With the seventh pick of the 2025 MLB Draft, the Miami Marlins selected Oregon State shortstop Aiva Arquette. The Marlins added one of the top position players in this draft class. Arquette is the #2 ranked prospect on our 2025 MLB Draft Big Board. 

“Awesome day for the Marlins,” Marlins director of amateur scouting Frankie Piliere said about their first-round selection. “We got the best position player in the draft class.” 

Aiva Arquette is a 6’5″, 220-pound shortstop out of Oregon State University. During the 2025 season, Arquette slashed .354/.461/.654 with 90 hits, 17 doubles, 19 home runs, 66 RBIs, and a 1.115 OPS. He was named Second Team All-American on D1 Baseball.

At the plate, Arquette has good swing mechanics with the ability to hit the ball to all fields. The Hawaiian native had adjustments to his swing to lift the ball more often with his pop. Arquette’s average air exit velocity was 96.8 mph with a max exit velocity of 112.9 mph. Defensively, Arquette projects as a third baseman with plus arm strength. 

“I might say he’s [Arquette] one of a kind,” said Piliere. “He’s a different kind of player, a 6’5″ right-handed-hitting shortstop. We think he has a chance to be a very special player.” 

The slot value for the seventh pick is $7,149,900.
