This article was originally published on www.si.com/mlb/mariners as ESPN MLB Insider Gives Bold Take on Seattle Mariners as Trade Deadline Nears. With the MLB Trade Deadline coming up on July 31, ESPN MLB Insider Jeff Passan described the Seattle Mariners as "all-in."

The latest turn in the MLB trade market saw the Yankees get a third baseman, which could help the Seattle Mariners' push to land Eugenio Suárez.

The MLB trade deadline isn't until July 31 at 6 p.m. ET, but the Arizona Diamondbacks and Seattle Mariners reportedly didn't waste much time making the first major swap of the season.

While Naylor may not be the impact bat that the Mariners had been shopping for, he does have plenty of power. He hit 31 homers as part of an All-Star season for Cleveland in 2024 and should provide more power for a Marines lineup that could use a boost.

Don't think that the Seattle Mariners' trade Thursday night for one Arizona Diamondbacks All-Star rules them out for acquiring another.

"The Seattle Mariners are acquiring first baseman Josh Naylor from the Arizona Diamondbacks, sources tell ESPN," Passan tweeted. Naylor was an All-Star last year with the Cleveland Guardians, who traded him to Arizona in the offseason. In exchange for Naylor, Seattle is sending pitching prospects Brandyn Garcia and Ashton Izzi back to Arizona.

The Seattle Mariners have reportedly acquired an All-Star slugger in a trade this week with the Arizona Diamondbacks.
