Since moving back to Tuesdays, FOX’s “Glee” has been exploring the proverbial ratings basement. It consequently seemed to be only a matter of time before ABC Family’s cable drama “Pretty Little Liars” outdelivered FOX’s broadcast drama in key viewership categories.

That time came Tuesday night.

The “Pretty Little Liars” season finale, which aired opposite “Glee'”s milestone 100th episode, posted a solid 1.3 adults 18-49 rating with 3.12 million viewers.

Tuesday’s “Glee” only drew a 1.1 rating with 2.80 million.

Despite facing a weaker installment of “Glee,” last week’s “PLL” failed to win the head-to-head battle. It posted a 0.8 adults 18-49 rating with 1.95 million viewers.
