Scherzer, 35, was activated from the injured list on Thursday to start against the Rockies. He had missed two and a half weeks due to a mid-back strain. The rhomboid muscle connects the scapula with the vertebrae of the spinal column. Scherzer’s two recent injuries may be related.
Scherzer owns a 9-5 record with a 2.41 ERA and a 189/25 K/BB ratio in 134 1/3 innings.
Fedde, 26, started in Scherzer’s place while he was on the IL last time. Across eight starts and five relief appearances this season, Fedde has a 3.40 ERA with 26 strikeouts and 21 walks in 50 1/3 innings.
