The Red Sox have placed right-hander Josh Winckowski on the COVID-19 related injured list. In a corresponding move, left-hander Darwinzon Hernandez has been recalled from Triple-A Worcester, the club announced prior to Thursday’s series finale against the Rays.

Winckowski, who is vaccinated against COVID-19, has tested positive for the virus. The 24-year-old could be out for the next 10 days, though he could return sooner if he registers two negative PCR tests, goes more than 24 hours without a fever, and receives approval from Major League Baseball’s joint medical committee.

Since making his major-league debut in May, Winckowski has made seven starts for the Red Sox, posting a 4.38 ERA and 4.25 FIP to go along with 26 strikeouts to 14 walks over 37 innings of work. Considering that the rookie hurler started against the Rays on Wednesday, he was unlikely to pitch again before the All-Star break.

While on the COVID-19 related injured list, Winckowski will not count against Boston’s 40-man roster, which currently sits at 39 players.

Hernandez, meanwhile, returns to the Red Sox for the first time this season. The 25-year-old southpaw did not make the Opening Day roster out of spring training and was instead sent down to Worcester to work on a starter’s schedule.

Seven starts into his season with the WooSox, Hernandez suffered a torn right meniscus that ultimately required him to undergo knee surgery in late May. The native Venezuelan was sidelined for a little more than two months before being activated from Worcester’s injured list on July 4.

In four relief appearances for the WooSox since then, Hernandez has yet to allow a run while scattering two hits, two walks, and six strikeouts across 3 1/3 innings out of the bullpen.

With the Red Sox last year, Hernandez posted a 3.38 ERA and 4.80 FIP with 54 strikeouts to 31 walks over 48 outings spanning 40 innings of relief.
