2025 MLB Draft Profile: Gavin Fien

The Miami Marlins have been linked to high school hitting prospects with their first-round pick heading into the 2025 MLB Draft. Gavin Fien is another candidate for the Fish to consider with the seventh overall pick.

Overview

Position: 3B

Height: 6’3″

Weight: 200 pounds

School: Great Oak HS (CA)

Commitment: Texas

FOF Big Board Rank: 10th

Gavin Fien is a 6’3”, 200-pound third baseman who plays at Great Oaks High School in Temecula, California. Fien is a well-rounded prospect with plus hitting and defensive tools. Fien also had a huge summer—playing for Team USA and winning Game MVP at the MLB High School All-American Game—but he struggled during his senior season.

On Perfect Game, Fien is an elite high school recruit in one of the most talent-rich areas in the country. Fien is the ninth-ranked prospect and #1 third baseman in the country. He’s the third-ranked prospect out of the Golden State. He was also selected to play in the Perfect Game All-American Classic.

Fien is a right-handed hitter with an unorthodox batting stance. That didn’t affect his timing at the plate in the fall. The issues with timing that showed up in the spring should be correctable. Fien has a fluid swing with nice raw power potential. He still has some room to fill in his frame and should be able to add more power as he physically matures.

Defensively, Fien is a very sound third baseman with good mechanics and one of the top arms at the hot corner. Fien is also a good athlete and could play some right field with his plus arm strength. According to Perfect Game, he ran a 6.86 60-yard dash and threw 94 mph from the infield and 98 mph from the outfield.

Strengths

• Plus hit tool
• Raw power potential
• Good athlete
• Plus arm strength
• Defensive versatility
• Has hit well with a wood bat against tough competition

Weaknesses

• Struggled a bit in his senior season
• Needs to improve timing with his stance

Pro Comparison: Ian Stewart

Projection: Top 20 pick

Bottom Line

Gavin Fien is a well-rounded prospect who could develop into one of the best hitters in this draft class. Fien isn’t a finished product, but his hitting ability and arm strength are very intriguing. The Marlins could be the team to draft him if they have confidence in their minor league coaching staff to help him with fixing his timing issues and filling in his large frame.
