Díaz hit .169 with five home runs and 11 RBIs in 58 games this year for the Miami Marlins. The Pittsburgh Pirates claimed him off waivers from the Marlins last month, then the Orioles claimed him off waivers from the Pirates in early December.
Baltimore designated Díaz for assignment earlier this week when the team acquired reliever Mychal Givens.
Díaz made his big league debut in 2020 for the Marlins. He has hit .181 in 112 games.
