The Rockies have placed right-hander Jon Gray on the 10-day injured list, retroactive to Sept. 2, with shoulder inflammation, the team announced. They recalled righty Jose Mujica to take Gray’s roster spot.
Shoulder issues can lead to lengthy absences for pitchers, so it’s unclear whether Gray will return this season. Regardless, the 28-year-old – who was a key part of the Rockies’ rotation during previous seasons – has struggled in 2020 for the playoff contenders. Gray has averaged fewer than five innings per start (39 frames in eight appearances) and recorded career worsts in ERA (6.69), FIP (5.01), strikeouts per nine (5.08), groundball rate (36.7 percent) and average fastball velocity (94 mph).
Aside from Gray, the Rockies have given multiple starts to German Marquez, Antonio Senzatela, Kyle Freeland and Ryan Castellani this year. Marquez, Senzatela and Freeland have been respectable overall, while Castellani has allowed two or fewer earned runs in four of six appearances. A pair of five-run blowups have damaged his numbers, though.
