All-Star first baseman Josh Naylor has arrived and is in the lineup to make his Seattle Mariners debut Friday night against the Los Angeles Angels.

Jerry Dipoto has a longstanding reputation for jump-starting the Trade Deadline market, and the Mariners’ president of baseball operations indeed sparked this year’s traction, with the first major domino falling to Seattle on Thursday night.

Josh Naylor is headed to the American League. The Diamondbacks’ first baseman is going to the Mariners in a trade on Thursday night, The Post’s Jon Heyman confirmed Minor league pitchers Ashton Izzi and Brandyn Garcia are headed back to Arizona.

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.

With a 55–48 record, the Mariners sit second in the AL West and currently hold a Wild Card spot. Their elite pitching staff, one of the league’s top rotations and bullpens, has carried them for much of the season. But offensively, the team has struggled, ranking near the bottom in key metrics.

The Seattle Mariners kicked off their trade deadline activity Thursday by acquiring a former All-Star from the Arizona Diamondbacks.

Seattle Mariners Executive Vice President & General Manager of Baseball Operations Justin Hollander announced today the Mariners have acquired infielder Josh Naylor from the Arizona Diamondbacks in exchange for left-handed pitcher Brandyn Garcia and minor league right-handed pitcher Ashton Izzi.
