The Seattle Mariners used a scorching final few weeks of the 2025 regular season to capture the AL West crown. Current M's first baseman Josh Naylor was a major trade deadline pickup, as the Mariners front office beat out the Cincinnati Reds. “The Cincinnati Reds were close to acquiring Diamondbacks first baseman Josh Naylor at the trade deadline before he went to the Seattle Mariners and became instrumental in their resurgence. The Mariners will make every attempt to sign Naylor as a free agent this winter.”Resigning Naylor makes sense. Will Mariners or Reds sign Josh Naylor this winter?
