Diamondbacks' Jordan Montgomery: Slated for Tommy John surgery

Montgomery will undergo Tommy John surgery next week, Nick Piecoro of The Arizona Republic reports.

Montgomery had seemed like a good bet to be traded eventually, but that's not going to happen now. The surgery ends a nightmarish stint in Arizona, as Montgomery posted a 6.23 ERA last season after signing late and never getting on track. He will be a free agent this winter and likely miss at least the first couple months of the 2026 season.
