that rating and share and grew its overall audience to 7.2 million viewers.
