The New York Yankees say shortstop Gleyber Torres has tested positive for COVID-19 despite being fully vaccinated and previously having the virus.

Torres was placed on the COVID-19 injured list prior to Thursday night's game.

The announcement follows seven positive COVID-19 tests on the Yankees coaching and support staffs. 

Torres sat out Wednesday's game. Miguel Andújar was called up from Triple-A Scranton/Wilkes-Barre as a corresponding move.

"Certainly unexpected," says Yankees GM Brian Cashman. "I think everyone, MLB, in charge of the testing is looking into that and the variants that could be out there."

A statement says Major League Baseball, medical experts and the New York state Department of Health are advising and assisting the team amid additional testing and contact tracing.
