Mariners acquire 1B Josh Naylor from Diamondbacks

The Seattle Mariners acquired first baseman Josh Naylor from the Arizona Diamondbacks on Thursday in exchange for left-handed pitcher Brandyn Garcia and right-hander Ashton Izzi.

The move gives Seattle an offensive upgrade at first base, where incumbent Luke Raley was hitting .220 with four homers and 18 RBIs.

After being traded from the Cleveland Guardians during the offseason with one year left on his contract, Naylor batted .292 with 11 home runs and 59 RBIs in 93 games for the Diamondbacks.

"We are thrilled to add Josh as we make a push for the postseason," Seattle general manager Justin Hollander said in a statement. "Josh's ability to hit for both average and power is unique and we are excited to not face him anymore."

Naylor is a career .267 hitter with 95 homers and 402 RBIs across seven major league seasons, including stops with the San Diego Padres (2019-20), Cleveland (2020-24) and Arizona (2025).

Garcia, Seattle's No. 13 overall prospect, per MLB Pipeline, made his big-league debut on Monday. In two games as a reliever for the Mariners, he logged two innings, giving up two runs (one earned) on four hits with a strikeout and three walks.

Garcia, 25, made a combined 32 appearances in Double-A and Triple-A this year, going 5-4 with five saves and a 3.51 ERA.

Izzi, the Mariners' 16th-ranked prospect per MLB Pipeline, had spent the season with high Class-A Everett. In 12 games, all starts, the 21-year-old went 2-4 with a 5.51 ERA and 54 strikeouts over 47 1/3 innings.
