The Seattle Mariners are focusing on bolstering their offense this offseason to complement their strong pitching staff, which includes standout players like Luis Castillo and George Kirby. They are exploring trades for second baseman Nico Hoerner of the Cubs and first baseman Josh Naylor of the Guardians, with reports suggesting they may need to part with key prospects to secure these deals. Additionally, former Mariners such as Carlos Santana and Paul Sewald are potential targets for re-signing as the team seeks affordable veterans to enhance their lineup. Meanwhile, the Arizona Diamondbacks are also strategizing for the offseason, aiming to improve their pitching without sacrificing their recently developed high-scoring offense. The Diamondbacks' budget constraints are forcing them to consider trades, particularly regarding Jordan Montgomery's contract. Both teams emphasize the importance of smart roster decisions and fan engagement as they look to improve their competitiveness in the upcoming season.
