Scouting Report

2026

Scouting grades: Hit: 45 | Power: 40 | Run: 40 | Arm: 55 | Field: 50 | Overall: 40

The A's got a close look at Diaz as a local amateur when he played at Acalanes HS (Calif.) and liked what they saw back then, leading to his selection by the club years later coming out of Vanderbilt in the eighth round of the 2024 MLB Draft. He's been on a steady climb through the system since joining the organization. Jumping from Single-A Stockton to High-A Lansing in 2025, he made another leap early on in '26 with a promotion from High-A to Double-A Midland after a strong performance in first 29 games with the Lugnuts.

Diaz stands out at the plate for his impressive bat-to-ball skills and overall patience in the batter's box. That has translated to a low strikeout rate and solid on-base numbers early in his pro career. The contact skills help mitigate the lack of power he's shown thus far, though he has increased his frequency of extra-base hits this season, which gives some hope that there is some more pop in that bat to unlock.

The A's raised some eyebrows when they decided to utilize Diaz, primarily a third baseman in college, as a catcher, a position he hadn't played since high school. So far, that decision is looking great as he's demonstrated clean mechanics behind the dish along with a strong arm and ability to control the run game. Still showing off his versatility by getting some time at third, second and even some first base, Diaz is quickly emerging as an intriguing super-utility player with enough tools to eventually make a big league impact.

Scouting grades: Hit: 55 | Power: 45 | Run: 50 | Arm: 50 | Field: 50 | Overall: 50

Perhaps the best player from Northern California in this Draft class, Diaz has been on the national radar for some time now, playing for USA Baseball’s national 12U team back in 2015 and the 15-and-under team in both 2017 and 2018. He had a solid showcase showing in 2020, including being named to the all-tournament team at Perfect Game’s World Wood Bat Association World Championship.

While Diaz doesn’t have one tool that jumps off the page, he does a lot of things really well. The right-handed hitter has gotten stronger and does have the chance to eventually be a better than average hitter. He’s shown the ability to make hard contact and send line drives to all fields, with that added strength sure to help him get to more power in the future. He’s an average runner who has good instincts.

Those instincts have helped him on the defensive end as he’s shown an ability to play shortstop in high school despite that lack of first-step quickness. He has decent hands and an average arm, with many thinking that, plus the lack of range, will necessitate a move in the future. He’s offered scouts a new look by catching this spring and has shown a solid release and good hands behind the dish. Whether that addition to his profile is enough to sign him away from his Vanderbilt commitment remains to be seen.
