The Mariners are planning to select right-hander Prelander Berroa onto their 40-man roster, president of baseball operations Jerry Dipoto tells reporters (including Ryan Divish of the Seattle Times). The 22-year-old would otherwise be eligible for the Rule 5 draft this winter, and Seattle will keep him away from other clubs by adding him to the 40-man.
Seattle acquired Berroa in May, adding him from the Giants in a deal that sent utilityman Donovan Walton to San Francisco. It was the second trade of Berroa’s young career, as he’d previously gone from the Twins to the Giants in a 2019 deadline deal. A native of the Dominican Republic, Berroa draws praise from evaluators for his fastball-slider combination but has some questions about his control.
That was mostly borne out in his 2022 numbers. Berroa split his time between High-A and Double-A, starting all 26 of his appearances. He posted a cumulative 2.86 ERA through 100 2/3 innings, striking out an incredible 36.5% of batters faced. He also walked an elevated 12.6% of opponents, highlighting that his strike-throwing remains a work in progress. Nevertheless, the M’s feel there’s a chance another club would’ve plugged Berroa directly onto the MLB roster next year given the quality of his stuff.
