Diamondbacks Acquire Nolan Arenado From Cardinals in Low-Cost Deal

Arizona takes on about $11 million over two years with St. Louis sending $31 million in the deal.

Overview

  • Arenado waived his no-trade clause to finalize the move and is expected to be Arizona’s primary third baseman.
  • St. Louis received right-hander Jack Martinez, a 22-year-old eighth-round pick who struck out 110 in 77 1/3 innings at Arizona State last season.
  • Arenado is owed roughly $42 million through 2027, with Arizona responsible for $5 million in 2026 and $6 million in 2027 under the reported terms.
  • The trade ends the Cardinals’ year-plus effort to move Arenado as they reshape the roster under Chaim Bloom after earlier deals involving Sonny Gray and Willson Contreras.
  • Arenado, 34, remains an elite defender but is coming off a 2025 season marred by injuries and offensive decline (.237/.289/.377, 12 HR in 107 games).
