Diego Castillo

Castillo was scooped up by Arizona when Pittsburgh designated him for assignment prior to 2023 spring training and spent all but one day at Triple-A Reno. He appeared to change his approach with the new organization, increasing his walk rate to 17.6 BB% and posting a .431 on-base percentage, while playing left field, second base, shortstop and third base. Overall, it was his best year in the minors - MiLB.com's Organizational All-Star rankings rated him the system's best second baseman - but it wasn't enough for the 26-year-old to hold onto a spot on the 40-man roster. He was jettisoned to make room for Lourdes Gurriel, who re-signed with Arizona. A return to Reno had been expected, but Castillo was claimed off waivers by the Mets. He's another in a string of fringe additions New York made during the offseason. He could fill an infield depth role behind Pete Alonso, Jeff McNeil and Francisco Lindor. Read Past Outlooks
