Fox’s “Wayward Pines” ended its season on a high Thursday, standing as the night’s — and most likely the week’s — top-rated scripted original in the key young-adults demo. Also of note on Thursday was another season high for ABC’s “Rookie Blue,” even while skedmates “The Astronaut Wives Club” and “Mistresses” slid.

According to preliminary national estimates from Nielsen, Fox’s “Wayward Pines” averaged a 1.2 rating/5 share in adults 18-49 and 3.9 million viewers overall in the 9 o’clock hour, matching its high in the demo. “Wayward” was already summer’s top-rated scripted program in adults 18-49 with a 1.92 rating in “live+3,” and its finale should also stand as the full week’s No. 1 scripted original in “live plus same-day.” There’s been no word regarding a possible second season of the M. Night Shyamalan drama starring Matt Dillon.

Elsewhere, CBS won Thursday behind “Big Brother” (1.8/7 in 18-49, 5.8 million viewers overall), which was down a little from last week but remained the night’s top show in 18-49. Repeats of “The Big Bang Theory” (1.5/7 in 18-49, 7.3 million viewers overall) and “Mom” (1.2/5 in 18-49, 5.7 million viewers overall) also won their timeslots, and 10 p.m. drama “Under the Dome” (1.0/4 in 18-49, 4.6 million viewers overall) edged up from its low of last week and tied for the English-language broadcast lead in its hour among adults 18-49.

At ABC, “The Astronaut Wives Club” (0.6/3 in 18-49, 3.8 million viewers overall) inexplicably fell 34% week to week (0.95 to 0.63) to its low, tying in the 8 o’clock hour with Fox’s “Boom” (0.6/3 in 18-49, 2.2 million viewers overall). It was followed by “Mistresses” (0.7/3 in 18-49, 2.9 million viewers overall), which also saw a surprising drop, falling 20% from last week’s summer-high score (from 0.86 to 0.69). Given those declines, the latest gain for 10 p.m. drama “Rookie Blue” (0.8/3 in 18-49, 3.8 million viewers overall) was especially impressive. After kicking off its sixth season with a series low 0.63 rating in 18-49, the Canadian cop drama has built with each week: 0.63, 0.66, 0.70, 0.74 and now a preliminary 0.79.

NBC’s “Food Fighters” (0.8/3 in 18-49, 3.5 million viewers overall) was down a tick from last week, and “Dateline” held steady (1.0/4 in 18-49, 5.2 million viewers overall), edging ahead of CBS’ “Under the Dome” for the broadcast lead at 10:30 p.m in both 18-49 (1.1/4) and 25-54 (1.6/5).

CW had another low-rated night of originals with “Beauty and the Beast” (0.2/1 in 18-49, 1.0 million viewers overall) and British import comedy “Dates,” which again managed a mere 0.1 in the demo and about 500,000 viewers overall.

Preliminary 18-49 averages for the night: CBS, 1.4/6; NBC and Fox, 0.9/4; Univision, 0.8/3; ABC and Telemundo, 0.7/3; CW, 0.2/1.

In total viewers: CBS, 5.6 million; NBC, 4.6 million; ABC, 3.5 million; Fox, 3.0 million; Univision, 1.9 million; Telemundo, 1.7 million; CW, 0.8 million.
