Mateo slugged a two-run home run in his only at-bat during Thursday's 17-2 rout of the Diamondbacks.
The utility infielder pinch hit for DH Dominic Smith in the ninth inning and took position player James McCann deep. Mateo has been used sparingly early in the year, appearing in just three of Atlanta's first seven games and getting only four plate appearances, and it'll likely take an injury or two to put him in a fantasy-friendly role.
