Thursday TV Ratings 5/26/22: Grey’s Anatomy Rises for 400th Episode Finale, Welcome To Flatch Remains Pitiful on Finale Night (UPDATED)

Ratings Analysis: ABC drama 'Grey's Anatomy' (0.65, +0.05) rose by five-hundredths for a 400th episode that also doubled as its season finale. 'Grey's' was easily the highest-rated program on a night full of reruns and led into an encore of 'The Rookie' (0.23). CBS had repeats of 'Young Sheldon' (0.40), canceled 'United States of Al' (0.36), 'Ghosts' (0.24), and 'B Positive' (0.24). In the 10PM hour, drama 'Bull' (0.32, -0.02) quietly ended its six-season run by losing two-hundredths. On the Fox network, 'MasterChef Junior' (0.31, -0.07) slipped to a new series low while 'Welcome To Flatch' (0.15/0.15) was steady at 9 and up by three-hundredths at 9:30 when compared to last week's batch of episodes (0.15/0.12). 'Flatch' was the only other season finale aside from 'Grey's' and will be back for season two despite laughable ratings. NBC had repeats of 'Celebrity Escape Room' (0.37), 'Law & Order: SVU' (0.34), and 'Law & Order: Organized Crime' (0.25). The CW had anemic reruns of 'Walker' (0.03) and 'Legacies' (0.01).

Finals Update: Repeats of 'Celebrity Escape Room' (+0.1) and 'United States of Al' (+0.1) adjusted up.
