Westfield High School in Virginia has had just one player get drafted and sign out of the school -- 2005 first-round pick Brandon Snyder, though big leaguer Justin Bour did go there before heading to George Mason University. Farmelo, who showed off his tools at events like the PDP League and East Coast Professional Showcase over the summer, has the chance to be the next.

Farmelo is a physical athlete with a lot of tools to like. He's a plus runner, which helps him on both sides of the ball, and has shown the ability to find the barrel consistently and drive the ball to all fields. There's plenty of bat speed, and he's quick to the ball, with more power to come as the 6-foot-2 left-handed hitter matures. 

A right-handed thrower, Farmelo has played shortstop for his high school in the past, but he spent all summer in the outfield and that could be a very good fit for him long-term. He has the speed and range to play center field, with the upside of being a dynamic up-the-middle presence. The biggest question facing teams might his commitment to the University of Virginia.

When Julio Rodríguez won American League Rookie of the Year Award honors in 2022, not only did it bring the hardware to the Mariners organization for the fifth time, they also received an extra pick in the 2023 Draft. That selection, No. 29 overall, was used on Farmelo, a super-toolsy Virginia high schooler who was headed to the University of Virginia until the Mariners swooped in and went over-slot to sign him for $3.2 million. He was making a very strong first impression during his pro debut with Single-A Modesto in 2024 when he tore his right ACL in June, ending his year after just 46 games.

Despite the injury, which should keep him out until around midseason in 2025, Farmelo opened a lot of eyes both within the organization and from other teams’ evaluators. His carrying tool was his potentially double-plus speed that allowed him to steal 18 bases in his abbreviated season, but now it remains to be seen if he gets all of that explosiveness back post injury. Using very unorthodox swing mechanics, Farmelo displayed an advanced approach, taking walks and making good swing decisions from the left side of the plate while showing he was already getting to some of his impressive raw power. The Mariners thought he was more power-over-hit when he first joined the organization, but there’s more confidence it’s leveled out a little.

Farmelo’s speed is an asset in the outfield as well, and he should be at least an above-average defender in center field for a long time. The track record for young players coming back from this injury is pretty good, and the Mariners are banking on Farmelo’s plus makeup for him to return to the emerging star he looked like before he went down.

A hugely welcome addition to the Mariners system thanks to the pick awarded as a result of Julio Rodriguez's Rookie of the Year Award, Farmelo blossomed on the Draft radar thanks to events such as the Major League Baseball's PDP League and the East Coast Professional showcase. Seattle signed Farmelo for well over slot value, at $3.2 million, to steer him away from his commitment to the University of Virginia, and he was among the three prep bats the club took within the top 30 overall picks that the club plans to build its long-term lineup around. He was off to a solid start to his first full season in 2024 when he tore his right ACL in June, ending his year.

Before the injury, Farmelo quickly drew attention for his plus-plus speed that's already been touted among the best in the organization. He also plays above-average outfield defense, which raises his floor in the context of being a Major League contributor. And with a sound hit tool that puts a disciplined premium on driving the ball to all fields, along with the potential to grow into power, his ceiling is also high. 

That said, his hitting profile is still very raw, with a swing that looks comparable to a pickle-ball serve that at times can be rigid and limit him from making adjustments throughout an at-bat. There are plenty of paths that the Mariners can take to hone him in this regard because the bat speed from the left side has 20-homer potential.

After showing off his tools on the summer showcase circuit at events like Major League Baseball's PDP League and the East Coast Professional showcase, Farmelo parlayed a strong senior season to become just the second player, after 2005 first-round pick Brandon Snyder, to get drafted and signed out of Westfield High School in Virginia. The Mariners used the pick they were awarded as a result of Julio Rodriguez's Rookie of the Year Award to take Farmelo, going over slot to sign him away from his commitment to the University of Virginia.
