Two short reports on D:
On defense, Soto looks comfortable roaming the outfield. He is quick but not especially fast, typically taking consistent and efficient routes to fly balls. He has a solid arm, but not a prototypical right-field arm, and could end up in left as he climbs the ladder.
Defensively is not where Soto makes his name as a prospect, as his average speed and athleticism, along with fringe-average arm, allows him to play a reasonable but unexceptional right field. As he matures and receives additional game experience, I could envision his arm getting to average, as well as his overall defense in right field. However, if he loses much speed or range as he ages, he could profile better long-term in left field, where he would project as average or slightly better.
