General manager Brian Cashman revealed Montgomery’s positive test during a radio interview before a game against the Baltimore Orioles at Yankee Stadium.
The All-Star ace Cole was expected to start, but manager Aaron Boone revealed the right-hander’s positive test after a 7-1 loss to the Orioles. Cole was replaced by top prospect Luis Gil, who makes his major league debut.
Montgomery and Cole, who share the team lead with 21 starts apiece, will be out at least 10 days unless they draw two negative test results. Montgomery’s most recent start was Sunday, when he had a no-decision in a 3-1 win over Miami.
The positive tests came after the Yankees returned from a weeklong trip to Florida, which is among the states experiencing an increase in COVID-19 cases.
At least 85% of New York’s players are vaccinated. Boone says he believes it’s up to the players to decide whether they want the COVID-19 vaccine.
“I think the right thing to do is to be vaccinated,” Boone said. “I’ve said that a number of times, but in the end it’s up to individuals.”
