Anthony Eyanson Bio, Age, Height, Family, Career & Red Sox Prospect Ranking

Anthony Eyanson is one of the fastest-rising pitching prospects in Major League Baseball, currently ranked as the No. 2 prospect in the Boston Red Sox organization and turning heads across the minor leagues with a fastball that touches 100 mph. At just 21 years old, the right-handed pitcher has already overcome a life-threatening childhood illness, won a College World Series championship with LSU, and signed a $1.75 million contract—nearly double his draft slot value. From the baseball diamonds of Lakewood, California, to the Double-A Portland Sea Dogs, Eyanson’s journey is as much about resilience as it is about raw talent.

Quick Facts

Early Life & Education

Birth and Family Background

Anthony Scott Eyanson was born on October 9, 2004, in Long Beach, California, and raised in nearby Lakewood, a suburban city in Los Angeles County. He is the son of Jeff Eyanson, a professor, and Kristen Eyanson, who works at a chiropractic office.

Anthony grew up in a large, tight-knit family as one of six siblings—with three brothers (Blake, Joseph, and Andrew) and two sisters (Alexandria and Madyson).

The Achalasia Battle

Before Anthony ever stepped on a mound, he faced a life-threatening health crisis. As a child, he was diagnosed with achalasia—a rare esophageal disorder that prevents food from passing into the stomach. The condition is typically seen in adults aged 25 to 60 and affects less than 5% of children under 16.

The disease caused Anthony to plummet from 107 pounds to just 75 pounds—so emaciated that his mother could see his bones through his skin. He had to carry a container to spit into due to excessive salivation and was eventually rushed to Long Beach Memorial Hospital, where he was admitted for 15 days.

After undergoing a Heller Myotomy surgery, Anthony began his recovery. The experience, while harrowing, forged the mental toughness that would later define his athletic career.

High School: Lakewood Lancers

Eyanson attended Lakewood High School in Lakewood, California, graduating in 2022. He was a standout two-sport athlete, excelling in both baseball and football.

He also played for the Cotuit Kettleers in the prestigious Cape Cod Baseball League during the summer of 2024, and was selected to the USA Baseball Collegiate National Team for the International Friendship Series.

Louisiana State University (2025):

Seeking a bigger stage, Eyanson transferred to LSU for his junior season. He immediately became the Tigers’ Saturday starter—pitching behind 2025 No. 3 overall draft pick Kade Anderson—and delivered a breakout season that put him on every MLB scout’s radar.
