St. Louis Cardinals Trade Nolan Arenado for Jack Martinez

ST. LOUIS — The St. Louis Cardinals completed a trade with the Arizona Diamondbacks on Tuesday, acquiring right-handed pitcher Jack Martinez in exchange for third baseman Nolan Arenado and cash considerations.

Martinez, who played college baseball at Trinity University and the University of Louisiana, posted a 6-4 record with a 5.94 earned run average in 15 starts during the 2025 season with the Sun Devils. He struck out 110 batters over 77.1 innings pitched.

Arenado, who had been with the Cardinals since 2021, batted .237 last season with 95 hits in 401 at-bats.

“We are grateful for Nolan’s five years as a Cardinal, on and off the field — for his drive, his competitiveness, and for all of the memories he gave us,” Cardinals president of baseball operations Chaim Bloom said in a statement.

“As we continue to move forward, we are pleased to add another intriguing pitching prospect to our organization, and excited for the opportunity this move creates for a number of our players to step up and further establish themselves at the big league level.”
