The Braves will promote top third base prospect Austin Riley, The AJC confirmed early Wednesday.

Outfielder Ender Inciarte exited Tuesday’s game with lower back tightness and will likely require a stint on the injured list, opening the door for Riley.

Riley, the team’s consensus top position prospect, has started four of the past six games in left field for Triple-A Gwinnett. He’d presumably man that spot in the majors, shifting Ronald Acuna to center in Inciarte’s absence.

The 22-year-old Riley hit a grand slam Tuesday, continuing what’s been the hottest streak in the International League. He’s homered 15 times in 144 at-bats, and in 13 of his past 18 games.
