Jones is among the most fun to watch players in the minors. He’s a top-of-the-scale athlete who plays spectacular (albeit inconsistent) defense at several positions, and he has incredible speed and above-average raw power. Now 26, Jones still hasn’t made progress in a few key areas, namely his infield hands and arm accuracy, and his contact hitting. He hit .267/.344/.453 in his first season in the Rockies system, but K’d at a 35.5% clip, which is actually a good bit better than his 2023 rate (38.8%). Jones swings pretty hard and can tag a fastball, but he’s hapless against secondary stuff; this is the kind of guy who’d hit .180 or so with regular reps.
At a certain point it was feasible that a young, switch-hitting Jones would make meaningful progress in this area, but that hasn’t happened. Instead, it’s via his speed and defense that Jones remains relevant. Though he struggled with flubs and underthrows, Jones was developed solely at shortstop for his first four years in the Rays system and wasn’t given run in center field until 2023. Traded to Colorado for Joe Rock that offseason, he’s now been exposed to a mix of CF/SS/2B and sometimes plays all three like your friendly neighborhood Spiderman, with highlight-reel acrobatics. Too often, though, Jones is flub-prone on the infield, and his throwing is much, much better from the outfield, where his relative inexperience still sometimes shows. He’s below average at short and has played just eight games at second, but Jones is such an unbelievable athlete that I’m still betting he becomes a very special defensive center fielder in his late 20s. He still has value as a late-game runner and defender.
