The Mariners promoted Marte from Low-A Modesto to High-A Everett on Monday.
The top prospect in the lower levels of the Seattle system, Marte was handed the promotion after slashing .271/.368/.462 with 17 home runs, 23 stolen bases and a 22.2 percent strikeout rate over 478 plate appearances at Low-A. He'll likely finish the season at Everett and begin the 2022 campaign with the affiliate, but a hot September could put him in position for a quick call-up to Arkansas at some point next spring.
