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.

The Seattle Mariners have acquired lefty-batting first baseman Josh Naylor from the Diamondbacks. Arizona gets left-hander Brandyn Garcia and right-hander Ashton Izzi back in the deal. The Diamondbacks announced the trade on Thursday evening.
