As of late 2025, the right-handed pitcher (RHP) and shortstop (SS) is known for his powerful arm and his highly-publicized commitment to LSU, but a persistent and unverified rumor continues to follow him: the claim that he was expelled from high school. This article investigates the facts, the forum chatter, and the documented pattern of movement that has defined his path from Hebron High School to multiple NCAA Division I programs. The keyword "MJ Seo expelled from high school" is a search term rooted in online speculation, specifically tied to his early departure from the Hebron High School baseball team during his senior year. While no official or mainstream news source has ever confirmed an expulsion, the incident marked the beginning of a complex and turbulent career path that has seen the highly-touted prospect bounce between three major college programs in quick succession, fueling further curiosity about the stability of his journey.

Seo's high school career at Hebron was stellar, earning him a spot on the 2023 Dallas/Fort Worth All-Area First Team. He was a legitimate two-way prospect, showing a fastball velocity up to 94 mph and strong defensive skills at shortstop. His commitment to the powerhouse LSU Tigers baseball program was a major recruiting win, positioning him for a potential future in the MLB Draft.

The Unconfirmed High School Expulsion Rumor

The root of the "expelled" keyword stems from an incident during Seo's final year at Hebron High School. Sometime during the 2023 season, the star player abruptly left the high school baseball team. This unexpected exit from a high-profile player who was an LSU signee immediately sparked intense speculation among fans and recruiters.

What the Online Chatter Says

On various recruiting forums and fan message boards, the question of "Why did MJ Seo leave Hebron?" quickly morphed into the unverified claim of an "expulsion." These online discussions often lack verifiable sources, but they highlight the intense curiosity surrounding the situation. The key facts are:

• Early Departure: Seo left the Hebron team before the end of his senior season.
• Lack of Official Statement: Neither Hebron High School nor the Seo family released a public statement clarifying the exact reason for the departure.
• The Rumor: In the absence of official information, the most sensational claim—that of an expulsion—took hold in the online community.

It is critical to understand that the term "expelled" remains an unconfirmed rumor. It is plausible that the departure was due to an internal team disciplinary issue, a disagreement with the coaching staff, or a mutual decision to focus on his preparation for the LSU program. However, the lack of transparency is what allowed the more dramatic, negative narrative to dominate search interest. Addressing the keyword responsibly means pointing to the documented *fact* of the early exit as the source of the *unconfirmed rumor* of expulsion.

A Pattern of Movement: The College Transfer History

While the high school incident remains shrouded in rumor, MJ Seo’s college career provides a documented pattern of instability that mirrors the curiosity surrounding his high school exit. His journey through the NCAA Transfer Portal is a clear, verifiable story of a highly-rated player struggling to find a long-term home.

1. The LSU Tigers (2024)

Seo enrolled at Louisiana State University, one of the premier college baseball programs in the nation. The expectation was that he would be a key part of the Tigers' future rotation. However, his time in Baton Rouge was short-lived. * He redshirted his freshman season in 2024, meaning he did not play in any games. * At the conclusion of the season, Seo entered the NCAA Transfer Portal, departing the LSU program after only one year.

2. The Wichita State Shockers (2025)

Following his departure from LSU, Seo transferred to Wichita State University, joining the Shockers. This move was seen as an opportunity for a fresh start and a chance to compete for playing time. * His time at Wichita State was even briefer. He pitched in only one game, retiring a single batter, before deciding to transfer again. * His former Hebron High School teammates, Lane Haworth and Tyler Dobbs, were also at Wichita State, which suggests an attempt to find comfort and stability with familiar faces, though it ultimately did not last.

3. The CSUN Matadors (2026)

For the 2026 season, MJ Seo has transferred to Cal State Northridge (CSUN), where he is listed as a Redshirt Sophomore on the Matadors' roster. This is his third Division I program in three years. This documented history of transfers—moving from LSU to Wichita State, and then to CSUN—reinforces the narrative of a talented player struggling to settle into a program. This college instability, while not directly related to the high school rumor, feeds the overall curiosity about the player’s journey and his ability to remain with a team.

Topical Authority: The Impact of Instability on a Prospect’s Value

In the world of baseball recruiting and the MLB Draft, stability and consistency are highly valued. MJ Seo’s career, marked by the unverified high school incident and the confirmed college transfer history, presents a unique case study in how off-field or team-related issues can affect a prospect's value. * Recruiting Risk: Coaches and scouts often view a pattern of transfers or unexplained departures as a potential "red flag," regardless of the player's on-field talent. * NCAA Transfer Portal: Seo's multiple entries into the Transfer Portal highlight the fluid and often chaotic nature of modern college athletics, where players seek the best fit for immediate playing time and development. * Focus on CSUN: His current tenure at Cal State Northridge represents a crucial opportunity to stabilize his career. To regain the high-level prospect status he held in high school, he will need to establish himself as a consistent and reliable pitcher for the Matadors. The mystery surrounding the early exit from Hebron High School will likely continue to be a topic of discussion among baseball fans. However, the true story of MJ Seo's career lies in his ongoing attempt to translate his massive potential into sustained success at the collegiate level, a journey that has been anything but conventional.
