In this story:


The Washington Nationals will reportedly select the contract of pitcher Andrew Alvarez so he can make his MLB debut on Monday against the Miami Marlins.  

Nationals interim manager Miguel Cairo told reporters before Sunday’s game that Alvarez would get the start. Nats Report first reported the potential move. Their report also noted that Washington would promote infielder Nasim Nuñez from Triple-A Rochester.

Neither move isn’t official yet and won’t be until Monday. Nuñez is already on the 40-man roster and only requires a 26-man move to clear space. The Nationals will have to select Alvarez’s contract from Triple-A Rochester and make both a 40-man and 26-man move to make room.

Washington needed a starter after it placed top left-hander MacKenzie Gore on the 15-day injured list with left shoulder inflammation. He could return sometime this season, but the Nationals don’t intend to rush him. Gore, who was an All-Star this season, is 5-13 with a 4.15 ERA in 27 starts. His 173 strikeouts are among the most in the Majors for any starting pitcher.
