Who won the Josh Naylor trade between the Arizona Diamondbacks and Seattle Mariners? Check out early grades to Josh Naylor trade on July 24, 2025.

Will Eugenio Suarez return to Seattle is one of the biggest questions as July 31 nears, and Buster Olney made his prediction on the latest 'Refuse to Lose' podcast.

Though the move is a position upgrade for Seattle, it isn’t ideal for Naylor’s fantasy value — he was hitting .324 with five homers, 36 RBIs and a .855 OPS at Chase Field. Since 2021, Naylor hit a homer roughly once every 24 at-bats — including a career-high 31 last year with Cleveland when he hit one every 18 at-bats.
