CLEVELAND — Boston Red Sox infielder Kiké Hernández has tested positive for COVID-19 and will be sidelined indefinitely.

Manager Alex Cora said Hernández is experiencing symptoms. He’ll be placed on the COVID-19 list along with second baseman Christian Arroyo, who had close contact with Hernández.

“They’ll be out for an extended period of time,” Cora said Friday night before the Red Sox opened a three-game series against the Indians.

Cora would not divulge whether Hernández is vaccinated.

Cora said infielders Yairo Munoz and Jonathan Arauz were recalled from Triple-A, and the Red Sox were hoping they would arrive in time to be available Friday night.

With COVID-19 cases on the rise across the country, MLB teams have seen a recent jump in infections as well.

“It’s something we’re dealing with in our world, and outside our world. I don’t want to say that we’re lucky that we’ve been OK throughout the season, but it just happened,” Cora said. “It’s happened to a lot of teams and we’ve got to find a way to keep moving forward and keep playing good baseball.”

Cora said he’s confident the Red Sox have been vigilant in following protocols.

“We’re disciplined,” he said. “In talking to other teams, we’re probably the most aggressive team testing-wise.”

Cora said following a recent outbreak on the Texas Rangers, the Red Sox took extra measures to make sure players “were clear, sound.”

“We’re doing a good job,” he said. “This is just what we’re fighting against. It’s not Kiké’s fault. He’s been great in taking care of his family. … It’s something we can’t control. We’re fighting an invisible enemy and it just happened that he tested positive.”

WITH HIS two-run home run Thursday, Rafael Devers joined Ted Williams as just the second player in Red Sox history to record two 30 home run seasons before turning 25. Devers now has 30 home runs and 94 RBI on the season with more than a month still to play.

ALL OF FENWAY was chanting Bobby Dalbec’s name Thursday after the rookie went 3 for 4 with two home runs and a career-high seven RBI. Dalbec is batting .346 with a 1.163 OPS, five home runs and 19 RBI since the start of August.
