Scouting Report: At the plate, Rivera is a consistent gap-to-gap hitter who puts together good at-bats and finds ways to put balls in play. He has yet to show much in-game power, with only 18 home runs in his two full seasons combined, but he shows average raw power in batting practice. He may get more over-the-fence power as he advances and gets more loft in his swing, but that's not his game as he wants to hit for a high average and move runners. Defensively, Rivera has the range and hands to handle third base. He has a plus arm but doesn't always show it off because he tries to make everything look easy. A below-average runner who doesn't steal a lot of bases, Rivera is smart and knows how to run bases.
The Future: Rivera should be ready to move to Double-A in 2019, which will be a good test. The biggest question remaining will be to see if he can develop at least a touch more power to better profile at third base.
