Prospect scouting: Padres' Guerra looks smooth afield, Dodgers' Diaz loaded with upside

Many people feel that San Diego Padres shortstop prospect Javier Guerra was the true gem of the Craig Kimbrel trade, and I got a good look at the 20-year-old recently. While just a 45 runner on the 20-80 scouting scale based on my observations, Guerra's actions, footwork and paths to balls in play are all so efficient and smooth that he's a no-doubt shortstop -- and probably a plus there eventually -- despite not being a burner. In the game I saw him, he made several acrobatic plays, including one on a ball toward the hole to his right which he back-handed before making a strong, accurate, spinning jump-throw to second base for a force out.

Offensively, Guerra is a bit overzealous right now, swinging and missing pitches he has no business offering at in the first place. He has a 32 percent strikeout rate, which is purely an approach issue and not one born of his swing; Guerra has pretty good bat control, can get to balls down and in well and has sneaky power for someone his size because of the strength in his wrists. He should have average game power at maturity which, given his prowess at shortstop, could make him a star if he hits enough to tap into it.
