There were 125 MLB hitters in 2019 who posted average exit velocities higher than Riley on fly balls and line drives (minimum 25 such balls in play). Another 86 were within 1 mph. So yes, “that kind of power” comes along quite often.
What doesn’t come along often is a MLB player who swings and misses pitches in the zone as often as Riley did in 2019. That problem in the hit tool is going to end his career before it starts if he doesn’t figure out how to stop being a guess hitter.
