Evidently, the organization is handling Rodriguez much in the same way as it did Jarred Kelenic, who was likewise shut down after playing just three games in the Arizona Fall League. Johns also notes that another Mariners representative, right-handed pitcher Sam Delaplane, will also have his season end owing to triceps tendinitis.
Delaplane and Rodriguez were selected to participate in the league’s Fall Stars Game last weekend after impressive showings competing against other top prospects. Rodriguez, 18, has turned heads as the youngest player in the league. He has steadily climbed prospect lists after a stellar season in which he reached High-A ball—Rodriguez is now touted by MLB Pipeline as the Mariners’ No. 2 prospect—behind only Kelenic—and the 25th-best prospect in all of baseball. In 84 games across two levels of the lower minors, Rodriguez slashed .326/.390/.540 with 12 home runs.
Meanwhile, 24-year-old Delaplane has enjoyed a breakout season and had been enjoying increased exposure for his performance in the Fall League. He reached Double-A, where he threw 37 innings and struck out 58 batters with a minuscule 0.43 ERA. He’s followed that up with a strong AFL showing, having struck out 15 batters in eight innings of work.
