Tuesday TV Ratings 3/17/26: World Baseball Classic Final Dominates and Rises 80% from 2023, RJ Decker Collapses, High Potential Ties Series Low [+ Analysis]

Fox's broadcast of the World Baseball Classic Final (2.66) dominated on Tuesday night, outpacing all other competitors and seemingly causing significant declines on the other networks. This was likely the case on ABC as Will Trent (0.27, -0.04) and High Potential (0.25, -0.05) weakened, and newcomer RJ Decker (0.13, -0.10) collapsed. NCIS (0.27, -0.10) and NCIS: Sydney (0.15, -0.07) also plummeted on CBS, but NCIS: Origins (0.22, -0.03) had a more mild drop. NBA on NBC (0.24) was way down from last week, while the CW's WWE NXT (0.07, -0.01) dipped slightly.
