Scouting Report

Scouting grades: Hit: 50 | Power: 60 | Run: 50 | Arm: 60 | Field: 50 | Overall: 55

Hawaii's top prep prospect in 2022, Arquette turned down the Diamondbacks as an 18th-rounder to attend college at Washington. After two seasons with the Huskies and an all-star summer in the Cape Cod League, he transferred to Oregon State and became the consensus best college position player in the 2025 Draft. He slashed .354/.461/.654 with 19 homers before signing with the Marlins for $7,149,900 as the No. 7 overall pick.

The 6-foot-5, 220-pound Arquette is bigger than most shortstops and hits the ball much harder than most players at his position. He combines a quick right-handed swing and strength with the propensity to drive balls in the air, giving him 30-homer potential. He has a reasonably disciplined approach but misses more fastballs than he should, including heaters over the plate.

Arquette moves well for his size and is an average runner but not much of a threat to steal. Primarily a second baseman at Washington, he looked surprisingly smooth for a 6-foot-5 shortstop this spring. He features plus arm strength and the ability to make throws from a variety of angles, and he may be able to remain at short in pro ball.

There have been a grand total of eight high school position players from Hawaii to be taken in the top 10 rounds of the Draft since the turn of the century, with just one so far, Isiah Kiner-Falefa, to post a positive WAR. Arquette, an infielder like Kiner-Falefa, hopes to be the next after impressing scouts at events like the Area Code Games last summer and Perfect Game's WWBA World Championship in the fall.

An excellent athlete who is also a basketball standout, Arquette has added nearly nearly 25 pounds of muscle to his 6-foot-4 frame since his sophomore year of high school. He's starting to figure things out at the plate and has the chance to hit from the right side of the plate, with plenty of raw power to tap into as he continues to physically mature.

Arquette has solid defensive actions, with good hands and a strong arm. Because of his size and lack of pure foot speed, most see a move to third in his future, with a chance to grow into an offensive profile that fits at the hot corner. A team that believes in the Washington recruit's offensive upside could take him at some point on Day 2 and give him the chance to stick at short and live up to the lofty comparisons he gets locally to another tall shortstop who loved to play basketball: Cal Ripken Jr.

As a Hawaiian prep standout, Arquette's athleticism -- he also played basketball in high school -- stood out on the summer showcase circuit, and he landed in MLB Pipeline’s Top 250. The D-backs took him in Round 18 of the 2022 Draft, but he headed to the University of Washington. After playing sparingly with the Huskies as a freshman, he earned all-Pac 12 honors after finishing with a .959 OPS as a sophomore. Over the summer, the infielder entered the transfer portal, played well in the Cape Cod League and transferred to Oregon State for his junior season, where he has been one of the most consistent college performers.

Scouts see the 6-foot-5, 220-pound Arquette as the best college player in the Pacific Northwest this year -- and one of the best college hitters in the country. While minor wrist surgery cut into his fall with his new school, the right-handed hitter showed he has easy raw power to tap into, with more to come, and he's used it in games consistently this spring. He routinely barrels the ball with good bat speed and a fluid swing, giving him the chance to be an above-average hitter with above-average power, and he could hit 20-25 homers annually as a big leaguer.

While Arquette is an average runner and played second base at Washington, he showed on the Cape that he should have the chops to play shortstop long-term, with easy actions, soft hands and more than enough arm with carry at every angle across the diamond. College bats with pop at a premium position are always a hot commodity, so Arquette should get plenty of attention in the first round.
