Jorge Mateo went 0-for-3 with two strikeouts in the first game of a rehab assignment with Triple-A Norfolk on Wednesday.
Mateo last played for the Orioles on June 6, when he was shut down because of soreness in his surgically repaired elbow. He then suffered a bad hamstring strain on June 29 while rehabbing at Norfolk, but it looks like he will be back for the final month of the season. He’ll probably replace Luis Vázquez once the Orioles deem him ready.
