Aiva Arquette

22-Year-Old ShortstopSS

2026 Fantasy Outlook
Arquette, who the Marlins selected with the No. 7 overall pick in 2025, will likely have a long career as an everyday player but he's more floor than ceiling in fantasy. A 6-foot-5 infielder from Hawaii, Arquette made noise as a sophomore at Washington (.959 OPS) and held his own with a wood bat in the Cape Cod League in 2024 (.793 OPS) before hitting his way into the top 10 of the draft after transferring to Oregon State. Arquette slashed .353/.462/.647 with 18 home runs, seven steals and a 50:39 K:BB in 64 games as a junior while playing all his games at shortstop -- he saw time at third base and second base with Washington and on the Cape. Still, he didn't do his damage in the SEC or ACC and was good, not great (23.9 K%), during his toughest test on the Cape. He was one of a select few college draftees to get sent to High-A, where he held his own with a .242/.350/.323 slash line, one home run, seven steals, a 14.5 percent walk rate and a 23.1 percent strikeout rate in 27 games, good for a 103 wRC+. If Arquette can maintain his fringe-average speed he could stick at shortstop, otherwise he'd fit well at third base. It would be a red flag if he's struggling to handle Double-A and Triple-A in 2026. Read Past Outlooks

The Marlins have selected Arquette with the seventh overall pick in the 2025 First-Year Player Draft.
Analysis
A 6-foot-5 infielder from Hawaii, Arquette made noise as a sophomore at Washington (.959 OPS) and held his own with a wood bat in the Cape Cod League last summer (.793 OPS) before hitting his way into the top 10 of the draft this year after transferring to Oregon State. Arquette slashed .353/.462/.647 with 18 home runs, seven steals and a 50:39 K:BB in 64 games as a junior while playing all his games at shortstop -- he saw time at third base and second base with Washington and on the Cape. Still, he didn't do his damage in the SEC or ACC and was good, not great (23.9 K%), during his toughest test on the Cape. Arquette's combination of capable defense at a premium position and the ability to hit for average and power stand out in a weak crop of college hitters, but he doesn't have a particularly high fantasy ceiling relative to the typical top college hitter in a class.
