ABC Family’s bid to gain traction in comedy took a step forward Wednesday night with solid ratings for the new “Baby Daddy” and returning “Melissa & Joey.”

According to Nielsen, “Baby Daddy” opened as the net’s No. 2 comedy premiere to date in total viewers (1.65 million), adults 18-34 (619,000) and adults 18-49 (935,000), among other categories. It was cable’s top-rated program Wednesday in femmes 12-34 (679,000), building slightly on “Melissa & Joey” (646,000).

And in its 8:30 p.m. slot, “Baby Daddy” also led all of cable in women 18-34 (492,000) and women 18-49 (732,000).

Kicking off the night, “Melissa & Joey” drew a season-high 1.49 million viewers, and attracted the largest women 18-34 audience (510,000) in the show’s 36 episodes to date.

“Melissa” stood as TV’s top-rated scripted telecast in the 8 o’clock half-hour in women 18-34 and femmes 12-34.

Elsewhere, TNT’s “Dallas” (1.3 rating/4 share in adults 18-49, 4.76 million viewers overall) declined by 17% in 18-49 from its potent premiere of last week, and was television’s No. 1 scripted original for the night in 18-49, 25-54 (1.6/4) and total viewers. It didn’t hold up as well among viewers 50 and older, contributing to a roughly 30% decline in total viewers from its premiere (6.86 million).
