American Ninja Warrior went out on a high note in Monday's ratings.

The season finale of the competition series scored a 1.2 rating among adults 18-49, tying a season high and hitting the show's best mark since June 4. (The season as a whole, however, is down about 25 percent in same-day ratings versus 2017.) Ninja Warrior also racked up the most total viewers (5.63 million) in primetime, drawing its second-biggest audience of the season.

Bachelor in Paradise is currently at a season-high 1.4 for ABC, but that may not last. Network affiliates in Los Angeles, San Francisco and Detroit carried Monday Night Football, so BiP's numbers will likely come down in the finals. 

The season finale of So You Think You Can Dance on Fox drew a 0.6 in adults 18-49, up a tick from last week and on par with its season average. Salvation (0.4) improved slightly for CBS after nine consecutive weeks at 0.3, but Elementary came down a tenth of a point from last week's 0.4. The network's fall preview special posted a 0.7 at 8:30 p.m.

ABC currently leads the network standings with a 1.2 in the 18-49 demo, pending updates. NBC stands second at 1.0. Fox averaged 0.6, CBS 0.5 and The CW 0.3, pending updates for an MNF preemption in New York City.

The Late Show posted its best metered-market household rating (3.0) in five months for Stephen Colbert's interview with journalist Bob Woodward, doubling both The Tonight Show and Jimmy Kimmel Live (1.5 each). Tonight and The Late Show tied for the 18-49 lead at 11:35 p.m. with 0.5s, while JKL was a tenth behind at 0.4.

Late Night led the demo at 12:35 a.m. with a 0.3. Both The Late Late Show and Nightline came in at 0.2.

In the finals, Bachelor in Paradise did indeed adjust down, matching last week's 1.1.

Final network averages are NBC, 1.0; ABC, 0.9; Fox, 0.6; CBS, 0.5; and The CW, 0.2.
