Wide setup, noisy pre-pitch, inconsistent trigger; toe tap, hips leak, firm to front side, struggles with timing; above-average bat speed, strong wrists, bat gets into the zone in a hurry, ability to drive the ball to LCF, can square velocity; hyper-aggressive approach showed signs of toning down in second series look, above-average hand-eye, limited ability to get ahead of sequencing/make adjustments, no present two-strike approach
Above-average raw, swings hard; moderate leverage, swing path to lift it, ball carries off the barrel; power to opposite gap, average possible to pull side, poor approach limits in-game
4.05 with release on a bunt, below-average tool projection; high-effort running style; tentative primary and secondary leads, struggles to time pitchers, below-average base-stealing potential
Natural shortstop actions, extremely fluid, makes it look easy; quick feet, confident first step, lateral quickness offsets below-average raw foot speed; soft, strong hands, body control, seamless transfer from awkward angle; poor reads on a couple hops, non-chalant effort on multiple plays
Easy plus velocity plays up with quick transfer, ability to control trajectory and deliver accurate throws from multiple arm angles
Signed by Boston for $250,000 out of Panama in 2012, traded to San Diego in November 2015. Guerra is extremely young for his league, and it shows in an extremely raw, aggressive approach at the plate. Premier defensive tools at a premium position, along with some pop in the batter's box, combine to set a high floor for Guerra as an above-average big-league shortstop. A couple steps forward with the approach and swing consistency can put him on the doorstep of a first-division career.
