Wednesday night belonged to “Big Brother,” with the CBS reality stalwart matching last week’s premiere rating of 1.8 in the adults 18-49 demographic, drawing 6 million watchers opposite NBC’s continued coverage of the Olympic swimming trials, which earned a 1.2 demo score and 5.7 million viewers at 8 p.m. Fox’s “MasterChef” earned a 1.1 rating and 3.9 million viewers, while ABC and The CW aired repeats all night.

At 9 p.m., CBS still eked out a 0.9 demo score with a repeat of “Criminal Minds,” with the second episode of “American Gothic” matching last week’s modest premiere rating of 0.7 at 10 p.m., earning 3.5 million viewers. Both went up against a double bill of NBC’s “The Night Shift,” which scored a 0.8 in the demo, beating both shows with 4.5 million viewers. “Wayward Pines” matched “Night Shift” with a 0.8 in the demo at 9 p.m., up a tenth from its most recent outing.

CBS won the night overall in the adults 18-49 demo, earning a 1.1 versus Fox’s 1.0, NBC’s 0.9, ABC’s 0.8 and CW’s 0.2, but NBC beat the Eye in total viewers, scoring 4.9 million overall against CBS’ 4.6 million, Fox’s 3.14 million, ABC’s 3.13 and CW’s 0.8 million.
