"The Yankees can today confirm that INF Gleyber Torres has received a positive COVID-19 diagnosis. He was fully vaccinated and previously had COVID-19 during the most recent baseball offseason," MLB stated. Torres is asymptomatic, Yankees manager Aaron Boone said in a press conference Thursday. The MLB player is "the eighth Yankees player, coach or traveling staff member to test positive this week.

However, Coach Nevin received the Johnson & Johnson vaccination during spring training in Florida in March, the NY Times and The Athletic reported. "I think one of the things we're seeing is that being vaccinated en masse like we are, we're seeing the vaccinations also kind of blunt the effects of the virus," Boone said in a press conference on Wednesday. "I feel like in a lot of ways, because we're vaccinated, we're kind of good and able to deal with this. So there's a little bit of a frustrating part there, in all the testing that we're gonna do."

The New York State Department of Health is investigating why and how the players tested positive a month after getting vaccinated, ESPN reported. "While there have been anecdotal reports of New Yorkers who have had a positive COVID test 14 or more days after receiving their last vaccine dose, DOH is investigating those cases along with the ones linked to the Yankees further to determine if they meet the formal CDC definition of vaccine breakthrough," the NY DOH told the outlet in a statement. getty Never miss a story — sign up for PEOPLE's free daily newsletter to stay up-to-date on the best of what PEOPLE has to offer, from juicy celebrity news to compelling human interest stories.
