Ten Days in the Valley is on the move at ABC.

The freshman drama is shifting from Sundays to Saturdays after four episodes, The Hollywood Reporter has confirmed.

The series will move to Saturdays beginning Dec. 16. Two episodes will air back-to-back on that date, followed by a new episode at 10 p.m. on Saturday, Dec. 23, as well as Dec. 30. The two-hour season, and likely series, finale will then air on Saturday, Jan. 6, at 9 p.m.

Beginning Sunday, Oct. 29, ABC will fill Ten Days' Sunday at 10 p.m. timeslot with Shark Tank encores.

Star Kyra Sedgwick first announced the news on her Twitter page Thursday.

The news is not surprising given the drama's low ratings thus far. The serialized series, which centers on a TV producer whose daughter goes missing, opened to a modest 0.5 rating in the adults 18-49 demo. The series saw little lift when seven days of delayed viewing factored in, ticking up to just a 0.7. The most recent new episode, airing Oct. 22, drew a 0.4 rating.

Sedgwick, who is also an executive producer on the series, had been vocal about ABC's lack of promotion for the series, which marked her first series regular role since TNT's The Closer.

"The biggest difference is that there's tons more shows and there's a lot more competition, you know? I also think ABC's not doing a good job getting the word out there," she told The Daily Beast in September. "The truth is that no one knows [Ten Days in the Valley] is on. So that’s disturbing and scary.”

Sedgwick won an Emmy for her role on The Closer, which ran seven seasons and spawned a spinoff, which is set to wrap in 2018.

Ten Days in the Valley is the first freshman series to be moved. While broadcast networks once simply canceled low-rated series, in recent years, they have opted to keep even lower-performing series on the air to complete the run, moving them to less high-pressure nights (like Ten Days) or trimming the number of episodes ordered. (Not helping Ten Days' chances was the fact that it was not produced in-house and instead hailed from Skydance Media.)

However, ABC has also had success with fellow freshman drama The Good Doctor, which has soared on Mondays following Dancing With the Stars and earned a five-episode pickup after just two episodes. Other first-year series that have earned pickups include CBS' Young Sheldon and SEAL Team. ABC has not yet made decisions on its rookie offerings, which include comedy The Mayor and light hourlong Kevin (Probably) Saves the World.
