At ABC, “The Bachelorette” (1.7/5 in 18-49, 5.6 million viewers overall) held steady from last week to place second to “The Voice” from 8 to 10. And at 10, “Mistresses” (1.4/4 in 18-49, 4.3 million viewers overall) was up from its unremarkable bow of last week (1.2/3 in 18-49) to become this summer’s first new scripted series to grow in the demo from its premiere. In the nation’s three biggest markets (New York, Los Angeles and Chicago), “Mistresses” beat out “The Winner Is…” in adults 18-49.
