The Rookie has not been a force in the ratings for ABC.
But the show built in the ratings thanks to a stronger lead-in on Tuesday night.
With 4.5 million total viewers and a 0.8 rating, the series built to its best total viewer tally in three months.
Before that, The Bachelor's Women Tell All special scored 6 million total viewers and a 1.6 rating.
The Voice (10.1 million/1.8 rating) and This Is Us (7.8 million/1.7 rating) were both down, but New Amsterdam (5.9 million/1.0 rating) was steady.
Over on The CW, Roswell: New Mexico (1.1 million/0.3 rating) perked up with an original lead-in, while The Flash (1.7 million/0.6 rating) was steady.
Roswell should snag a sophomore run because it's performing well enough.
