Luis Castillo allowed a run in seven innings, Josh Naylor hit his first home run for the Mariners and Seattle beat the Athletics 3-1.

The Arizona Diamondbacks have made a big move this month, but they could continue to make more moves as the trade deadline draws closer.

In a wide-open American League, the Mariners will have as good a chance as anyone to make a deep postseason run, and Naylor could be a big part of that. He’s played in three postseasons and is known for hitting clutch home runs.

Naylor signed for $10.9 million with Arizona after the trade. He was not eligible for free agency. The Guardians signed Carlos Santana for $12 million to replace Naylor at first base. Cleveland believed it was wiser to trade Naylor in December than wait to do it in the middle of the season.

Pressure is a privilege in the eyes of new Seattle Mariners slugger Josh Naylor. The 28-year-old first baseman is looking forward to the opportunity to bat cleanup in his first game with Seattle against the Los Angeles Angels on Friday night.

The Boston Red Sox will be targeting a first baseman at the 2025 MLB trade deadline, this prediction lands a former All-Star to fill the void.
