Fox ruled Wednesday’s primetime ratings race behind “Empire,” even it did fall a little to its lowest numbers since November, while a special preview of NBC’s fitness reality show “Strong” looked rather weak ahead of its move to Thursdays. CBS rookie “Criminal Minds: Beyond Borders” took advantage of its weakened timeslot competition to post best-since-premiere numbers as it continues to look solid after five weeks.

According to preliminary national estimates from Nielsen, “Empire” averaged a 3.8 rating/12 share in adults 18-49 and 10.0 million viewers overall in the 9 o’clock hour, down abpout 10% from last week. While this demo score figures to be high enough to finish No. 1 for the week, this represented the show’s second lowest score to date (behind only a Thanksgiving eve episode that did a 3.2). One week after having the penultimate episode of “American Idol” as its lead-in, “Empire” last night more than tripled its lead-in from “Rosewood” (1.2/4 in 18-49, 4.4 million viewers overall), which was down 0.2 from its prior original (on the night of the “Empire” return).

NBC opened with a special results edition of “The Voice” (1.7/6 in 18-49, 8.8 million viewers overall), which led its hour in total viewers but finished a little behind CBS and ABC for the hour in 18-49. It was followed by the two-hour preview of “Strong” (1.0/3 in 18-49, 3.4 million viewers overall), a fitness competition series executive produced by Sylvester Stallone. While NBC doesn’t put too much weight on ratings for its previews, it’s hard to imagine the show doing too much when it moves to its regular 8 o’clock timeslot tonight when its competition will include the likes of “The Big Bang Theory” and “Grey’s Anatomy.”

At CBS, “Survivor” (1.9/7 in 18-49, 8.5 million viewers overall) was unfazed by special competition from “The Voice,” as it held steady at what is its season low. It was followed by “Criminal Minds” (1.7/6 in 18-49, 9.0 million viewers overall), which was down a tick from its prior original to hit a season low — even though crime drama competition “Law & Order: SVU” on NBC had the night off. Closing things out, “Criminal Minds: Beyond Borders” (1.5/5 in 18-49, 8.0 million viewers overall) dominated its hour and was up 25% (0.3) from last week when it aired a pair of episodes; in both 18-49 and total viewers, this was the Gary Sinise-fronted drama’s best showing since its March 16 premiere.

At ABC, “The Middle” (1.7/6 in 18-49, 6.8 million viewers overall), “The Goldbergs” (1.8/6 in 18-49, 6.2 million viewers overall), “Modern Family” (2.2/7 in 18-49, 7.4 million viewers overall) and “Black-ish” (1.6/5 in 18-49, 5.7 million viewers overall) were mostly steady as they hovered at or near their season lows, with “Modern” the night’s No. 2 scripted program in key demos. “Nashville” (1.0/3 in 18-49, 4.2 million viewers overall) was up a tick at 10.

CW aired repeats of “Arrow” (0.3/1 in 18-49, 1.1 million viewers overall) and “Supernatural” (0.3/1 in 18-49, 0.9 million viewers overall).
