Red Sox place Michael Wacha on 15-day injured list, recall Tyler Danish from Triple-A Worcester

Wacha had been slated to start Sunday’s series finale against Chicago at Fenway Park, but was scratched shortly before first pitch due to what Boston manager Alex Cora described as left side soreness.

At that time, Cora was hopeful that Wacha would be able to pitch in Texas next weekend since he underwent an MRI on Saturday that came back clean. Cora also told reporters (including MassLive.com’s Christopher Smith) that the Red Sox were being cautious with the 30-year-old hurler since he has a prior history of oblique injuries.

Since his stint on the injured list was backdated to May 5, the soonest Wacha could return to the mound for the Red Sox is May 20. This means that he will not be available for next weekend’s series against the Rangers as Cora had originally hoped.

Through five starts for Boston this season, Wacha has posted a miniscule 1.38 ERA and 3.89 FIP to go along with 19 strikeouts to 11 walks over 26 innings of work. The 6-foot-6, 215 pound righty led the Sox in bWAR (1.4) coming into play on Sunday.

With Wacha sidelined, Tanner Houck started in his place in Sunday’s series finale and allowed three runs on four hits, no walks, one hit batsman, and two strikeouts across just 2 2/3 innings pitched. It seems likely that Houck will take Wacha’s spot in the starting rotation for the time being.

Danish, meanwhile, re-joins the Red Sox for the third time this season after previously being used as a COVID-related substitute on two separate occasions. The 27-year-old made his fifth relief appearance of the year on Sunday and has now produced a 3.18 ERA with seven strikeouts and two walks over 5 2/3 total innings at the big-league level.
