It won its time slot at 10 p.m. in the adult demographic and came in second in viewers behind CBS’ repeat of Cold Case.

Scoundrels averaged 5.17 million viewers at 9 p.m. and won its second half-hour in viewers. The two dramas also gave ABC a boost over last year in viewers and adults 18-49.

Despite airing against mostly reruns on CBS and Fox, ABC still finished in third place for the night among total viewers (4.80 million). NBC – which aired the final round of the U.S. Open – averaged 7.31 million, while CBS was in second with 5.45 million. Fox, which aired mostly repeats of its animated shows except for the barely-watched series finale of ‘Til Death (1.52 million), finished in fourth place with 2.98 million viewers. Fox also aired an original episode of the canceled comedy Sons of Tucson, which mustered up 1.39 million viewers.
