We continue our look at the Chicago Cubs’ top 20 prospects today, with our ninth-ranked prospect, outfielder Josiah Hartshorn. For a quick refresher, make sure you check out our other articles in the series:
#9 – Josiah Hartshorn (Orange Lutheran High School)
Josiah Hartshorn was the Cubs’ sixth-round pick in the 2025 draft. The team gave him a pretty massive $2-million bonus, buying him out of a commitment to Texas A&M. Hartshorn had an interesting senior year, as the switch-hitter faced both right and left elbow issues that forced him, in turns, to hit only right- or left-handed. Despite those setbacks, he was ranked within the top 100 draft prospects by MLB.com, and none of the injuries were bad enough to scare the Cubs away from the selection.
What to like:
Hartshorn displays both a good hit and power tool. For someone his age, it’s usually one or the other, but with the Cubs’ sixth-rounder, it’s both. Hitting .364 over his 29 games, the outfielder added five home runs while walking six more times than he struck out. Clearly he made a lot of contact, and the approach is somewhat advanced for his age. While the five home runs may not wow you on their own, it’s a good reminder that he dealt with a handful of injuries to his back and his elbow over his time, and spent a decent amount of it banged-up.Â
Where the power was truly on display was during the 2024 High School All-Star Home Run Derby, when he finished tied for the win with eventual 19th-round selection Jacob Parker. Don’t let his draft round fool you, though, Parker didn’t sign a contract with the Arizona Diamondbacks, and decided to go to Mississippi State instead. Parker was ranked the ninth-best incoming freshman in baseball, so his draft round was due to signability issues, not talent. That night in 2024, Hartshorn went toe-to-toe with him, forcing Parker to hit a buzzer-beater to share the title. The Home Run Derby isn’t our best data point, but it does highlight the pure power potential. He absolutely thumped some of those pitches, and if this can translate from “derby power” to “game power,” the organization could have something very fun on their hands. Â
Defensively, there’s enough athleticism and arm strength to believe he could become an average or slightly above-average right fielder. He may see some time in center field initially because he moves pretty well for his size, but he’s probably destined for the corners. His defense will never be the calling card, but an average right fielder with the type of light-tower power he’s shown is a player you can really get excited about.
What to work on:Â
Because he’s already 6-foot-2 and 205 pounds, there might not be a lot of projection in Hartshorn moving forward. While it’s not impossible he could grow an inch or two more, as of now, he’s kind of maxed out his body. That’s not inherently a bad thing—with many kids this age, you’re hoping they grow into that body—but it also means that he must maintain it. If he doesn’t work hard, what could be a slightly plus defensive right fielder can turn into a first baseman or a DH very quickly. It also means there’s less to dream on, but with his current pop, that’s easily forgiven.Â
Another thing; the bumps and bruises he’s suffered shouldn’t be entirely ignored. With back and elbow issues on the injury ledger already, it’s important that the team do everything to ensure that those do not become chronic, nagging and recurring. It could mean a little extra load management, or a different workout regimen, or teaching Hartshorn simply that it’s okay to take a game off through an ailment. Â
And while it’s less “something to work on” and more “just the truth of the matter,” Hartshorn is a prep player; he’s very far away. There’s a lot of potential here, but the only at-bats he’s taken in pro games have come this spring, and it’s only been a few at the back end of Cactus League contests. Patience is key. We may find that he struggles against a certain type of pitch more than others, or that mechanically, he needs to change some things (such as his big leg kick he flashes from time to time).
What’s next:Â
While many prep hitters need time in the Complex to work on adding bulk and size, Hartshorn is mostly filled out and should probably see Myrtle Beach pretty early in the year. Baseball America did note that his left-handed swing is a bit more raw, so the team may want to keep him in Arizona for a little bit of time just to work through refinement, but it’s pretty likely he’ll see a good chunk of time in Low-A.Â
The hope is that over the next few years, with a patient mindset, the Cubs can turn Hartshorn into an exciting, power-hitting corner outfielder from both sides of the plate. The athleticism is there today, and the arm strength should be a plus. If things go well, he could be MLB-ready in three years, putting him on track to make a debut by age 22. But not all things go the way you want to, and it could take time for the Cubs’ big investment to pay off. With a history of injury and his youth, it may take longer.Â
On the other hand, it does feel notable that he’s been in three Cactus League games, including playing a few innings of the team’s visit to the Brewers Wednesday. For a teenager who wasn’t a top pick to play big-league games the following spring speaks to the organization’s faith in his polish. On Wednesday, he hit the only pitch he saw hard in the air, flying out to deep right field on a cutter from Brewers lefty Shane Drohan—who’s eight years his senior and on the cusp of the majors.
Regardless, worrying about his MLB timeline right now feels like putting the cart before the horse. A successful 2026 will see Hartshorn spend his time in Myrtle Beach. Luckily for the Cubs’ newest addition, the Cubs have moved the fences in at Myrtle Beach this season by 10 feet, which should make hitting in the Low-A affiliate of the team a bit easier. Here’s hoping he can take advantage of the new, shorter porches.Â
