The Tom Selleck drama series had 12.8 million viewers — an impressive haul for a Friday night — marking the best viewership for the show since it debuted in 2010. The 18-49 rating wasn’t too shabby either, matching the show’s season high. CBS also had season highs for Hawaii Five-0 and Undercover Boss. CBS might have been helped by NBC’s dark dramas being replaced by Dateline this week.
