Height and weight is accurate; good athlete; high waist; tree-trunk legs; body resembles his uncle Vlad; strength throughout; physically mature at 20; could see him gaining some bad weight in a couple years.
4/17, 4/18, 5/6, 5/22
High Desert Mavericks (High A, Mariners)
50; Second-division RF
Closed stance; very loose hands/arms; bat speed is plus; hand-eye coordination is very good; can put the barrel on the ball in any quadrant in the strike zone and even outside the zone; has a knack for hard contact; enjoys fastballs; pitch recognition and approach is getting better; chases often still; doesn't like to keep the bat on his shoulder; plus bat-to-ball skills, strength, and a better feel for hitting (which will come with time) should allow him to hit around .275-285 at the highest level.
Raw power is above-average; doesn't display it in BP often, but he's capable of hitting tape measure blasts; creates leverage and backspin; slight uppercut; mostly line-drive hitter at the moment; plus strength; back leg can slip out of the box (lunging) while he swings which can sap some power; don't see a ton of homers like his uncle, but middle 20's in home runs isn't out of the question.
Clocked 4.25 to 1st; moves well for his size on the bases and in the field; good base runner; 14 for 16 in steal attempts; can go 1st to 3rd; will slow a step in a few years but speed can be a factor.
Shows good range in RF; athleticism is clear; routes can be a bit of a journey but he can make the adjustment; can boot a ball on the ground at times; don't think it would work in CF because he'll only slow down with age; corner guy only.
Arm is a weapon; throws are on a line and accurate with good carry; gets behind the ball before a throw to a base.
Guerrero has what you look for in an corner-outfield prospect; a large body with plus raw power and an above-average arm, especially one with a lineage as rich as his. He's impressed in my couple of looks this season, hitting the ball all over the field and on a line. He tends to expand the zone, and because of that still has a high risk tied to his name. The approach is getting better from previous reports though, which is promising. The next test is Double-A which will probably be late this season and all of next. If he can continue to refine his plate discipline during that time, A first-division bat will start to look a little clearer on the horizon. I like his chances.
