Seattle Mariners OF prospect Jarred Kelenic should immediately help fantasy baseball managers in each of the five typical roto categories (batting average, home runs, RBI, stolen bases, runs) while also being a points league favorite. A sweet-swinging lefty hitter with power and speed stolen from the New York Mets organization in the potentially lopsided Robinson Cano/Edwin Diaz trade of December 2018, Kelenic, 21, probably could have debuted in the major leagues a season ago, had there been a full season.

Now, after a mere five games at Triple-A Tacoma, the Seattle organization seems to have deemed him "officially" ready. For the record, Kelenic hit .409 in his week at Tacoma, with a pair of home runs, stolen bases and walks, and he hit .293 with a .890 OPS over 178 minor league games and 775 plate appearances, with 31 home runs and 37 stolen bases, and showing plate discipline. While hitting prospects are rarely a guarantee to produce right away at the plate in the majors, Kelenic figures to be different.
