ABC Family’s new drama “Stitchers” — the network’s first real attempt at a procedural — opened to decent but unexceptional ratings Tuesday behind the still-potent “Pretty Little Liars,” which was television’s top-rated show in some of its target demos. The cable standout of the night, meanwhile, may have been USA reality series “Chrisley Knows Best,” which surged to series highs with its third-season premiere.

The network will issue “Live+3” ratings next week, but in Nielsen’s “live plus same-day” estimates, ABC Family’s “Stitchers” averaged a 0.53 rating in adults 18-49 and 1.28 million viewers overall in the 9 p.m. hour. It retained half the 18-49 audience of “Pretty Little Liars,” which kicked off its sixth season with a 1.06 rating in the demo and 2.38 million viewers overall. As might be expected for a crime procedural, it fared best among the older demo of adults 25-54, holding 55% of “Liars” (0.47 vs. 0.86).  “Stitchers” also attracted about 200,000 men 18-49, making it ABC Family’s top-rated premiere in the demo in four years.

A year ago, “Chasing Life” opened to the same 0.53 demo rating (out of a slightly stronger 1.11 for “Pretty Little Liars”) and ended up performing well enough to earn a second season. Where “Stitchers” did not fare as well was in younger demos, as it retained 38% of the women 18-34 audience from “Liars” (0.87 rating vs. 2.31) compared with a 46% hold last year for “Chasing Life,” which had a considerably stronger 1.27 rating behind a 2.77 for “Liars.”

“Stitchers,” which centers on a secret program that hacks into the brains of the recently deceased to solve crimes, tied with “Chrisley Knows Best” as the No. 1 cable program for its time period in women 18-34 and was No. 1 outright in female teens and females 12-34.

As for “Pretty Little Liars,” its audience unsurprisingly appears to be aging along with it, though it continues to rank among cable’s top scripted programs in multiple categories. Among all cable programs on Tuesday, the drama ranked No. 1 in adults 18-34, teens 12-17 as well as key demos of females 12-17, females 12-34, women 18-34 and women 18-49.

For all of television on Tuesday, “Liars” ranked No. 1 in females 12-17, females 12-34, and women 18-34, and placed No. 2 (behind only NBC’s “America’s Got Talent”) in adults 18-34 (1.4 rating).

“Pretty Little Liars” was easily the night’s most-social TV show, with a Twitter TV audience of 3.8 million people generating 19.9 million impressions. It was also Tuesday’s most engaging cable program with nearly 1.4 million engagements, including 684,000 on Instagram and 589,000 on Facebook. “Stitchers” was the No. 2 scripted show on Twitter (behind “Liars”), generating more than 1.2 million impressions from nearly 461,000 people.

USA’s “Chrisley,” a reality series about a Georgia millionaire and his family, was cable’s No. 3 original program on the night in 18-49 (0.85 rating), No. 2 in women 18-49 (1.1) and No. 1 in women 25-54 (1.4). The show surged above its second-season premiere last October, by 20% in 18-49 (0.85 vs. 0.71), 35% in women 25-54 (1.31 vs. 0.97) and 39% in total viewers (2.25 million vs. 1.62 million).

Discovery’s “Deadliest Catch” ranked No. 1 for the night among cable shows in 18-49 (1.2 rating) as well as adults 25-54 (1.5 rating) and some key male demos. And it ran second to “America’s Got Talent” among all television shows last night in men 18-49 and men 25-54.
