NBC’s “The Voice” continues to look a bit tired this spring, matching or coming pretty close to a series low Tuesday even as it remained the night’s top program in young adults. The net’s comedies “About a Boy” and “Growing Up Fisher” also won their timeslots to lift the Peacock to a demo victory on a night when the CBS dramas aired in repeat.

According to preliminary national estimates from Nielsen, “The Voice” averaged a 2.7 rating/9 share in adults 18-49 and 11.0 million viewers overall for its live-elimination episode, down 10% from last week’s national number (3.0); if it stays at a 2.7 in the nationals, it would mark a regular-timeslot series low for the music competition. Still, it won its hour and the night in 18-49 and 25-54 (2.4/6).

“The Voice” was followed by original episodes of “About a Boy” (1.9/6 in 18-49, 7.2 million viewers overall) and “Growing Up Fisher” (1.5/4 in 18-49, 6.0 million viewers overall), which were in line with last week and again led their timeslots in adults 18-49. A repeat “Chicago Fire” capped the night (0.9/3 in 18-49, 4.3 million viewers overall).

CBS aired repeats of “NCIS” (1.2/4 in 18-49, 10.4 million viewers overall), “NCIS: Los Angeles” (1.4/4 in 18-49, 10.2 million viewers overall) and “Person of Interest” (1.1/3 in 18-49, 7.6 million viewers overall) but still finished third among the broadcasters in 18-49 and second in 25-54 while winning easily as usual in total viewers.

Univision ranked second on the night in 18-49, led at 9 p.m. by Lo Que la Vida Me Robo (1.5/4 in 18-49, 3.8 million viewers overall).

At ABC, “Marvel’s Agents of SHIELD” (1.8/6 in 18-49, 5.7 million viewers overall) was down in the demo from its special 9 p.m. airing of last week, but up a tick from its prelim score of two weeks ago when it aired at 8; it also was up about 15% from its prior 8 p.m. episode in total viewers, picking up some older viewers from CBS courtesy of its “NCIS” repeat. “SHIELD” tied “The Voice” for the 8 p.m. hour’s lead in men 18-49 (1.8/6) while winning outright in men 25-54 (2.5/7).

“SHIELD” was followed on ABC by repeats of “The Goldbergs” (0.9/3 in 18-49, 3.1 million viewers overall) and “Trophy Wife” (0.6/2 in 18-49, 2.1 million viewers overall) and an original “Celebrity Wife Swap” (0.9/3 in 18-49, 3.0 million viewers overall), which was within a tenth of its premiere of last week.

Fox’s “Glee” (0.9/3 in 18-49, 2.5 million viewers overall) was down a tick in 18-49 from last week, and was followed by a repeat “New Girl” (0.6/2 in 18-49, 1.4 million viewers overall) and an original “The Mindy Project” (1.0/3 in 18-49, 2.1 million viewers overall). “Mindy” matched its week-ago score when it aired behind an original episode of “New Girl.”

At CW, “The Originals” (0.6/2 in 18-49, 1.4 million viewers overall) was down a tenth from last week, while “Supernatural” (0.9/3 in 18-49, 2.2 million viewers overall) rose two tenths and tied with CBS and NBC for first among the English-language broadcasters for its hour in men 18-34 (0.7/2).

Preliminary 18-49 averages for the night: NBC, 1.8/5; Univision, 1.3/4; CBS, 1.2/4; ABC, 1.1/3; Fox, 0.9/3; CW, 0.8/2; Telemundo, 0.4/1.
