Thursday night’s battle of the competition premieres left neither really strutting their stuff. The two-hour 8 PM time slot premiere of Fox’s So You Think You Can Dance(2.4/8) saw a misstep from last year. SYTYCD was down 27% from last year’s season opener. Going toe to toe with SYTYCD in the slot was ABC’s Duets (1.7/5) With American Idol winner Kelly Clarkson, John Legend and Sugarland’s Jennifer Nettles as judges, Duets can lay claim to some serious singing star power. ABC’s new singing competition show was up 8% over SYTYCD in total viewers, though Fox dominated the Adult 18-49 demo by 41%. Duets brought in around 6.7 million total viewers over the two hours  to Fox’s approximately 6.2 million. However, Duets was down 29% from last year’s Expedition Impossible premiere but that still made it ABC’s biggest audience in the slot on a post-season Thursday in 4 years.

With the season over and heading into the Memorial Day weekend, it was a night of repeats on NBC that paid off for the finale of Awake (0.9/3) The now canceled police procedural’s season one closer was up 29% from last week’s season low. Over on ABC in the same 9 PM time slot, the third season of Rookie Blue (1.4/4) started off down 13% from last year’s premiere.

In a night of repeats on CBS the 8 PM The Big Bang Theory (2.3/8) repeat drew over 8.2 million viewers. That was followed by 6.2 million watching Rules of Engagement (1.7/6) 7.8 million watching Person of Interest (1.4/4) and just a little more watching The Mentalist (1.5/4).

Fox was tops among Adults 18-49 but CBS won the night in terms of total viewers.
