Yewri Guillen, a shortstop in the Nationals' baseball academy in the Dominican Republic, died this morning of bacterial meningitis, the team announced on the scoreboard moments ago.
The Nationals observed a moment of silence for Guillen right before the first pitch of tonight's game with the Milwaukee Brewers. He was 18.
The Nationals' PR department is not commenting and has not released a statement on the matter at the moment, saying only it would have more information later this evening. General manager Mike Rizzo is scheduled to speak to the media after tonight's game.
The team had agreed to terms with Guillen, a switch-hitting shortstop, in February. I'll have more on this after Rizzo meets with the media tonight.
