Diamondbacks Minor-League Infielders Trey Mancini, Nicky Lopez Opt Out Contracts

Arizona Diamondbacks minor league infielders Trey Mancini and Nicky Lopez have both opted out of their contracts in 2025 to explore free agency. Mancini, who has battled back from colon cancer and showed strong minor league performance with a .308/.373/.522 slash line, was released despite hitting .440 in spring training, largely due to positional constraints at first base with the Diamondbacks. Lopez, a defensive-minded utility player known more for his glove than his bat, hit .267/.303/.317 in Triple-A but struggled offensively during brief major league stints with multiple teams this year. Despite Lopez's solid defensive reputation and versatility across infield and outfield positions, his offensive production has been below average post-2021, leading the Diamondbacks to release him following his opt-out. Both players are expected to seek opportunities with other clubs, with Mancini praised by teammates as deserving another major league chance and Lopez likely looking for a role that values his defensive skills. The Diamondbacks' organizational depth and roster decisions have influenced these departures as they balance developing younger talent.
