School: Oregon State Drafted/Committed: D-backs ’22 (18)

BA Grade: 60/High

Arquette became a premium transfer portal talent after a strong 2024 season at Washington where he hit .325/.384/.574 with 12 home runs, 14 doubles, a 17.5% strikeout rate and a 7.4% walk rate. Arquette took his talents to Oregon State for his 2025 draft campaign, where he slid from second base to shortstop for one of the nation’s top programs. Arquette has a major league body at 6-foot-5, 220 pounds and finished the season as a .354/.461/.654 hitter with a career-best 19 home runs and a career-low 16.5% strikeout rate. Arquette is a free and easy righthanded swinger whose above-average bat speed from his strong frame leads to comfortably plus raw power. He has the ability to drive the baseball to all fields and has always shown impressive pull-side power that has come with its share of swing-and-miss tendencies. Arquette did a nice job improving his approach in 2025 and demonstrated improved plate discipline that led to a 12.6% walk rate—the best mark he’s had in a complete college season. Arquette moves well for his size, but he’s more of a solid runner underway and has never been much of a base-stealing threat. He’s more likely to slow down in the future as he continues to add mass to his hulking frame. Defensively, Arquette has shown an ability to handle shortstop and potentially stick there. He has a plus, accurate arm that fits nicely on the left side of the infield, where he prefers to throw from a lower slot and has reliable hands. He has experience at second, but might profile best as a slugging third baseman if he needs to move. Viewed by many as the top college bat in the class, Arquette should be a slam dunk top-10 pick.

Track Record: Arquette broke out in 2024 at Washington, where he hit .325/.384/.574 with 12 home runs. He then transferred to Oregon State in 2025, shifted from second base to shortstop and elevated his game further by slashing .354/.461/.654 with 19 home runs. The Marlins drafted him seventh overall and signed him for a slot value bonus of $7,149,900.

Scouting Report: At 6-foot-5 and 220 pounds, Arquette looks the part of a modern slugger. His free and easy righthanded swing generates above-average bat speed and plus raw power, allowing him to drive the ball to all fields while punishing mistakes to his pull side. Though swing-and-miss and chase tendencies have accompanied that pop, he refined his approach in 2025, showing improved plate discipline and producing a thunderous 93.5 mph average exit velocity with a 59% hard-hit rate. At times, he over-corrected—his 60% zone-swing rate reflected a bit of hesitation—but the overall approach was more measured and mature. Arquette moves well for his size, grading as an average runner once underway. He’s never been a true basestealing threat, yet he matched his college high with seven steals in 27 games at High-A Beloit to align with the Marlins’ emphasis on basepath aggression. Defensively, he’s shown enough fluidity and arm strength to stick at shortstop, with above-average instincts, reliable hands and a plus, accurate arm from a lower slot. His physicality and offensive profile could ultimately fit at third base if a move becomes necessary.

The Future: Arquette’s combination of body control and powerful frame made him one of few sure-thing middle infielders in a 2025 draft class thin on them. He has the bat, arm strength and internal clock to remain at a premium position and should at least reach the upper minors in 2026.

Following a 2023 freshman season that saw him hit five home runs in just 15 games, Arquette thrived in 2024 in an everyday role with Washington where he hit .325/.384/.574 with 14 doubles, 12 home runs and 36 RBIs. The 6-foot-4 middle infielder then carried over his success the summer where he hit .291/.357/.437 with three home runs and 21 RBIs in 29 games with Chatham. Arquette has a free and easy swing with bat speed that leads to huge raw power and the ability to drive the baseball with authority to all fields. After playing mostly second base with Washington, Arquette handled shortstop capably in the Cape Cod League—a position he hadn’t played regularly since 2022 in the West Coast League. Arquette transferred to Oregon State for the 2025 season and between his projectable frame, power and defensive profile has a chance to become a first-round pick.

The top prospect in Hawaii for the 2022 class, Arquette is a lean and projectable shortstop with a 6-foot-4, 192-pound frame and a defense-over-bat profile currently. Arquette has solid actions defensively with above-average arm strength and the ability to make highlight plays, with better range than his below-average straight line running ability might have you believe and plus arm strength. Some scouts believe his lack of footspeed and twitch will move him off the position to third base, while others think he has the instincts and athleticism (he’s also a talented basketball player) to stay there. Arquette has long levers, and his swing can get lengthy and steep at times. He has made some adjustments this spring, however, with a shorter and more direct bat path, and with plenty of room to add muscle to his frame he has a chance to grow into above-average or even plus raw power. He’s a projection offensive prospect whose hitting ability will be reliant on him gaining strength and improving his bat speed, but he does show enough contact ability now for average hit tool projections. Arquette is committed to Washington.
