1. Cole Young is the first prospect to keep
Cole Young is currently ranked as the Mariners number one prospect by MLB Pipeline and he showed out last season in Modesto and Everett. The 20-year-old hit 277/.399/.449 in over 600 plate appearances between his two minor league teams last year. He showed a good feel for hitting and he is arguably the best pure hitter the Mariners have in the minor leagues. He probably doesn't stick at shortstop, but I think he will be a plus defender at second with a good bat.
We won't know where he is assigned to start the season for several months, but I fully expect Young to see at least some time at Double-A Arkansas in 2024. I would not push him and send him to Triple-A Tacoma or the big leagues at all next year, he's not the type of prospect Julio Rodriguez was. But, in 2025 he could be the starting second baseman or maybe come up halfway through the season and be a big contributor on the infield for this team for the second half of the decade.
