The New York Mets have made waves with the recent acquisition of left-handed pitcher Jose Castillo from the Arizona Diamondbacks. Fans and analysts alike wonder what this trade means for both teams as Castillo brings his experience and talent to New York.

Mets Trade for Jose Castillo: The Deal

On Thursday night, the Mets completed a deal with the Arizona Diamondbacks. They acquired Jose Castillo for cash considerations. According to Yahoo Sports, Castillo, who is 29, had pitched five games for the Diamondbacks this season. While his 11.37 ERA during those outings raised eyebrows, his prior track record shows signs of promise.

Castillo was designated for assignment after his latest appearance on May 11, paving the way for this trade. It's worth noting that his best major league season came in 2018, when he posted a 3.29 ERA and an impressive 0.91 WHIP in 37 games for the San Diego Padres.

A Look at Castillo’s Recent Performance

Castillo’s 2025 season with the Diamondbacks was a rollercoaster. His stint in the minors, pitching for the Reno Aces, saw him excel with a remarkable 1.69 ERA over 5.1 innings, no walks, and seven strikeouts. However, once he joined the big league roster, consistency became an issue. As detailed by Sports Illustrated’s Diamondbacks coverage, Castillo struggled in the majors. He gave up home runs in his debut and was hit hard by top-tier teams like the Dodgers and Mets themselves.

Injuries have also hampered his progress. Castillo missed all of 2024 due to ACL recovery and had previously dealt with various setbacks. Still, the Mets see potential in his left-handed arm, especially considering their current bullpen needs.

What the Trade Means for the Mets

Bringing Jose Castillo into the Mets’ bullpen provides much-needed left-hand depth. With other relievers like Kevin Herget being designated for assignment to make room on the roster, the Mets are hopeful Castillo can regain his 2018 form. Given his track record and flashes of excellence, he represents a low-risk, high-reward option for New York.
