Braves prospect Eric Hartman’s power-speed breakout puts him among rare company

Eric Hartman, a top prospect in the Atlanta Braves system, has reached a rare power and speed combination that places him near the top of MLB’s modern developmental history. In the span of his pro career, Hartman became the second-fastest player in almost two decades to reach 20 home runs and 30 stolen bases, a benchmark that typically takes either a long path to develop both skills or a prospect who arrives with both tools already advanced.

The Braves drafted Hartman in the 20th round in 2024. He is from Alberta, Canada, and at the age of 19 during his early professional season, he was still working through the usual adjustments of a new level of pitching while trying to stay aggressive on the bases. According to the Braves’ organization coverage from earlier in his rise, he had spent time dealing with the bumps that come with a young prospect season, including a stint on the injured list that affected when he could return to game action.

Exactly one year before this milestone announcement, Hartman was preparing to rejoin Single-A Augusta after that injured-list stint. At that point in his progression, his early pro line reflected the growth stage he was in, with a batting average of.222 and a.710 OPS through his first 39 games. That context matters because the “20 homers, 30 steals” storyline is not just about raw production, it is about maintaining the ability to create extra-base impact while still running well enough to turn games into multi-tool opportunities.

What makes the milestone stand out is that power and speed at this level do not always develop together. In many systems, prospects either grow into consistent extra-base power later while their stolen-base attempts become more selective, or they remain more purely athletic while their slugging lags behind. Hartman’s pace to 20/30 suggests he has been able to connect on mistakes deep in the zone and, at the same time, sustain enough baserunning confidence and success to turn those at-bats into stolen-base production.

For the Braves, a development profile like Hartman’s is valuable because it fits how teams build middle-of-the-order and game-breaking upside in the minor leagues. A player who can impact both categories forces opposing defenses to make different tactical choices, whether it is pitch selection with a runner in motion or managing the risk of giving up extra bases after contact.

The immediate next step for a prospect reaching this kind of marker is less about a single number and more about whether the underlying approach holds as competition rises. The question to watch is whether Hartman can keep the same blend of patience, power, and aggressiveness as he faces more advanced pitching, and whether his stolen-base success stays high enough that teams remain comfortable giving him the green light.

As MLB’s prospect ranks continue to highlight a select group of players with true two-way offensive profiles, Hartman’s ascent provides a concrete example of the kind of developmental payoff evaluators look for: not only ceiling in one category, but repeatable production that pairs impact at the plate with the ability to turn speed into additional scoring chances.
