The Atlanta Braves are promoting top third base prospect Austin Riley on Wednesday, according to multiple reports.

Riley, 22, has homered 13 times in his last 18 games at Triple-A Gwinnett, including a grand slam Tuesday at Buffalo. He is batting .299 with 15 homers, 39 RBIs and 32 runs in 37 games.

Outfielder Ender Inciarte left Tuesday's 14-3 loss to the St. Louis Cardinals with tightness in his lower back and is likely headed to a stint on the 10-day injured list.

Riley has been blocked at third base in Atlanta by Josh Donaldson, but Inciarte's injury opens a spot for him in left field with Ronald Acuna Jr. shifting to center.

A first-round pick by the Braves in 2015, Riley batted .294 with 19 home runs, 30 doubles and 70 RBIs across three minor league levels in 2018.
