Cubs’ Josiah Hartshorn cements himself in franchise lore with 20th Home Run

Chicago Cubs 2025 sixth round draft pick Josiah Hartshorn is having a breakout season. The 19 year old 1B/OF from Orange Lutheran High School has propelled up prospect rankings this year, including becoming the organization’s No.1 prospect and MLB Pipeline’s No.39.

This year, Hartshorn has dominated the Low-A and High-A ranks. As of August 24, he is slashing a combined .285/.404/.515 with an incredible 20 home runs, 99 RBI’s, 22 doubles, 12 stolen bases, and 76 walks to 92 strikeouts. His 99 RBI’s are currently the most of any player drafted last summer who made their professional debut in 2026.

Over the weekend, Hartshorn launched home run No. 20, which put him in some elite territory as a Cubs teenage minor league prospect.

Josiah Hartshorn becomes the first teenage prospect in 27 years to reach 20 home runs in a season

On Saturday, Hartshorn hit his 15th home run of the season with the South Bend Cubs, adding to the five he hit earlier this year with the Myrtle Beach Pelicans, where he spent just 39 games. That brings his season total to 20 home runs, making him the first Cubs teenage prospect since Corey Patterson in 1999 to reach the milestone.

Furthermore, Hartshorn’s 15 home runs with the South Bend Cubs have him tied with Jordan Nwogu and Yonathan Perlaza for the most in a single season by a South Bend player since 2015. If he can hit one more before the minor league season concludes on September 6, Hartshorn will become the new record holder.

At just 19 years old, Hartshorn is already putting his name alongside some of the more notable prospects in Cubs history. His 20 home runs are impressive on their own, but the fact that he has reached that mark while setting himself up to break South Bend’s single-season home run record makes his season even more notable. With several games still remaining, Hartshorn has a chance to add another chapter to what has quickly become a historic year.
