View Draft Report
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.

School: Oregon State Drafted/Committed: D-backs ’22 (18)
Age At Draft: 21.8
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.

Age At Draft: 21.8
BA Grade/Risk: 50/High
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.
