Linear swing; excellent hand-eye coordination; strong bat-to-ball skills; loose bat; quick hands; stabs with the barrel; shows an ability to adjust within a plate appearance; gets out in front of breaking pitches, but capable of spoiling offerings when beat because of hand-eye coordination.
Linear swing without leverage; lacks present strength -- and I don't see him adding much -- for over-the-fence power; raw power isn't there for more power, even when selling out to pull side.
Above-average runner; clocked him at 4.25 home-to-first on a dig; will hold speed as he ages; instincts don't standout on the bases; projecting 8-10 stolen bases.
Smooth defender; soft hands; clean footwork; reads the ball off the bat well; capable of ranging in either direction; shows some instincts; solid actions.
Solid-average arm strength; solid-average carry; accurate throws that don't tail or sail on him; would play better at second base; could play at third base in short stints.
Rondon's ceiling could be seen with a glass half-full or half-empty approach. There is no tool at his possession that could possibly allow him to reach a high ceiling. But he does possess a carrying attribute, and that is the ability to play a solid-average shortstop, given his smooth glove and soft hands. He could play second base, too, so there is flexibility in that sense, in case he's sharing a roster with another shortstop that profiles better at the position.
The floor isn't a bad one; a high 40/utility player that can play either shortstop or second base while filling in at third base in shorter stints. Ultimately, I think that is his role on a quality team at the highest level.
If Rondon can convince me he's a plus hitter rather just an above-average one, I would buy more stock in a league average shortstop. But right now, I feel he stabs a bit too much with his swing and don't see the overall strength to become a plus hitter.
