The Amazing Race's shocking finale Sunday did nothing to boosts its numbers.

Season 21's two-hour closer averaged 9.3 million viewers and a 2.6 in the adults 18-to-49 demographic to tie last season as the show's lowest-rated finale. Lead-out The Mentalist (7.9 million, 1.6) was down 11 percent.

NBC won the night with Sunday Night Football (18.9 million, 6.9).
