The Boston Red Sox have placed right-hander Nathan Eovaldi on the 10-day injured list with a right calf strain.

Eovaldi was the team's Opening Day starter and is 2-2 with a 4.98 ERA in six starts. The move is retroactive to August 26.

The injury to Eovaldi is the latest in a series of maladies that have decimated Boston's starting rotation.

Neither Chris Sale nor Eduardo Rodriguez has pitched in a game this season. Sale had Tommy John surgery on his left elbow, while Rodriguez has been diagnosed with myocarditis that is believed to be due to him having had the coronavirus. Both will miss the entirety of the season.

The Red Sox, owners of the worst record in the American League, will turn to 30-year-old righty Chris Mazza on Saturday. Mazza (0-1, 6.35) was recalled from Boston's alternate training site.
