Diamondbacks Make Waves with Matt O’Neill Signing
The Arizona Diamondbacks have generated excitement this offseason by signing veteran catcher Matt O’Neill, as reported by MLB insider Joel Sherman. This deal, which is a minor league contract, comes with an invite to the big league’s Spring Training, providing O’Neill an opportunity to showcase his skills at the highest level.
A New Addition to the Catching Roster
O’Neill becomes the second catcher to join the Diamondbacks this winter, following the earlier signing of veteran minor-leaguer Aramis Garcia, who is returning to the organization. This dual acquisition signals Arizona’s commitment to strengthening their catching depth as they prepare for the upcoming season.

Hailing from Morristown, New Jersey, O’Neill brings a wealth of experience, having spent significant time in the New York Mets’ farm system from 2019 to 2025.
