ARENADO TRADED TO SEATTLE, CARDINALS PROMOTE TOP PROSPECT
St. Louis — Derrick Goold | April 4, 2025

ST LOUIS - Just hours before opening their weekend series against the Boston Red Sox, the St. Louis Cardinals announced a trade that everyone knew was coming, sending veteran third baseman Nolan Arenado to the Seattle Mariners in exchange for switch-pitching right-hander Jurrangelo Cijntje and power-hitting outfielder Lazaro Montes.
The move signals both a commitment to the Cardinals’ youth movement and a willingness to reshape the roster around emerging stars. As part of the transaction, St. Louis assigned both Cijntje and Montes to Triple-A Memphis, while promoting top prospect JJ Wetherholt to the major-league roster.
Arenado, now 35, leaves St. Louis after four full seasons and the early portion of a fifth, delivering the elite defense and middle-order stability he was known for throughout his career. Arenado’s career totals stood at:
1,622 hits
341 home runs
1,120 RBI
.287 batting average
10 Gold Gloves
6 All-Star selections
Though his power has declined in recent seasons, Arenado remained a respected clubhouse presence and one of baseball’s most polished defenders at the hot corner.
He now joins a Mariners club looking to add veteran leadership and right-handed stability to a lineup chasing the top of the AL West.
What the Cardinals Get Back
Jurrangelo Cijntje — RHP/LHP, 21
One of baseball’s most unique pitching talents, Cijntje throws from both sides and features mid-90s velocity right-handed and a more deceptive, slider-heavy mix left-handed. Seattle fast-tracked him to Triple-A last season, and the Cardinals will continue his development in Memphis with the expectation he could debut sometime this season.
Lazaro Montes — OF, 20
Few prospects in the minors can match Montes’ raw power. The 6'4" left-handed slugger hit 30+ homers across two levels last season and gives St. Louis a long-term middle-order candidate. His strikeout rate remains high, but the Cardinals believe his approach has matured enough to take the next developmental step in Triple-A.
The Wetherholt Era Begins
St. Louis wasted no time filling the void on the MLB roster, announcing that JJ Wetherholt, the club’s top infield prospect, has been promoted ahead of tonight’s opener in Boston. The 2024 first-round pick impressed throughout the spring, showing elite contact skills, speed, and defensive versatility. He is expected to split time between second and third base.
