Boone did not identify the staff member, claiming he was part of the team’s support staff. Another staff member was not available due to contact tracing.
That brings the total number of cases among the Yankees travel group to nine since Monday, including shortstop Gleyber Torres, who was placed on the COVID-19 injured list. Other identified cases were pitching coach Matt Blake, third base coach Phil Nevin and first base coach Reggie Willits, as well as five staff members.
“We’re doing our best with it,” Boone said. “Fortunately, he’s another who feels good. So we will continue to try to be vigilant and manage this as best we can. “
The Yankees will be traveling another staff member with the team to Texas. The last member of staff who tested positive is quarantined in Baltimore.
On Thursday, the Yankees announced that Torres had tested positive for the coronavirus while fully vaccinated and previously had COVID-19. He’s in quarantine in Tampa, Florida.
“I’m grateful that we have so many good people who have not only taken on different, heavier or greater responsibilities, but who have also taken on responsibilities that are not necessarily within their expertise,” said Boone. “We had to share the load a lot. We’ve had people who had to come here and plug in directly, and really proud of everyone and the way they handled it.
In addition, outfielder Aaron Hicks was placed on the 10-day injury list on Sunday, retroactive to Thursday, after tearing a tendon sheath in his left wrist. The club tried to treat the injury with medication. It is not known if Hicks will need surgery.
“When he tried to swing both sides of the plate it wasn’t what he was looking for or what we were looking for,” said Boone.
In a matching move, the Yankees promoted outfielder Ryan LaMarre from Triple-A Scranton / Wilkes-Barre. He starts Sunday’s game in central field.
