The Atlanta Braves called up Austin Riley on Wednesday and he didn't disappoint.

The club's top prospect homered in his second Major League at-bat to lead off the fourth inning.

At the time of his promotion, Riley was leading the International League with 15 homers and 39 RBI.

"I'm speechless," Riley said. "That second at-bat, I figured he was going to challenge me a little bit. I was able to put a good swing on it."

Riley hit another drive to the edge of the warning track his next time up to the plate.
