Orioles' Jorge Mateo: Plays catch Thursday

Mateo (concussion) played catch on the field at Rogers Centre in Toronto on Thursday, Matt Weyrich of The Baltimore Sun reports.

Mateo was placed on the 7-day concussion injured list Monday after his teammate, Cedric Mullins, inadvertently hit him with the bat in the back of the helmet while in the on-deck circle. It's not clear yet whether Mateo will have a chance to return when first eligible June 10, but him being able to travel with the team and take part in some baseball activities is a encouraging sign.
