Merritt will start Thursday's game in Detroit, MLB.com's Jordan Bastian reports.
The Indians have shaken up the rotation over the rest of the season after clinching the division Monday. It's unclear how deep Merritt will be able to go Thursday, as he hasn't started a game since Sept. 2 with Triple-A Columbus. He notched just 92 strikeouts in 143.1 innings at Triple-A this year, so he comes with minimal upside as a streaming option Thursday.
